Kontur

At the Đurđev farm, practical experience and comparisons between treated and untreated plots demonstrate the importance of supporting crops throughout the growing season.

In agriculture, everything ultimately comes down to measurable results. How much did the crop yield? How much grain was harvested? And did the measures applied deliver results that justified the investment?

Milan Đorđev, an agricultural producer and distributor of Aeouls products under the Kontur brand, has been using Kontur products in his farming operations for years. His experience covers several arable crops, and the results achieved on plots treated with Kontur products, compared with untreated plots, provide a valuable basis for discussing the role of timely and well-planned biostimulant application.

At the Đurđev farm, the approach is not based on a single application during the season. Attention is given to different stages of crop development, from seed treatment to applications during the growing season, with the programme adapted to the needs of each crop.

Wheat: From Seed Treatment to Support During the Growing Season

In wheat production, the programme began with seed treatment using Start, with the aim of supporting the plant from the earliest stages of development.

During the growing season, Contur products were incorporated into the crop protection programme. In the first treatment, Start and Rast were applied alongside fungicides, while Anti-Stress was used during the second spray.

This approach is based on the principle that support for the plant should not end at sowing but should continue throughout its development, when the crop faces changing environmental conditions.

Results at the Đurđev farm: 300 kg/ha more wheat on plots where Kontur products were applied compared with plots where they were not used.

A difference of 300 kilograms per hectare is a measurable result that farmers can assess in terms of their overall production. Across larger areas, this difference becomes even more significant, making it important to monitor results and keep records of the measures applied.

Oilseed Rape: Consistent Application and 350 kg/ha More Yield

Oilseed rape is a crop that requires careful planning of agronomic practices and attention to the plant’s needs throughout its different growth stages.

On Milan Đurđev’s plots, Kontur products were used on several occasions during the growing cycle. The programme included Start, Anti-Stress and Rast, with the aim of supporting the crop at different stages of development.

Result: 350 kg/ha more oilseed rape compared with plots where Kontur products were not applied.

For the farmer, this is an important figure because the yield difference can be expressed in kilograms per hectare and then translated into its economic value based on the selling price of the harvested crop.

However, to interpret the result correctly, other production conditions must also be considered, including the variety, soil conditions, weather and agronomic practices used. Experience from an individual farm provides a useful indication of real-world performance, while repeated trials under comparable conditions allow more reliable conclusions to be drawn about the effects of an application programme.

Maize: Supporting the Crop at Different Growth Stages

In maize, Milan incorporated Kontur products into his crop management programme during the growing season, taking the crop’s development into account and coordinating applications with other agronomic practices.

At the three-leaf stage, Anti-Stress was applied at a rate of 0.4 L/ha alongside the herbicide treatment. Rast was applied twice: first at the five-leaf stage and again at the eight-leaf stage, together with Laudis, at a rate of 0.3 L/ha per application.

This programme illustrates the importance of planning applications throughout the growing season rather than relying on a single treatment. The aim is to support the plant at different stages of development while following the application recommendations for each product and checking compatibility with crop protection products.

Results at the Đorđev farm: 200 kg/ha more maize on plots treated with Kontur products compared with untreated plots.

How Late Can Contur Rast Be Applied to Maize?

One practical point Milan highlights concerns the possibility of applying Rast during the later stages of maize development.

Based on his experience, application can also be considered when the maize plants have grown tall, provided that the machinery can enter the field and the crop can be treated safely. This is important for farmers who want to plan applications according to crop development rather than relying exclusively on a predetermined calendar date.

However, field accessibility is not the only criterion. When considering a late application, farmers should take into account the product’s approved use, the permitted growth stage, the technical capabilities of the sprayer, the risk of crop damage and operator safety. In particular, it is important to verify whether application at tassel formation or after tassels have emerged is permitted by the product’s official instructions.

What Do the Results from the Đurđev Farm Tell Us?

