Nitrogen Rate Calculator — Wheat, Sunflower, Maize
Free ADAM calculator that computes the optimal nitrogen rate (kg/ha) for the main Ukrainian crops based on target yield, agro-zone, and chosen nitrogen fertilizer. Output: the 60/40 two-pass split and conversion to physical mass of UAN-32, ammonium nitrate, or urea.
UAN-32 Application Planner: Mass, Time, Weather
The calculator returns UAN-32 physical mass, working solution volume, refill count, spraying duration, and a temperature safety window. Green up to 18°C, yellow 19–22°C (dilute 1:1), red above 22°C (reschedule to morning/evening).
Fertilizer Cost Per Hectare Calculator
The calculator converts application rate and price per tonne into cost per hectare, per tonne of yield, and for the whole farm. It also shows fertilizer's share of total production cost — typically 28–38% depending on crop in 2026.
Certified Seeds
3 calculators
Sunflower Seed Density Calculator — Ukrainian Regions
The calculator returns the optimal sunflower plant density (k plants/ha) by region, maturity group, row spacing, and field germination. Output: seeding rate, seeds per meter, and seed units to purchase (1 unit = 150,000 seeds).
Winter Wheat Sowing Rate Calculator (kg/ha)
The calculator returns the winter wheat sowing rate in kg/ha based on target productive stems per hectare (million), thousand-seed weight, lab germination, and purity. Region-aware — Steppe, Forest-Steppe, Polissia.
Sunflower Hybrids in the State Register: Zone and Broomrape
Pick a zone and the page shows the sunflower hybrids Ukraine's State Register of varieties recommends for it as of 28.09.2026, with year, maturity group and broomrape resistance quoted from the variety description. The register states no race: a differential-line test identifies your field's race, the originator's declaration the hybrid for it.

Diesel Bulk Procurement Savings Calculator
The calculator shows annual savings from switching from gas-station retail diesel to EXW bulk tanker delivery. It recommends switching when savings reach ≥5% of annual fuel spend and storage payback is ≤24 months.
Diesel Procurement Timing: 2026 UA Price Cycle
Buy diesel at the right month, save UAH 700K–4M/yr on a 1,500 ha farm. Calculator shows your oblast's best-buy window, on-farm storage ROI, forward-contract hedge value, and 20% counterfeit risk at the pump — all calibrated to the Institute of Consumer Expertise late-2025 survey.
