Expert answer
In short: All phosphorus in autumn, nitrogen split — main top-dressing at tillering, extra at stem elongation only if needed.
| Stage | Nitrogen, N (kg/daa a.i.) | Phosphorus, P₂O₅ (kg/daa) | Potassium, K₂O (kg/daa) | Note |
|---|---|---|---|---|
| Pre-sowing (autumn) | 2–4 | 6–8 (full amount) | 0–6 | Nitrogen only with early sowing or poor soil |
| Early spring (tillering) | 5–6 | — | — | Main top dressing |
| Stem elongation (if needed) | 2–4 | — | — | In a wetter year; for protein |
Guide spring top dressing: 20–25 kg/daa ammonium nitrate (34%) or 18–22 kg/daa UAN. Potassium is usually not essential on chernozems; on lighter soils apply 4–6 kg/daa.