Milan Đurđev’s experience shows why farmers should monitor not only which products they apply but also the results achieved in their fields. Comparing treated and untreated plots can be a useful way to assess whether an investment is worthwhile, provided the plots are comparable in terms of soil, variety or hybrid, sowing date and other agronomic practices.

The following yield differences were recorded at the Đurđev farm:

• Wheat: 300 kg/ha more.
• Oilseed rape: 350 kg/ha more.
• Maize: 200 kg/ha more.

These figures reflect experience from a specific farming operation and should not be interpreted as a guarantee that the same results will be achieved on every field. Yield is influenced by numerous factors, including weather conditions, water availability, plant nutrition, variety selection and the overall agronomic programme.

For farmers, the most important thing is to consider product application as part of a well-planned production system, follow the recommended rates and application timings, and keep records of the results.

Because, at the end of the season, the best measure of the value of any agronomic practice is what can actually be measured in the field.

One of the most important steps in establishing a crop is preparing the seed for germination and early plant development. Once the seed is placed in the soil, it must initiate a series of physiological processes, develop its root system, and establish contact with water and nutrients. That is why it is important to provide the best possible conditions right from the start.

Kontur Start is designed for seed treatment before sowing, with the aim of stimulating germination, root system development, and nutrient uptake during the early stages of plant growth.

For growers looking to improve seed preparation and give their crops a better start to the growing season, Kontur Start represents an important step in crop production technology.

Why Is Seed Treatment Before Sowing Important?

The early stages of plant development play a significant role in the subsequent growth of the crop. After sowing, the seed must initiate germination, develop its root system, and produce a shoot capable of successfully emerging through the soil.

This process can be influenced by temperature, water availability, soil conditions, and the chemical treatments to which the seed has previously been exposed.

Seed treatment with certain plant protection products can present a particular challenge. Depending on the conditions, products containing triazoles may slow early plant development.

For this reason, seed treatment should not be viewed exclusively as a means of protection. It is also an opportunity to support the plant as it initiates germination and develops its root system.

The goal is to provide the plant with favourable conditions for development from the very beginning, helping it use available water and nutrients more efficiently.

How Does Kontur Start Work?

Kontur Start is a complex organo-mineral fertiliser formulated for seed treatment. Its mode of action is based on a combination of humic and fulvic acids, micronutrients, arachidonic acid, and succinic acid.

Each of these components plays a specific role in supporting early plant development.

Humic and Fulvic Acids: Supporting Plant Nutrition

Humic and fulvic acids are important components of Kontur Start.

Humic acids participate in the regulation of plant physiological processes, while fulvic acids contribute to the availability and transport of mineral elements. Their combined action helps plants use available nutrients more efficiently.

During the early stages of development, when the root system is forming and the plant is establishing contact with the soil, efficient water and nutrient uptake is an important prerequisite for further growth.

Arachidonic Acid: Stimulating Early Development

Kontur Start contains arachidonic acid, a component that the technical documentation identifies as playing an important role in stimulating growth.

It supports processes associated with germination and root formation, as well as the activation of certain natural plant defence responses.

The product is applied to the surface of the seed, allowing its components to come into contact with the soil and the developing root system.

Succinic Acid: Supporting Nutrient Uptake

Succinic acid is another component of Kontur Start. According to the technical documentation, it contributes to increased cell membrane permeability and more active nutrient uptake.

This effect is particularly relevant during the early stages of development, when the plant is establishing its root system and laying the foundations for further growth.

The combination of these components is designed to support germination, root formation, and early crop development.

Kontur Start and Seed Germination: Why Is Germination Vigor Important?

Germination is more than the moment when the first root emerges from the seed. It marks the beginning of a process in which the plant activates its reserves, develops its root and shoot, and prepares for independent growth.

In addition to the final germination percentage, germination vigor is also important. It refers to the seed’s ability to begin developing quickly and uniformly.

Kontur Start is formulated to support both processes. Its application may contribute to increased germination vigor and capacity, as well as more uniform seedling emergence.

