Fertilizer Buying Guide for Winter Wheat 2026: NPK Program by Yield Target

Start with your yield target#

The single most important decision before buying fertilizer is setting a realistic yield target. That target determines total N rate, NPK ratio, and per-hectare budget. Realistic Ukrainian targets by agro-zone: 4-5 t/ha — baseline for Polissia and northern Forest-Steppe without intensification; 5-6 t/ha — standard for Forest-Steppe with reliable top-dressings; 6-7 t/ha — intensive technology on southern Forest-Steppe chernozems; 7-8 t/ha — maximum for top Poltava and Cherkasy farms with full phase control. Total N for each level: 80, 120, 160, and 200 kg/ha respectively, with corresponding P₂O₅ and K₂O balanced through NPK compounds. If budget is tight, set the target at 4-5 t/ha honestly — an underfunded 7 t/ha program will deliver 5 t/ha at the cost of 6.

NPK program for 6 t/ha#

A typical balanced NPK program for 6 t/ha on Forest-Steppe chernozem: autumn base — NPK 10-26-26, 250-300 kg/ha (25 kg N, 65 kg P₂O₅, 65 kg K₂O) applied under primary tillage 30–40 days before sowing. Autumn starter N — 30-40 kg/ha ammonium nitrate co-applied at sowing to speed root establishment. Spring top-dressing at tillering (BBCH 21–25) — UAN-32 or ammonium nitrate, 80-100 kg N/ha. Second top-dressing at stem elongation (BBCH 30-32) — 40-50 kg N/ha. Third foliar application at heading (BBCH 55–59) — urea 46%, 15-20 kg N/ha together with microelements (Mn, Zn, Cu). Total N — 165-200 kg/ha; P₂O₅ — 65 kg/ha; K₂O — 65 kg/ha. The rate structure closely follows NUBiP Forest-Steppe trials for bread wheat at 28–32% gluten grain quality.

UAN, ammonium nitrate, or urea?#

The choice of nitrogen form depends on three factors: available equipment, farm size, and application phase. UAN-32 is optimal for farms with ≥18 m sprayer booms and 300+ ha; the liquid form allows tank mixing with herbicides and growth regulators, saving 1-2 passes per season. Ammonium nitrate is the classic choice for small and mid farms (under 300 ha) using Amazone, Bogballe, or Kuhn spreaders; best for early-spring top-dressing on thawing soil thanks to instant nitrate availability. Urea is the cheapest per kg N in April 2026 (~48 UAH/kg vs 55-56 for AN and UAN), but has 8-20% volatilization losses without immediate incorporation or NBPT inhibitor. Use only as a base or on moist soil with rainfall forecast in the first 48 hours, or paired with Agrotain/Limus at 180–240 UAH/t.

Per-hectare budget in April 2026#

A realistic per-hectare fertilizer budget for 6 t/ha winter wheat in April 2026: NPK 10-26-26 250 kg × 17,400 UAH/t = 4,350 UAH; UAN-32 350 kg × 17,800 UAH/t = 6,230 UAH (for 100 kg N); ammonium nitrate N33 150 kg × 19,400 UAH/t = 2,910 UAH (for 50 kg N); foliar urea 30 kg × 22,100 UAH/t = 663 UAH. Total fertilizer cost — about 14,150 UAH/ha. For 5 t/ha the budget drops to 11,500 UAH/ha; for 7-8 t/ha it rises to 17,000-18,500 UAH/ha with additional N and micronutrients (YaraVita, Mantrac Pro, or Humifield). Add 2-3% for logistics and 5-7% supplier margin, plus a 4–6% seasonal premium if you buy in April-May rather than locking in by the end of February.

Where to buy in 2026#

Several stable supply sources serve the 2026 Ukrainian market. Domestic production — OSTCHEM and Group DF (Cherkasy Azot, Rivneazot) provide 55-60% of ammonium nitrate and UAN volume. Imports — Yara International (Norway/Poland), EuroChem (international), BASF, and ICL cover the rest plus specialty NPK formulas. Import prices run 5-10% above domestic but deliver stable granulation and transparent logistics. Distributors in Ukraine: Ramzai, Eridon, ATB-Agro, Agroscope, MHP Agro. For April 2026 purchases verify your ammonium nitrate storage permit (precursor material) — State Food Service certificate and inventory logs are mandatory.
