Land, Crop Rotation & Fertilization
Turn your fields into data-driven assets. Plan complex crop rotations, calculate nutrient demand in line with the German Fertilization Ordinance (DüV) — currently with curated reference values for the German state of Hesse (LLH) — and visualize your entire farm layout with geographic precision.
Polygon Maps
Map land boundaries precisely with interactive polygon tools. Store ownership details, soil types, and environmental regulations for each plot.
Planting Plans
Plan multi-year crop rotations using historical data and soil information. Automatically get harvest dates based on crop type and sowing time. Everything at a glance for better harvest planning.
Field Activities
Track irrigation, fertilization, harvests, and other events. View all details for each field, automatically track costs in FarmManager, and plan future activities.
Fertilizer Demand Calculation (DBE) — Hesse
Automatically calculate N, P₂O₅ and K₂O demand per field based on crop, target yield, previous crop, catch crop, soil texture, Nmin value and humus level. Currently based on the LLH Hesse reference values (DBE workbook v5.2), including the Hessian “offtake-only fertilization above 20 mg P₂O₅/100 g” rule. Nitrogen carryover from last year's organic fertilization and three-year compost history is factored in per DüV Annex 3. Additional German states are in preparation.
Fertilizer Catalog
Maintain organic and mineral fertilizers with full nutrient content (total N, NH₄-N, P₂O₅, K₂O, MgO, S). Use system templates for common farmyard manures or capture your own analyses — chargeable nitrogen is calculated automatically using the DüV minimum-credit rate.
Nitrate Vulnerable Zones (§13a)
When fields lie in a nitrate vulnerable (“red”) zone, FarmManager automatically reduces the permissible total N by 20%. You can redistribute the remaining nitrogen across fields — both the original per-field cap and the reduced total are validated live.
N-Plan & Closed Periods
Plan multiple fertilizer applications per field with date, rate and unit. Applied N, P₂O₅ and K₂O are calculated automatically and compared to demand. Statutory N and P closed periods (“Sperrfristen”) appear directly in the team calendar.
Annex 5 (Annual Balance)
One-click generation of the per-field annual fertilization balance per DüV §10 (Annex 5). Demand, applied amounts, balance and the 170 kg/ha organic-nitrogen control value are produced print-ready for the 31 March filing deadline.