The technical documentation reports an average increase in germination capacity of 5–8%. However, actual results depend on seed quality, crop species, testing conditions, and conditions after sowing. This figure should not be interpreted as a guaranteed result for every crop or field.

What Do the Trial Results Show?

In one of the trials presented in the technical documentation, seeds treated with tebuconazole were compared with seeds that received both the same chemical treatment and Kontur Start at a rate of 0.2 L/t.

Parameter	Tebuconazole only	Tebuconazole + Kontur Start
Normal germination on day 5	56.6%	77.8%
Total germination on day 5	87.2%	97.5%
Normal germination on day 7	70.0%	91.2%
Total germination on day 7	89.3%	97.5%

The results indicate improved germination dynamics in the tested group in which Kontur Start was added to chemically treated seeds.

These figures represent the results of a specific trial presented in the technical brochure, not a universal prediction of performance under all growing conditions.

Root Development: The Foundation for a More Resilient Start to the Growing Season

A well-developed root system enables plants to use water and nutrients from the soil more efficiently. Root development during the early stages is therefore essential for successful crop establishment.

Kontur Start stimulates root formation and supports improved nutrient uptake through the root system. According to the technical documentation, this effect may be particularly important for plants that need additional support for root development during their early growth stages.

In a wheat biomass trial conducted at the two- to three-leaf stage, the documentation presents the following results:

Parameter	Untreated seed	Kontur Start 0.1 L/t	Kontur Start 0.2 L/t
Root length	4.92 cm	5.44 cm	5.84 cm
Shoot length	13.20 cm	14.08 cm	14.46 cm
Number of roots	4.32	4.72	5.00
Plant weight	0.130 g	0.147 g	0.200 g

These results show differences in the development of the tested plants depending on the seed treatment applied. They should not be interpreted as a guarantee of the same increase in every growing season, but they provide a concrete example of the potential importance of an appropriately selected treatment during the early stages of development.

How Does Kontur Start Help When Treating Chemically Treated Seeds?

Seed protection is an important part of modern agricultural production. However, certain treatments, depending on the active ingredient and growing conditions, may be associated with slower early plant development.

The technical documentation for Kontur Start specifically highlights its use alongside seed treatments containing triazoles.

Adding Kontur Start to an appropriate seed treatment mixture is intended to support germination vigor, root formation, and early plant growth.

For growers, it is important to view seed treatment as a complete process: seed quality, appropriate protection, correct dosage, and the selection of additional products must all be carefully coordinated.

Before combining Kontur Start with plant protection products, the compatibility of the specific formulations should be verified and all application instructions followed.

Kontur Start: Recommended Dosage and Application Method

Kontur Start is applied as a seed treatment before sowing.

The recommended application rate for the complex of humic and fulvic acids with micronutrients and arachidonic acid is 0.1–0.2 L per tonne of seed.

Why Choose Kontur Humat Start?

Choosing the right seed treatment is an investment in the early stages of crop production, when the plant establishes the foundations for further growth and development.

Kontur Humat Start combines several functional components in a single seed treatment programme.

Its key benefits include:

• Supporting seed germination vigor and capacity.
• Stimulating root system formation and development.
• Supporting water and nutrient uptake through the roots.
• Helping plants overcome the slowing of early development associated with certain chemical seed treatments.
• Supporting more uniform seedling emergence and stronger early growth.

Kontur Start is designed for growers who want to plan every stage of production carefully, starting with the seed.

A Good Crop Start Begins Before Sowing

In agriculture, no single product can compensate for every shortcoming in crop production. Seed quality, soil preparation, moisture, temperature, and sound agronomic practices remain the foundations of success.

Nevertheless, a properly selected seed treatment can be an important part of an effective crop management strategy.

Kontur Humat Start supports germination, root development, and early plant nutrition precisely during the period when the foundations for subsequent growth are established.

Prepare your seeds for a successful start to the growing season. Choose Kontur Humat Start and include an appropriate seed treatment in your crop production plan.

