What we do?

Soil mapping

As a longtime partner of the US company Veris Technologies, we specialize in providing complete soil mapping services. This includes soil EC, soil organic matter, soil pH on the go, and soil topography analyses. We provide our customers with services for creating complete fertilizing programmes, including soil remediation and restoration programmes. Also, we are doing analyses of achieved yields in relation to the number of fertilizers given.

Soil sampling

We offer our clients comprehensive solutions for soil sampling and compaction measurements. We have our own 4x4 fleet equipped with soil probes for taking samples at a depth of 0-40cm, which has a daily performance of up to 25 representative samples, covering 70 to 150 ha. The vehicle is equipped with precise GPS that guarantees taking samples in the same zone all the time. Samples are taken mainly from a depth of 0-30cm (but we can create a special subzone from 30-60cm).

Soil analysis

Since we are equipped with a complete laboratory, we are performing analyses for our clients with the latest technology of coupled plasma optical emission (ICP-OS) as well as devices for measuring nitrogen (NH4 and NO3) content. Besides chemical analyses, we are also doing basic mechanical ones, in order to determine soil volume and particle size. And last but not the least, we are equipped with devices for soil microbial activity measurements.

VRA management

After performing the above-mentioned mapping, sampling, and analysis operations, we complete the circle, and offer our clients fully digitized and automated technology to plan, measure and create precise maps of fertilizing, planting, irrigation, and crop scouting of the entire field production process. For more details, see the Agtrinity software minipage.

Our approach

We offer our clients comprehensive and tailor-made solutions for precision agriculture programmes, monitoring, and digitization of the entire agri-complex. Depending on the customer’s needs, we are adjusting the service. Our approach always starts with a mapping of soil through which we get high-quality maps of soil type, organic matter, terrain topography, and pH values. What sets us apart from standard service providers is the accuracy and coherence of the results.
Since we're mapping the earth's horizon up to 90 cm deep, we can accurately determine the depth of the earth's horizon. Based on this information, we thoroughly approach soil sampling in a way that performs the same in layers 0-90cm, where we get the most accurate results of phosphorus, potassium, calcium, magnesium, and other microelements in the soil.

Simultaneously with sampling, we also measure the compaction of the terrain up to a depth of 60 cm.
All these input data allow us to create maps of the depth of soil horizon to maximize profits and avoid potential water ponds which ultimately allow the landowner to reach even higher yields. In the laboratory, the tests are conducted with the latest analysis equipment, which precisely determines the contents of all relevant elements in the soil.
After we get the results, customers can access Agtrinity software where they can get deeper insights while monitoring the production process itself. To point out, the Soiltrinity team tracks clients through the entire process of precision agriculture, from soil mapping, through analysis of compaction, sampling, and analysis of elements in the soil, to VRA maps creation and implementation in their own production processes. Through our software Agtrinity, clients can measure the effectiveness of applied technology and compare the obtained yield results.


Why we are soil-centric?

We believe that soil mapped by a suite of sensors is the foundation of precision ag programs because:

1. Soil Matters

Soils are not simply where farmers plant their seed. Soil is fundamental to life on earth. In order to continue to feed the fast-growing population sustainably, there is an urgent need to generate accurate, up-to-date soil health information to support agricultural development, environmental sustainability, and fight climate change.

Water-holding capacity is the single largest driver of yield potential in dryland as well as irrigated crops. Any programme using yield goals should begin with knowing how this characteristic varies across a field.

Nutrient storage and availability affect the number of key elements available for uptake to meet the growing demands of a plant. Because this changes drastically between soil types, any sampling and fertilizing strategy should incorporate soil as a guide.

Infiltration and drainage should be managed to avoid over-saturation but limit excess leaching of nutrients.

Nitrogen cycling changes by soil type, so when these different nitrogen needs and holding capacities are ignored, it leads to yield loss or costly overapplication

Herbicide efficiency and carryover risk requires properly identifying soil type and correct rate of herbicide for successful pre-emergent weed control.

Salinity is a brutal soil condition hindering the growth of crops, but it can be cost-effectively remediated with the site-specific application of soil amendments.

