PRECISION AGRICULTURE
Agriculture today operates in a rapidly interconnected world, and farmers across Europe face similar challenges – rising costs, pressure for efficiency, weather and stricter regulations – making accurate data increasingly valuable.
Drones provide an up-to-date and detailed picture of the condition of the stands: where growth is lagging, where there is stress, nutritional problems or uneven conditions. Instead of estimates, you make decisions based on maps and measurements, you can target interventions only where necessary, reduce costs and stabilize (often increase) yields.
PRECISION AGRICULTURE
Precision agriculture in practice, not just in theory
Precision agriculture means adapting interventions to what is actually happening in the field – because each plot is actually a mosaic of different soils, moisture and vegetation conditions. In Slovakia, this is further accentuated by drought and heat, local torrential rains, places oppressed by technology, different vegetation development after winter, erosion or "hotspots" of weeds, diseases and pests.
The goal is simple: more stable yields, lower costs and less strain on the soil – that is, applying fertilizers and protection only where it makes sense, and in an amount that corresponds to a specific part of the field, not the average.
Why data is key and what we can do with it for your decisions
The first and most critical step in variable rates is to have up-to-date information about the condition of the crop – where growth is lagging, where there is stress, where there is likely a lack of nutrition or a water problem. Without this, variable application is just a “feel-good” approach.
At AuditAir, we collect this information quickly and accurately using drones and transform it into usable outputs for practice – maps and documents compatible with most modern agricultural equipment. In the following sections, you will see what measurements we make, what exactly you can read from them, and how to transform them into a specific intervention plan in the field.
HOW TO USE THIS TECHNOLOGY?
Precision farming technologies bring added value throughout the season - from emergence and crop control, through condition monitoring and targeted interventions, to yield estimation before harvest and planning for the next season based on real data.
01 Checking the condition of the vegetation
Regular overview of where the stand is holding up and where it is losing performance. We will capture weak zones, edges, depressed areas, passes, game spots, damage from young shoots or uneven emergence. In practice, we often reveal things that are not visible from the cabin - for example, gradually expanding "dead" spots, problem rows after sowing, or zones where the stand breaks every year.
The output is clear: a map of zones + a brief interpretation of what is probably the cause and where it is worth going to look at the ground first. Instead of walking "blindly" around the entire field, you save time and have a better basis for decisions - whether it is a correction of fertilization, protection or a plan for further intervention. In the next steps, we can also use these zones as a basis for variable doses or targeted applications.
02 Crop emergence and vigour
After sowing, it is important to quickly know whether emergence is uniform and where failures occur. At the spring start, it is visible which parts of the field are starting slowly, where the growth is "standing still" and where, on the contrary, it is developing excellently. This is where the season often breaks - because early intervention can save the potential and late intervention only "extinguishes".
The data will help you distinguish whether it is more a problem with sowing, soil conditions, oppression or local damage, for example. Instead of making blanket decisions, you can set up a targeted check: look only at critical areas, get a quick overview and make a decision without unnecessary guesswork. The outputs can also be used to compare between plots or hybrids and to better set up the next season.
03 Soil and terrain analysis
In Slovakia, the terrain often matters more than it seems: gentle slopes, old land reclamation, waterlogged areas, compacted passes, differences in soil along historical plot boundaries or after land modifications. The result is that the stand behaves differently in different parts of the same plot – and every year the problems repeat in the same places. We map the terrain and the connections that make a difference in the condition of the stand: where water is retained, where it dries out quickly, where there is a risk of erosion, where crusting forms or where performance is reduced in the long term. This information is excellent for planning passes, dividing zones, stabilizing problem areas and long-term work with the plot. Simply: so that you know why there is a weak spot somewhere – and what can realistically be done about it.
04 Yield potential
Not every part of the field has the same potential – and it is pointless to “push” inputs where they will never return. In Slovakia, this is especially common on plots with significant soil differences, in drier locations or where weak zones after compaction and water stress recur.
We will help you divide the plot into zones according to the performance and condition of the stand, so that you can manage it wisely: support the strong points, address the weak ones in a targeted manner (or manage them differently) and do not shoot doses "blindly". Such zoning is a good basis for variable doses of fertilizers, regulators and for a protection plan. The result is a better cost/result ratio and, most importantly, more stable decision-making across seasons.
05 Early detection of diseases
Diseases usually do not start "everywhere at once". Outbreaks occur - often on the edges, in dense areas, in zones with higher humidity or after damage to the vegetation. Catching them early will save intervention and nerves and often reduce the need for widespread application.
Drone data helps to quickly identify suspicious zones and direct field inspections to where it makes sense. It is not about “remote diagnosis”, but about quickly detecting deviations that are worth checking. In practice, it is mainly about knowing: where there is a risk, where monitoring is sufficient and where action is needed. We can then prepare maps for targeted intervention or at least for accurate documentation of the situation.
06 Damages and documentation
After hail, waterlogging, frost or damage from wildlife, it is important to have quick and demonstrable documentation. Time is often the deciding factor – damage changes from day to day and without clear documentation it is then more difficult to communicate the extent and impact.
We will provide an overview of the damaged areas, their size and a map basis that can be used for internal decisions and communication (e.g. with the insurance company, when registering or when planning further steps). In practice, this means less arguments, fewer estimates and a better overview of what still makes sense to save and where it is better to adjust the plan.
07 Water and plant stress
Moisture stress has been the number one topic in Slovakia in recent years. In some places the growth "stands still", in others it continues - often on the same plot. The differences are made by the soil, compaction, terrain, water retention capacity and local microclimate.
We will help you identify where your crop is suffering from drought, where there is a soil problem, and where it is worth focusing your intervention or changing your management. Thanks to zones, you can plan inspections more effectively, compare plots, and most importantly, make decisions that have an impact: adjusting doses, changing technology, intervening at the right time. It is about making your investment in inputs based on reality – not hope.
08 When to go to harvest
Before harvesting, it is important to know where it ripens earlier, where later, and where the risk areas are (lodging, damage, weak zones). With large areas and limited technology, it is good to have an overview so that the logistics make sense.
The data will help you better plan the sequence of plots, timing and work flow to minimize losses in quality and yield. Practically: less improvisation, better decisions on priorities, and a clear overview for both the agronomist and the mechanizer.
09 Outputs for your machines
We prepare the outputs so that they are usable in practice - zone maps, data for variable doses and brief reports for agronomists. The goal is not to "have a map", but to be able to make a decision and intervention from it.
The goal is for you to be able to work with it right away: in the office and in the field, without unnecessary "IT science". If you use precision agriculture to the fullest, we will also prepare the data so that it can be meaningfully connected to your procedures and technology. And if you are just starting out, we will set up the outputs simply - so that you are clear about it from day one.