The production of wheat, barley, and other winter cereals begins long before harvest. Establishing a good crop stand, developing a strong root system, promoting tillering, and preparing plants for winter are all important steps that influence subsequent yield potential.

However, farmers increasingly have to plan their production under unpredictable weather conditions. A lack of rainfall after sowing, sudden temperature fluctuations, frost, excess soil moisture, and reduced nutrient availability can slow plant development and make it more difficult to achieve the expected yield.

Under these circumstances, alongside appropriate agronomic practices, crop nutrition, and crop protection, biostimulants for winter cereals can also play a role.

Their purpose is not to replace essential agronomic measures, but to support plant physiological processes, help plants use available resources more efficiently, and improve their ability to cope with certain adverse conditions.

Why Is Early Crop Development So Important?

A well-developed crop in autumn provides the foundation for successful growth in spring. Under favorable conditions, plants develop their root systems, produce leaves, and tiller, laying the groundwork for the formation of productive stems.

However, unfavorable conditions can disrupt these processes.

• Insufficient soil moisture can hinder germination and emergence, slow root development, and lead to an uneven crop stand.
• Low temperatures and frost can damage plants, particularly when they are insufficiently developed or have not undergone adequate cold acclimation.
• Excess water and compacted soil can reduce oxygen availability in the root zone and restrict root development.
• Limited nutrient availability can slow growth and development, even when nutrients are present in the soil but are not readily available for plant uptake.

The consequences are not always immediately visible. Poor early development can affect spring tillering, the number of productive stems, and subsequent yield formation.

That is why timely intervention is important, with measures tailored to the actual condition of the crop and soil.

How Can Biostimulants Help Winter Cereals?

Biostimulants are products that support processes related to plant nutrition and physiology. Depending on their composition and mode of action, they can contribute to more efficient nutrient uptake and utilization, improved plant development, and greater tolerance to certain forms of abiotic stress.

Their effects depend on the type of product, application rate, timing, crop condition, and growing environment. It is therefore important to select a product according to the specific objective.

1. Supporting Germination, Emergence, and Root Development

The early stages of growth are critical for establishing a healthy crop. A well-developed root system enables plants to explore a larger volume of soil and access water and nutrients more effectively.

Certain biostimulants, when applied to seeds or to the soil in accordance with product recommendations, can support early growth and root system development.

Uniform emergence and good root establishment provide a more favorable foundation for subsequent plant development. However, biostimulants cannot compensate for a lack of moisture required for germination or correct the consequences of poor soil preparation and inappropriate sowing depth.

2. Improving Nutrient Uptake and Utilization

The amount of nutrients present in the soil is not the only factor that matters. Their availability and the root system’s ability to absorb them are equally important.

Certain types of biostimulants, such as products based on humic and fulvic acids, can support processes associated with nutrient uptake and utilization.

This can be particularly relevant in winter cereal production, where timely and balanced nutrition influences plant growth, tillering, and yield formation.

It is important to emphasize that biostimulants are not a substitute for nitrogen, phosphorus, or potassium fertilizers. When a particular nutrient is deficient in the soil, the deficiency must be identified and addressed through an appropriate fertilization strategy.

3. Improving Tolerance to Abiotic Stress

Drought, extreme temperatures, frost, and other adverse factors can disrupt plant physiological processes and slow growth.

Biostimulants can contribute to improved plant tolerance to specific stress conditions and support recovery after exposure to stress.

In practical terms, biostimulants can be considered part of a broader risk management strategy in crop production, particularly when unfavorable conditions are anticipated or when a crop has already experienced stress.

Nevertheless, no product can guarantee protection against every form of stress. Results depend on the type, intensity, and duration of the stress, as well as the characteristics of the specific product.

When Should Biostimulants Be Applied to Winter Cereals?

The optimal application timing depends on the intended objective, product formulation, and crop growth stage. Since winter cereals have a growing cycle that extends over several months, it is important to identify the periods when biostimulant application can deliver the greatest practical benefit.

