Foliar fertilization, micronutrients, liquid lime and biostimulants — pinpoint instead of blanket, site-specific based on real crop data.
FELDFALKE applies foliar fertilizer, liquid fertilizer, micronutrients, liquid lime and granules by agricultural drone, site-specific from an application map on request and also on soil that cannot be driven on. For farms around Lake Constance, in Baden-Württemberg, Bavaria and Switzerland. Foliar fertilization from 32 € per hectare net including travel (calculated for 40 hectares), the farm supplies the fertilizer; FELDFALKE covers 10 hectares in about two hours.
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.
2–10 % of the field area is lost to tramlines.
Blanket application without a needs analysis burdens groundwater and your budget.
Heavy tractors cause lasting damage to soil structure.
The multispectral drone captures the nutrient requirements of your crop.
Vegetation indices are turned into a precise prescription map.
The agricultural drone doses variably — every zone gets exactly what it needs.
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.
Liquid fertilizer for cereals, maize, oilseed rape, beets and potatoes — including late final treatments in a tall crop.
Manganese, boron, zinc, copper, magnesium or sulfur — targeted against nutrient deficiencies.
Liquid lime on arable land and grassland — on request also in difficult terrain.
Amino acids, seaweed extract, humic acids, effective microorganisms and compost tea — for vigor and less drought and heat stress.
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.
from 32 € per hectareFoliar fertilization and liquid fertilizer from the air, including travel and record, you supply the fertilizer
Net, calculated for 40 hectares of foliar fertilization and about 20 km of travel from Überlingen, you supply the material. Smaller areas cost more per hectare because travel and planning stay the same. Minimum order 200 €. Several farms on the same day lower the travel cost for everyone. You see your price range right below in 30 seconds; after your enquiry we email you a firm quote within 24 hours.
As of 1 October 2026
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.
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.
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.
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.
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.
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.
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.
From 32 € per hectare net including travel; the basis of calculation is in the price box above. 10 hectares cost from around 520 € net. You supply the fertilizer, the minimum order is 200 €.
We take care of the flight planning and the documentation. We check with you beforehand whether your field needs a special permit.
You see the price range right away on this page; after your enquiry we email you a firm quote within 24 hours. We put the flight into the right weather window; we fly 10 hectares in about two hours.
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.
The map that shows where fertilizer is needed and where it is not.
Liquid fertilizer straight onto the leaf, price range up front, firm quote within 24 hours.
Boron, manganese, zinc or lime targeted into the crop.
Granules precisely dosed, even in tall crops.
