SpotSpraying pays off: Why Lithuanian farms rely on efficiency

Rising input costs and stricter regulations make many farmers rethink their approach to crop care. Audrius Mockaitis explains why Audrokesta opted for a drone from SAM-DIMENSION and what benefits this brings for farmers.

terraHORSCH: What changes do you see in the crop spraying technology market in Lithuania?

Audrius Mockaitis: Over the past 5–7 years, the spraying technology market in Lithuania has changed fundamentally. We see two clear directions: tightening regulations and farmers’ growing need to work more precisely, economically, and sustainably. The EU Green Deal targets, the 50% pesticide reduction strategy, and increasing public pressure regarding environmental protection all directly affect farms. The prices of plant protection products are also rising, so farmers are increasingly calculating not only the cost per hectare but also the real return from each spraying operation.
Farmers in Lithuania are very pragmatic – they quickly noticed that “whole field spraying” no longer reflects reality. Weeds are usually distributed in patches rather than evenly. Naturally, this created demand for technologies that allow spraying only where it is needed.
At Audrokesta, we responded to these changes much earlier, not only when it became a trend. We began exploring PrecisionSpraying at a time when most market participants were merely observing what was happening in Germany or Denmark. We saw that in the future farmers would need solutions that reduce costs, increase accuracy, and allow for more sustainable methods of working. That’s why we invested in this field earlier than most – today this allows us to have real, practical experience rather than just theoretical knowledge.

Why did you choose the offline SpotSpraying system?

The offline SpotSpraying system turned out to be the most logical and practical choice for Lithuanian farms for several key reasons:

  1. The application rate is known in advance. This is crucial for Lithuanian farms which often face limited water supply, complex logistics, or long distances between fields. Knowing the exact rate allows the farmer to plan the spraying volume precisely, avoid overmixing, and save time.
  2. Full compatibility with ISOBUS sprayers. Lithuanian farms use a lot of modern machinery, but no one wants to replace their sprayer or invest in additional modules. The offline system works with all terminals, e.g. the HORSCH eos terminal, but also with many other powerful terminals.
  3. The camera of the drone scans the crops from above with an almost vertical angle. This is especially important in Lithuanian conditions, where crops are often dense and weeds hide between rows. A vertical angle from above allows the drone to “look inside” the canopy and identify weed patches more accurately.
  4. Continuously updated algorithms. As the system is not “locked” inside the sprayer, the customer benefits from a constantly improving weed recognition quality. This matters in Lithuania where the weed spectrum is broad and constantly changing.

For farmers, the most important factors are simplicity, reliability, and clarity.

How do you assess the demand for the SAM DIMENSION drone system in Lithuania?

The market in Lithuania is still in its early stages, but that is precisely where the biggest opportunity lies. Lithuanian farmers are among the most innovative worldwide – they make decisions quickly when they see a clear economic value. Today, interest is growing rapidly, especially among larger farms that already calculate how much they can save by spraying only the weed patches.
For example, a 500 hectare farm with a lot of oilseed rape and wheat can save tens of thousands of euros in a single season. Farmers notice this very quickly.

We invested early because we understood that those who enter the market first gain the most experience and trust. Today, farmers want to work with a partner who has real, proven results – not just someone offering a new product. We feel this in every meeting.

HORSCH and SAM-DIMENSION strengthen their partnership

The partnership, which has been existing since 2019, is now taken to the next level: HORSCH takes a strategic share in SAM-DIMENSION – a logical step for both parties, building on a co-operation that has developed over many years. The partnership will be further intensified in the future. The focus will be on the joint further development of the technology, its even closer integration into HORSCH equipment and the pushing of the practical application.
The objective is to make the potential of SpotSpraying available to agricultural farms as quickly and easily as possible. Both companies will remain independent, and the machines and application maps will continue to be compatible with all manufacturers.

In which crops and which weeds does the system provide recognition?

At the moment, we are mainly working with the following crops:

  1. Winter and spring wheat
  2. Oilseed rape
  3. Barley
  4. Faba beans and peas
  5. Sugar beet

These are the key Lithuanian crops where weed patches cause the greatest losses.

The system very accurately identifies:

  1. Thistles
  2. Dock
  3. Volunteer potatoes
  4. Dicotyledonous weeds in monocotyledonous crops
  5. Monocotyledonous weeds in dicotyledonous crops

In Lithuania, we see the highest demand in oilseed rape and wheat fields, because this is where weed patches are the most pronounced and herbicide costs are highest.

What does the entire service process look like from initial interest to spraying?

The process for the farmer is designed to be as simple as possible and aligned with the workflow of the farms:

  1. The farmer contacts us and specifies the fields that are to be scanned.
  2. The drone scans the field and collects high resolution data.
  3. The data is processed and a SpotSpraying application map is created.
  4. The map is exported to the farmer’s terminal (HORSCH, Claas, John Deere, Trimble, etc.).
  5. The sprayer automatically activates spraying only in the identified patches.

The system integrates without any additional modules — all that is required is an ISOBUS terminal. This allows the system to be used even with older sprayers that still serve Lithuanian farms very well.

What is the drone’s daily performance capacity, and why did you choose a high end system?

Our drone can scan 250–300 hectares per day, depending on terrain, crop density, and weather conditions. This is among the highest performance levels available on the market.

We chose a high end system for several important reasons:

  1. High resolution imaging is essential so that the algorithms can precisely identify weeds even in dense crops.
  2. Large areas have to be scanned in a short time — spring windows in Lithuania are extremely tight, and farmers cannot afford delays.
  3. Reliability — farmers need a professional tool, not an experimental or hobby grade solution.

This technology is built for the use in day-to-day farm operations. This matters immensely: there is no time to experiment with technologies that don’t work 100%.

What are the first experiences this spring?

Several very clear observations have already emerged:

  1. The weed patch maps are extremely precise. Farmers are often surprised to see that the patches are not where they expected them to be.
  2. A significant amount of unnecessary spraying is eliminated. In some fields, herbicide use was reduced by 60–80%.
  3. Farmers quickly see the economic benefit. This is not “technology for the sake of technology” — it provides real savings.
  4. The service strengthens the relationship with the customer. When farmers see real data, they begin to view spraying differently and plan their work more strategically.

Looking ahead, we believe that PrecisionSpraying will become the standard. Drones, artificial intelligence, and targeted application will allow farms to work more economically, sustainably, and efficiently.

Where do you see the future of PrecisionSpraying?

The future is very clear — spraying will be done only where it is needed and only as much as is needed. This means:

  1. Even more precise weed recognition.
  2. Integration with soil, yield, disease, and moisture data.
  3. Automated decision making.
  4. Reduced pesticide use.
  5. Greater yield stability and lower risk.

Lithuanian farmers are modern, quick to adopt innovations, and unafraid of technology. That’s why we believe that within the next 3–5 years, SpotSpraying will become standard practice on many farms — just like GPS control, section control, or variable rate application are today.