Seed Treatment and Application During Early Growth Stages

When the objective is to support germination, emergence, and early root development, products intended for seed treatment or soil application may be considered.

Autumn Growth and Preparation for Winter

During autumn, it is important to provide suitable conditions for root development, leaf formation, and adequate tillering. Biostimulants can play a complementary role within a sound agronomic strategy, but they cannot replace timely sowing, an appropriate plant population, or balanced nutrition.

Spring Resumption of Vegetative Growth

After winter, the condition of the crop should be assessed, including crop density, plant development, and any potential damage. Depending on the identified needs, biostimulant application may be considered to support further growth and more efficient use of available nutrients.

Before or After a Period of Stress

When adverse conditions can be anticipated, biostimulants may be applied before the expected stress event. Following stress exposure, certain products may help support plant recovery.

Not every product is equally effective at every growth stage. Application timing should therefore be determined not solely by the calendar, but also by crop condition, weather conditions, and the intended use of the product.

Biostimulants as Part of a Strategy for More Stable Crop Production

In modern arable farming, making the most efficient use of available resources and reducing the impact of adverse weather on crops are becoming increasingly important.

For winter cereals, biostimulants can be a useful addition to agronomic practices when selected according to plant needs and applied at the appropriate time.

However, the foundations of successful crop production remain unchanged: quality seed, proper soil preparation, optimal sowing dates and seeding rates, balanced nutrition, and timely crop protection.

Biostimulants are most valuable when used strategically as part of a well-designed crop management system, rather than as a replacement for essential agronomic practices.

Because a successful harvest begins with a strong crop foundation and the right decisions throughout the growing season.

In the end, everything on the farm comes down to the same question – what is left in the trailer once the crop has been harvested?

For Radašin Radosavljević, a farmer from the Svilajnac area, the answer was not easy to find this year. The season was exceptionally dry, with very little rainfall, which made it particularly important to see how the crops would perform where Contur AntiStress had been applied.

Radašin used the product on two crops – corn and sunflower. Both hybrids were from the LG group, but the approach was not the same for the two crops.

In corn, AntiStress was applied as a foliar treatment together with the crop protection treatment, at the 5–7 leaf stage, at a rate of 0.5 L/ha.

In sunflower, the approach was somewhat different. AntiStress was applied for as long as it was possible to enter the crop with a sprayer, also at a rate of 0.5 L/ha.

But simply looking at the crop and saying that it looked good was not enough for Radašin.

He wanted to see the numbers.

That is why he also left untreated areas in the fields, allowing him to compare the yields and see whether the difference could actually be measured once the crops were harvested.

When a Field Result Becomes a Number

Corn may be the best example.

On the part of the field where AntiStress was not applied, the yield was 5,890 kg/ha.

On the treated part, the yield was 3.2% higher.

That means approximately 6,078 kg/ha, or around 188 kg more per hectare.

When this difference is calculated using the corn price at the time, 22 RSD/kg, it represents approximately 4,147 RSD/ha in additional crop value, before deducting the cost of the treatment itself.

At first glance, 3.2% may not sound like a large figure. But when the percentage is translated into what a farmer actually sees on the scale, the picture looks different – almost 190 kilograms more corn from one hectare.

And then there is sunflower.

On the untreated part of the field, the yield was 3,740 kg/ha, while the part treated with AntiStress recorded a 2.8% higher yield.

That corresponds to approximately 3,845 kg/ha, or around 105 kg more per hectare.

At a sunflower price of 50 RSD/kg, those additional 105 kilograms represented approximately 5,236 RSD/ha in additional crop value, again before deducting the cost of the treatment.

Taken together, the two results represent approximately 9,383 RSD/ha in additional crop value, based on the difference between the treated and untreated areas.

Crop	Untreated	Treated	Difference	Price	Additional value
Corn	5.890 kg/ha	6.078 kg/ha	+188 kg/ha	22 RSD/kg	+4.147 RSD/ha
Sunflower	3.740 kg/ha	3.845 kg/ha	+105 kg/ha	50 RSD/kg	+5.236 RSD/ha
Total	—	—	—	—	+9.383 RSD/ha*

Of course, no field result should be viewed separately from the season in which it was achieved.

