Undersowing into the standing crop: maize, cereals, clover — sown quickly and soil-friendly. Plus flower strips, wildlife plots and grassland overseeding.
FELDFALKE sows undersown crops by drone into standing crops such as maize and cereals, as well as flower strips, game cover and grass reseeding, without bending the plants. For dairy and arable farms around Lake Constance, in Baden-Württemberg, Bavaria and Switzerland. From 38 € per hectare net including travel (calculated for 40 hectares), the farm supplies the seed; FELDFALKE sows 10 hectares of maize in about two hours.
Undersown crops support the main crop and improve the soil while it grows — clover undersown in cereals, grass undersown in maize, field beans as a companion crop. Traditionally this takes considerable machinery — by drone, it becomes a short, precise flight into the standing crop, even when the crop is already tall or the soil is wet.
Once the main crop has emerged, the tractor can no longer get through.
Soil trafficability often limits the time window to just a few days.
Your own equipment, your own time — for a task that is easy to delegate.
Optionally with our multispectral drone — we identify where undersowing will deliver the most.
GPS- and sensor-guided seeding, evenly right up to the field boundary.
Proof for subsidy programs and your own 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.
Flowering mixtures for greening requirements and biodiversity — by drone even along field edges and on slopes.
For hunting associations and farmers: sow wildlife forage areas without any tillage.
Ryegrass and overseeding mixtures into grassland — without disturbing the sward.
Documented application as proof for your funded measures.
from 38 € per hectareUndersowing into the standing crop, including travel and application record, you supply the seed
Net, calculated for 40 hectares 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 dairy farm in Upper Swabia wants a grass undersowing in the maize for ground cover in autumn and less erosion in spring. The maize is already knee-high; the tractor would snap plants. We fly 12 kg per hectare in one afternoon before rain.
From the 4- to 6-leaf stage up to about knee height. Later on the drone makes the difference: when the crop is too tall for the tractor, we still fly.
Grass and clover at 10 to 15 kg per hectare, mixtures as per the manufacturer plus 20 percent, because the seed lies on the surface. We calibrate to your seed.
Yes, noticeably. In a summer like 2026 we advise against establishing new undersown crops and prefer to seed a cover crop after harvest into a rain window.
Yes, on field margins, on slopes and on small areas too. Flower mixtures and game cover we apply without tillage; for support schemes you receive the application record.
Yes, ryegrass and overseeding mixtures into the existing sward without disturbing it. Best before rain and after a low cut or grazing.
From 38 € per hectare net including travel; the basis of calculation is in the price box above. 10 hectares cost from around 570 € net. You supply the seed, 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 sow 10 hectares of maize in about two hours.
Dairy and arable farms in Upper Swabia, the Allgäu, the Linzgau and the Lake Constance district call us for undersowing, plus hunting cooperatives for wildlife plots and municipalities for flowering areas. We fly eastern Switzerland regularly too. Small areas we bundle with neighbouring farms.
When seeding after harvest is the better choice than undersowing.
Grass, clover or mixtures into maize and cereals.
Flower mixtures and game cover, on small areas too.
