Innovative drone technology meets biodynamic agriculture: horn manure, horn silica and compost preparations — evenly distributed, right on schedule, soil-friendly.
FELDFALKE applies biodynamic preparations by drone: horn manure, horn silica and compost preparations, in the time window of the preparation calendar and with a record per field for the Demeter documents. For Demeter and Bioland farms around Lake Constance, in Baden-Württemberg, Bavaria and Switzerland. From 32 € per hectare net including travel (calculated for 40 hectares), the farm supplies the stirred preparation; FELDFALKE covers 10 hectares in one morning.
Biodynamic agriculture takes a holistic approach: preparations such as horn manure and horn silica promote soil fertility, plant vitality and ecological balance. Careful, even application is essential — and this is exactly where the drone plays to its strengths.
Traditional application ties up a lot of time and staff — often within narrow time windows.
Heavy machinery puts a strain on the soil, and tramlines cost up to 10 % of yield.
Steep slopes and orchard rows are hard to reach on schedule with a tractor.
We work around your preparation calendar — even at short notice.
The agricultural drone distributes the preparations evenly and with GPS precision across the crop.
You receive proof of application for your Demeter records.
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.
The core biodynamic preparations — sprayed over large areas and in the right time window.
Nettle slurry, horsetail and willow bark extract, garlic extract or whey — organic crop protection from the air.
FiBL-listed and organic-approved products, applied biologically by spray drone.
Effective microorganisms and compost tea for soil life and plant vitality.
from 32 € per hectareHorn silica, horn manure and compost preparations, applied in the right time window, including travel and record
Net, calculated for 40 hectares and about 20 km of travel from Überlingen, you supply the stirred preparation. 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 Demeter farm wants to apply horn silica on 10 hectares in several fields in one morning, in the right window and without driving on the land. We stand ready with the drone filled when stirring is done and fly field by field with the rising sun.
You stir as usual, we apply. So that little time passes between stirring and application, we stand ready with the drone filled when the preparation is done.
Yes. Horn manure in the evening with the descending sun in autumn and spring, horn silica early in the morning: we follow your preparation calendar and the weather, at short notice and at weekends too.
We fly with around 9 litres per hectare in a fine droplet spectrum, evenly right to the field edge. Many farms fly horn silica this way and continue to apply horn manure themselves. We discuss beforehand how you want to handle it.
Yes. For each field date, time, preparation, rate and area, plus the flight log. That is enough for your farm documentation and the inspection.
Nettle liquid manure, horsetail, willow bark, whey, compost tea and effective microorganisms we fly with the same technology, as plant strengthening in arable fields, orchards and vineyards.
From 32 € per hectare net including travel; the basis of calculation is in the price box above. 10 hectares cost from around 510 € net. You supply the stirred preparation, the minimum order is 200 €.

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 cover 10 hectares in one morning.
Demeter and Bioland farms around Lake Constance, in the Linzgau, in Upper Swabia and the Allgäu are the core of our preparation work, plus eastern Switzerland. Preparation windows are short and fall at the same time for many farms: if you coordinate with the neighbouring farm, you share the travel cost.
Horn manure and horn silica, over large areas in the right time window.
Liquid manures, extracts, compost tea and strengthening agents from the air.
For biodynamic winegrowers: plant strengthening on every site, crop protection on steep slopes.