And this year, water was scarce.

Very scarce.

Under such conditions, it was precisely this that made it interesting to observe how the crop would respond where AntiStress had been applied.

Radašin did not start from the assumption that the product would perform a miracle. He did what farmers know best – he left room for comparison and let the field have the final say.

Because once the crop is harvested, the story is no longer simply about how it looked during the growing season.

What remains is the yield.

What remains is the difference between the treated and untreated areas.

And, ultimately, what remains is the question that matters most to every farmer – can what was done in the field also be seen in the final calculation?

In Radašin’s case, this year’s comparison showed a difference in both corn and sunflower.

And that is precisely why results from real farms have their value – not as a promise that every field will deliver the same result, but as the experience of one farmer under very specific production conditions and an exceptionally dry growing season.

At first glance, the story seems simple: barley, wheat, and one product applied several times throughout the season. But when you talk to Florian Farkaš, it quickly becomes clear that what happens in the field cannot be viewed through the lens of a single product.

Florian works in regenerative agriculture and also provides agricultural advisory services. His approach to production is therefore somewhat different. He looks at the crop, the soil, and plant protection as parts of one interconnected system.

It was precisely within this system that the idea emerged to see how Kontur AntiStress would perform on his barley and wheat fields.

“Since this is my production based on a regenerative system, the idea was to see whether we could replace some of the conventional chemistry, primarily in barley,” Florian explains.

So, the question was not simply what the product would do as a biostimulant. It was also important to see how the crop would perform from a plant protection perspective.

Three treatments were carried out on the barley during the season. Each time, the product was applied at a rate of 0.5 L/ha, generally at intervals of around ten to fourteen days.

This timing was not accidental. Several different treatments were being carried out on the fields during that period, including herbicides and foliar urea applications, so the use of AntiStress fitted into the existing production schedule.

“If there wasn’t a herbicide application, then we applied urea or some similar combination,” Florian says, explaining what the season looked like in practice.

And this brings us to what was, in fact, the most important thing to monitor.

What was happening with the diseases?

According to Florian, the previous season was quite favourable for disease development. And that was precisely what made it possible to see how this approach would perform under real field conditions.

“From a plant protection perspective, the product did the job,” he says.

AntiStress was also applied to wheat, and here too, when it came to the first leaf-protection treatment, no fungicide was used.

However, Florian immediately adds an important point when putting any field result into context.

These are not fields managed in the same way as a conventional field where the same plant protection programme is followed every year.

The wheat has already been grown under a regenerative production system for nine seasons. The way the crop is established also plays a role: the row spacing is 23.3 centimetres.

“This makes the conditions somewhat less favourable for the development of these diseases, especially in barley,” Florian explains.

That is why his result should not be read as a simple equation: one product replacing one fungicide.

Quite the opposite.

What makes this experience interesting is precisely the way he looks at the field as a whole: a production system that has been developed over many years, the way the crop is grown, the conditions in which disease develops, the application of other products and, ultimately, what can be observed on the plants throughout the season.

In the field, these things are difficult to separate from one another.

And perhaps that is the most interesting part of this experience.

Because when we ask a farmer what they gained from using a product, the answer is not always just a number. Sometimes, it is what they saw on the plant. Sometimes, it is a treatment they did not have to carry out. And sometimes, the most important question is the one Florian asked at the very beginning: how much can an existing production system be changed while keeping the crop protected and stable?

As always, the answer is found directly in the field.

Drought. High temperatures. Reduced nutrient uptake. Soil compaction. Less and less time for proper field preparation.

These are no longer problems that farmers have to deal with only in extreme years. They are becoming part of the growing conditions that farmers need to take into account.

And when a plant cannot make full use of the water and nutrients available in the soil, the problem is not always simply the amount of inputs we have applied. The question is also what is happening to the soil in which that plant is expected to grow.

