Apply enough potash before OSR drilling

摘要

Growers are being urged to apply sufficient potash before drilling oilseed rape this autumn to boost winter crop survival and maximise yields. Applying potash before planting rape can increase yields and help protect the crop against a harsh winter, says Jerry McHoul, technical UK director of fertiliser firm K -I- S Eire. Maximising the potassium (K) content of a plant's sap helps lower the rape plant's freezing points. "In effect, potassium acts almost like an anti-freeze."
