Fertilization by Drone

Foliar fertilization, micronutrients, liquid lime and biostimulants — pinpoint instead of blanket, site-specific based on real crop data.

What is it about?

The principle

Instead of fertilizing the entire field uniformly, our technology works exactly where it is needed. Based on multispectral analysis and an application map, the agricultural drone applies fertilizer site-specifically and at variable rates (variable rate application) — pinpoint accurate, low-drift, soil-friendly and without a single wheel track. Whether liquid fertilizer, foliar fertilization in a tall crop or micronutrients: fertilization from the air opens up time windows in which ground-based machinery has long had to sit out.

The challenge

Why traditional methods hit their limits

Yield loss from wheel tracks

2–10 % of the field area is lost to tramlines.

Over-fertilization

Blanket application without a needs analysis burdens groundwater and your budget.

Soil compaction

Heavy tractors cause lasting damage to soil structure.

How it works

Our approach

Needs assessment

The multispectral drone captures the nutrient requirements of your crop.

Application map

Vegetation indices are turned into a precise prescription map.

Variable rate application

The agricultural drone doses variably — every zone gets exactly what it needs.

Your benefits

What's in it for you

Service area: Lake Constance region, Baden-Württemberg, Bavaria, Southern Germany and Switzerland — further afield on request. Flight planning, airspace clearances and application documentation are handled by our certified drone pilots.

Frequently booked

What we fertilize and apply by drone

Foliar fertilization

Liquid fertilizer for cereals, maize, oilseed rape, beets and potatoes — including late final treatments in a tall crop.

Micronutrients & trace elements

Manganese, boron, zinc, copper, magnesium or sulfur — targeted against nutrient deficiencies.

Liming by drone

Liquid lime on arable land and grassland — on request also in difficult terrain.

Biostimulants & plant strengtheners

Amino acids, seaweed extract, humic acids, effective microorganisms and compost tea — for vigor and less drought and heat stress.

Agricultural drone spreading granules — visible spread cone
Granules & spreader

Spread, not just sprayed

With the spreader unit, our Agras also applies granules: mineral fertilizer, granulated lime or seed — precisely dosed right up to your field boundary. The spread cone in the picture is no montage; this is what a real job looks like.

Net prices, guide values for around 20 km travel, you supply the material. Minimum order 200 €. Several farms on the same day lower the travel cost for everyone. The order portal calculates the exact price for your fields in two minutes.

Cheaper with your neighbours: group dates

When we fly several farms in your area, you share the travel cost. And your confirmed price will not go up, even if someone drops out.

In practice

Worked example: 10 hectares of wheat with manganese deficiency

A farm in the Linzgau sees pale patches in the wheat in May; the multispectral map shows the deficiency clearly in two hollows. We fly a manganese foliar application at 10 litres per hectare while the soil is not trafficable after rain.

Frequently asked questions

What farms ask us beforehand

How does foliar fertilization by drone work?

We fly with 10 to 20 litres of spray mix per hectare in a fine droplet spectrum close above the crop. The fertilizer lands on the leaf, not in the tramline. We agree concentration and rate with you for crop and growth stage.

How much granular fertilizer can the drone handle?

Up to about 100 kg per hectare in one pass; above that we fly twice. Fine-grained fertilizer and seed-fertilizer mixtures we spread evenly right to the field edge.

What about micronutrients and liquid lime?

Manganese, boron, zinc, copper, magnesium and sulphur we apply in a targeted way as foliar fertilization, liquid lime on arable land and grassland. Both also in difficult terrain where the spreader cannot go.

How does the documentation for the fertilizer regulation work?

For each field you receive date, product, rate and area as an application record, suitable for your field records and support schemes. The fertilizer requirement assessment stays with you.

Do I need an application map beforehand?

No. Without a map we fertilize uniformly. With a multispectral map the drone doses site-specifically, so you save fertilizer where the crop is already supplied.

Region

Where we fly

We fertilize from the air in the Lake Constance district, in the Linzgau and Hegau, in Upper Swabia and the Allgäu, plus eastern Switzerland. For foliar fertilization in tall crops and on wet soils in spring the drone is the alternative to waiting. Farms further away we bundle on a single day.