This is where biostimulants come in.

A Biostimulant Is Not a Fertilizer – and Should Not Be Treated as One

The first thing that needs to be clarified is that a biostimulant is not a substitute for basic fertilization, nor can it compensate for poor agricultural practices overnight.

Its role is different.

Biostimulants work by supporting natural processes in the plant or its surrounding environment. Depending on their type and composition, they can contribute to more efficient nutrient use, root development, tolerance to abiotic stress, and certain physical, chemical, and biological processes in the soil.

That is why it is important not to ask only:

“What have I added to the soil?”

but also:

“How much of what is already in the soil can the plant actually use?”

What Happens When the Soil Does Not Have Enough Water?

In recent years, Serbia has experienced periods when high temperatures and insufficient rainfall occurred precisely when crops needed water the most.

Under such conditions, plants close their stomata, physiological processes slow down, growth is reduced, and nutrient uptake and transport can become more difficult.

But drought is not only a plant problem.

Drought is also a soil problem.

Soil with good structure and a greater capacity to retain water responds differently to periods without rainfall than soil that is degraded, compacted, or low in organic matter.

That is why dealing with the consequences of drought does not begin only when the crop is already showing signs of stress.

It begins much earlier – with proper soil management.

Where Do Humic Acids Fit In?

Humic acids are one example of a biostimulant component that can be particularly relevant when we talk about soil.

Their value does not simply lie in “feeding” the plant.

Humic substances contain numerous functional groups that can bind ions and participate in nutrient exchange processes in the soil. As a result, they can contribute to the soil’s capacity to retain and exchange certain nutrients and to their availability to plants.

But their role does not end there.

Humic substances can also influence soil aggregation and structure, affecting the way soil particles bind together to form more stable aggregates.

Soil structure, in turn, affects the movement of water and air through the soil, root development, and the soil’s ability to retain water.

Humic substances can therefore help the soil function more effectively as the environment in which the plant grows.

What About the Nutrients Already Present in the Soil?

This is one of the issues that is often overlooked.

A farmer may have nutrients present in the soil, but that does not automatically mean that they are in a form that is readily available to the plant.

Nutrient availability is influenced by pH, organic matter content, moisture, microbial activity, and many other factors.

Therefore, increasing the amount of fertilizer applied does not necessarily mean increasing production efficiency.

Depending on their type and composition, biostimulants can support processes that influence nutrient availability and more efficient nutrient use.

The point is to make better use of the resources that are already there.

The Soil Does Not Finish Its Job When the Harvest Is Over

This becomes particularly important when preparing the soil for autumn sowing.

After harvest, the soil is left with crop residues, altered moisture levels and structure, and often the effects of months of intensive machinery traffic.

If the season has been dry, the soil may already be under additional stress. If there have been numerous machinery passes, compaction can become another problem.

And then the next crop arrives.

That is why soil preparation before autumn sowing should involve more than simply asking whether the field has been sufficiently worked and leveled.

We should also consider:

• whether the soil can absorb and retain water,
• whether roots can penetrate it without restriction,
• whether there is sufficient biological activity,
• how available nutrients are to the crop,
• and what condition the soil is in as it enters the new production season.

This is where biostimulants can become one part of a broader soil management strategy.

What Does This Mean in Practice?

Imagine two fields.

Both have received basic fertilization and both have been planted with the same crop.

But one has better soil structure, a better water regime, and a more active biological environment.

In a year with sufficient rainfall, the difference may not be dramatic.

But when drought, high temperatures, or another stress period occurs, every difference in the soil’s ability to provide the plant with water, air, and nutrients becomes more important.

That is why soil health cannot be assessed solely through a single soil analysis or a single yield result.

It is about the soil’s ability to perform its functions year after year.

The goal of biostimulants is not to do the work instead of the soil and the plant.

Their role is to help them make better use of what they already have.

And in conditions where every millimeter of rainfall, every kilogram of nutrients, and every machinery pass comes at a cost, efficiency becomes one of the most important issues in modern agriculture.