Soil Health and Carbon Sequestration efforts recognize soil is a highly variable, dynamic ecosystem, which can, when managed well, perform many vital functions that improve crop production, the agriculture ecosystem, and ultimately our planet.

2. Soil variability matters

The number one driver of yield is soil. The challenge lies in the fact that soil changes significantly across farm fields and traditional sampling and mapping methods miss or misrepresent those underlying soil properties. New technology enables growers, agronomists, and researchers to measure and map the yield driving soil characteristics at an ultra-high-resolution.

Why Does Mapping Soil Variability Matter?

Uniform rates of inputs and equipment settings fail to match what is optimal for each soil type or condition within the same field.

Uniform rates make moderate errors throughout the field, variable applications based on inaccurate maps often result in much larger errors.

Missed variability leads to missed profitability.
You can’t manage what you don’t measure. And if there are mistakes in the way we measure or map soil, then we create costly mistakes with our fertilizer, seed, and irrigation recommendations.

3. Soil needs equilibrium

A profitable precision farming programme is based on an accurate understanding of the soil. The soil properties with the largest effect on productivity are those determining the amount of water and nutrients that will be available for the crop. A major driver, along with soil organic matter and field topography, is soil texture - the amount of sand, silt, and clay. Soil pH, especially if it’s outside the optimal range for the crop, will play a big role in nutrient availability. To manage crop inputs precisely, these properties must be mapped precisely.
Outdated and coarse-scale soil surveys are likely to cause costly errors, especially when varying seed population, nitrogen, or water. Grid sampling, unless done on a ¼ acre scale, doesn’t come close to the precision needed or what modern planting and fertilizing equipment can achieve. The only affordable and precise option is on-the-go soil sensing.

Technics in the field

Field mapping is done by the mobile laboratory Veris MSP3, which measures 2 to 4 different parameters on the go:

1. Electrical conductivity of soil

What is EC?

Soil EC is soil electrical conductivity – a measurement of how much electrical current soil conducts. It’s an effective way to map soil texture because smaller soil particles, such as clay, conduct more current than larger silt and sand particles. As the EC system is pulled through the field, one pair of coulter-electrodes injects a known voltage into the soil, while the other coulter-electrodes measure the drop in that voltage. EC signal arrays reach (60-90 cm) into the soil. The result: a detailed map of the soil texture variability in the crop rooting zone.

Why it matters?

Soil texture has a major impact on productivity, affecting water holding capacity, cation-exchange-capacity (CEC), drainage, topsoil depth, and nitrogen use efficiency. Whether soil will hold, lose, or use nutrients is strongly related to its texture. Mobile nutrients like nitrogen are leached through light soil and lost through de-nitrification in heavy soil. Immobile nutrients like P and K will vary for many reasons – especially crop removal variances. Soil EC maps define the soil texture variability, so your samples are in the right spot and your prescriptions change where the soil does.


Growers, consultants, and suppliers are using Veris soil EC maps to devise management zones, set sampling locations, vary seed rates, nitrogen, irrigation, and better manage your at-risk nitrate leeching zones – and these are just a few uses of EC maps.

2. Soil organic matter – carbon

What is soil OM-C?

Soil OM-C is a critical soil property that affects both the chemical and physical properties of the soil and its overall health. Properties influenced by organic matter include: soil structure; water holding capacity; diversity and activity of soil organisms, both those that are beneficial and harmful to crop production; and nutrient availability. It also influences the effects of chemical amendments, fertilizers, pesticides, and herbicides. Each % of OM can hold 25,000 gallons of water/ac and mineralize 20-40 lbs./ac of nitrogen. Because it forms slowly over time, it’s an excellent indicator of historical productivity.

Why it matters?

If you want to vary inputs based on productive capacity, a precise map of organic matter is crucial. Soil OM-C is an indicator of past productivity, and a driver of current productivity. Because organic matter forms slowly over time, soils that are higher in organic matter possess improved soil texture, drainage, and other factors that consistently generate additional plant growth – resulting in higher soil OM-C. That increased OM-C level also leads to even higher productive capacity – due to better water and nutrient-holding ability, nitrogen mineralization, and soil structure. On fields where organic matter is added through manure or other amendments, an OM-C map reveals where levels are low and could benefit from additional OM-C.