Aerial applications with drones
Applications with the DJI T50 and T100 drone
Drone application is not “just spraying from above”. It is an aerial activity with a direct impact on people, property, the environment and your bottom line. That is why it is crucial that it is carried out by a professional with the right permissions, experience and set procedures. At AuditAir, we approach applications as a controlled technical process: before the flight, we evaluate the conditions (wind, temperature, drift, the surroundings of the plot), set safe zones and a flight plan, work with precise navigation and documentation of the work. In practice, this means that the application is accurate, repeatable and defensible – even during a possible inspection.
Why certificates and legal procedures matter
EU rules (EASA) today distinguish where and how you can fly, with what risk and under what conditions. A1/A3 and A2 set limits for safe flying in different environments and distances, STS (standard scenarios) address higher risk operations with specific procedures and requirements. In practical applications, there are often situations where without the right authorizations and processes you simply have no “coverage”.
Equally important are the applicator's authorizations and professional procedures to ensure that the activity is carried out correctly in terms of the use of products, application conditions, protection zones and current restrictions. It is not just about legislation - it is about ensuring that the intervention is carried out effectively, without unnecessary losses and without risk to the environment.
What a professional application will really bring you
Security and compliance – correct categories, procedures, documentation, respecting restrictions.
Accuracy of intervention – application where needed and in the dose according to the assignment (also zonal).
Lower risk of drift and damage – check conditions, correct height, speed, route and surroundings.
Demonstrable record of work – clear documentation of where and how it was applied.
If you want drone application to be a benefit and not a risk, it must be done professionally, legally, and under control. In the following sections, we will show how the application process works, what documents we need from you, and what outputs you will receive.

Regular analyses
Objective: Predictive recording of the condition of the plot and the stand. It is particularly recommended for field crops, vineyards and orchards, where symptoms of infections or nutrient deficiencies can be detected before they are visible to the naked eye.
Frequency: every 7–14 days
Targeted analyses
Objective: to address specific
problems or needs, such as detecting lagging zones or specifying damage. We perform them based on data from regular monitoring.
Frequency: on individually selected days
We can basically divide the season into 3 quarters:
Q1 - winter-spring period,
Q2 - spring-summer period and
Q3 - summer-autumn period.
In the fourth, winter season, we recommend our above-mentioned general analyses

SUMMER AUTUMN
During this period, it is possible to implement foliar fertilization and at the same time evaluate its results - i.e. measure the effectiveness of interventions and their benefit for the stand. Mapping of damage by animals is also relevant, especially in root crops and broad-row crops. AuditAir with drone solutions with advance planning (2–3 months) supports the differentiation of spring regeneration/production doses (fejtragy) and mapping of damage by animals - simply, quickly and effectively.