The application of total herbicides is an important step in weed control and soil preparation for the next growing season. However, treatment performance and soil conditions following application depend on several factors. Combining a total herbicide with an appropriate biostimulant, such as Kontur Humat, can contribute to more efficient treatment and the creation of favorable conditions for further crop development.

More Than Weed Control

Total herbicides are used to control unwanted vegetation, including weeds and certain plant residues, in accordance with the registered purpose of the product. Their effectiveness depends on weed species, growth stage, weather conditions, and proper application.

Kontur Humat is a biostimulant based on humic and fulvic acids, designed to support soil processes and improve the availability of nutrients. When applied together with a total herbicide, the goal is not only to eliminate weeds, but also to improve the conditions in which the soil continues to function after treatment.

Enhanced Total Herbicide Performance

One of the important benefits of combining Humat with a total herbicide is its potential to improve the efficiency of the applied treatment.

Humic and fulvic acids can contribute to more favorable soil conditions and better utilization of certain treatment components. In this way, Kontur Humat can be part of a strategy aimed at enhancing the performance of total herbicides.

However, effectiveness depends on the specific herbicide, weed species, application conditions, and product compatibility. Therefore, the combination must be used in accordance with the product label and manufacturer’s recommendations.

More Rational Use of Inputs

Optimizing herbicide application is an important goal of modern agricultural production. Reducing unnecessary costs and using inputs more efficiently have a direct impact on production economics.

Kontur Humat can contribute to a strategy aimed at optimizing treatment practices. However, the possibility of reducing herbicide rates should not be regarded as a universal recommendation. Application rates must not be reduced arbitrarily, but only on the basis of registered instructions and confirmed results for the specific combination.

Supporting Soil After Treatment

Soil is more than a growing medium for plants. It is a complex system in which numerous physical, chemical, and biological processes take place. Its condition affects nutrient availability, root development, and the performance of the following crop.

The application of Humat can contribute to improving certain soil properties and creating more favorable conditions for plants. Its role in supporting nutrient availability is particularly important when preparing soil after harvest.

Optimizing Soil pH

Soil reaction, expressed as pH, is one of the factors that influence plant growth and nutrient availability. When pH is unfavorable, certain elements may become less accessible to plants, even when they are present in the soil.

Kontur Humat can be part of a soil management program aimed at improving conditions for nutrient uptake. However, humate is not a substitute for liming or other corrective measures when soil analysis shows that they are necessary. Proper assessment of soil pH and knowledge of soil type are essential for making an appropriate recommendation.

Accelerating the Decomposition of Crop Residues

After harvest, stubble and crop residues remain in the field and represent an important part of the soil organic matter cycle. Their decomposition depends on several factors, including moisture content, temperature, the carbon-to-nitrogen ratio, and microbial activity.

Including Humat in a post-harvest program can contribute to creating favorable conditions for soil processes. However, the rate of stubble decomposition is not determined by the application of a single product alone. Proper crop residue management, sufficient moisture, and appropriate agronomic practices are essential for achieving reliable results.

Improved Nutrient Availability for the Next Growing Season

Humic and fulvic acids play an important role in interactions between soil, nutrients, and plants. Their presence can contribute to the improved availability of certain nutrients and more efficient use of soil resources.

For farmers, this means that Humat application can be viewed as part of a broader plant nutrition and soil fertility management program, rather than as a replacement for basic fertilization and proper crop nutrition planning.

Proper Application Is the Foundation of Success

The effects of combining Kontur Humat with a total herbicide depend on the proper selection of products, application rates, water quality, weather conditions, and application method. Before mixing, compatibility must be checked and the instructions for use must be followed.

When Kontur Humat is applied together with a total herbicide, the goal is to look beyond immediate weed control and adopt a more long-term approach to soil management. More efficient use of the treatment, support for nutrient availability, and the creation of favorable conditions for the next growing season are important elements of rational agricultural production.