Most precision agricultural applications can be improved with an accurate OM-C map layer – variable rate population, nitrogen management, sampling zones, soil amendments, herbicides, cultivar selection, and more.

3. Soil PH

About soil pH

Soil pH has a significant impact on nutrient availability, microbial activity, nematode populations, soil herbicide efficiency, and much more.

Why it matters?

Soil pH is an important factor in crop production. Nutrient usage, crop growth, and herbicide activity are all affected by the pH of the soil. Grid samples are simply not dense enough to do the job. Within many hectare grids, there is a wide range of pH values, often ranging from soils that call for lime to soils that are already extremely high in pH.


Put the lime in its place with unmatched precision. On fields with calcareous soils, a Veris pH map will accurately delineate areas that will likely never need liming. Managing high pH areas is equally important for precise applications of gypsum, sulfur, or iron.

4. Field topography

Why does it matter?

The lay of the land affects water infiltration, drainage, nitrogen, and soil loss. Severely sloping soil can exhibit reduced productive potential, often due to topsoil loss. Concave, or bowl-shaped areas, can be poorly drained, especially if they also have clay soils.


Topography is one of the most visible field properties and should be included with soils data in many scouting and variable rate applications, especially those involving irrigation and liquid organic nitrogen applications. Topography used alone can be misleading—not all 2% slopes have the same soil texture or organic matter or yield potential. When coupled with Veris soil sensors, the applications for topography data are even more powerful. The obtained maps are of exceptional quality and precision and allow us to determine the zones of land samples very precisely later on.

Daily performance and quality of maps

Veris MSP3 has a daily performance of 80 to 150 ha, depending on the size of the field, the work requirements, and the width of the transects it makes. We usually use transects of 20 to 30-meter width.
After Veris MSP3 processes obtained raw field data, quality maps are delivered to the lab for further analyses and interpolation, allowing us to accurately determine the variability as well as future sampling zones.
Together with Veris Technologies experts, we fuse maps of EC, pH, OM, and topography into unique maps in the lab. They allow agronomists and farmers to accurately determine the variability of the soil in order to take samples precisely.
For a deeper analysis of soil/plant/management, we use the Agtrinity software, which is specially designed to deliver high quality maps.


Compaction measurement technology

Besides standard sample-taking equipment which is already elaborated, we offer our clients an automated technology for soil compaction measurements for up to 60 cm. In this case, parallel with soil sampling, we get deep insight into soil conditions in terms of compaction and plow pans, which may be crucial for tillage management. The client that decides to measure soil compaction gets digital maps of soil compaction.
With the precise diagnosis of where and at what depth the soil compaction is presented, actions to correct the soil profile can be carried out with precision and economy of resources, as it allows intervention according to the need, generating cost savings. In addition to the accuracy of where to make the correction, the result may indicate less drastic and more sustainable interventions, such as crop rotation and the use of cover crops that have strong root development.

Do we understand what compaction means?

Soil is the basis of any crop and the greatest asset of the producer. Soil life demands specific and continuous care to remain healthy and thus allow maximum productive capacity.

One of the problems that affect the development of the crop and that is hidden from the eyes of those who evaluate visually, is the soil compaction. Several factors contribute to the densification of the soil, such as the traffic of heavy machinery and implements, especially in activities with very humid soil. In areas with the presence of animals, continuous trampling also represents considerable pressure and can cause soil compaction.
In addition to soil fertility, the physical condition must be monitored to allow good root development and water storage. Forming a good soil profile to sustain high productivity can be a long work, but very important for those who want to produce more and with stability.

What are the signs of compaction?

Through Agtrinity software, it is possible to analyze and interpolate samples in multiple layers
getting even better information about soil nutrient status.


Nutrient and biology analysis

Trinity of chemical, biological, and physical analysis ensure the right valuation of soil potential and thus, directly influence landowner profit and sustainability.
When analysing samples, we put special attention to sampling methods to examine the soil results. For example, we determine Phosphorus methods primarily based on pH soil values, thereby ensuring greater safety and reliability of results. All the time, our clients can have real-time insight, through specialized software access and cameras that monitor all analysing operations.
