Pay attention to the method The compound fertilizer is better for the base fertilizer, and the urea is better for the top dressing. Farmyard manure should be combined with deep tillage into the soil tillage layer, or combined with ridges to buckle into the bottom of the ridge. Nitrogen fertilizer with farmyard manure, 30% as base fertilizer, 70% as top dressing, phosphate fertilizer and potash fertilizer as base fertilizer applied once.
Grasping the quantity of chemical fertilizer and farmyard manure application, the dosage is different according to the difference of crop and soil fertility. On the thin ground, the corn is planted, 4 cubic meters of farmhouse fertilizer per 667 square meters, 24 kg of urea, 13 kg of phosphate fertilizer or 13% of 3 13 kg of compound fertilizer; 3 cm of farmer's fertilizer for medium-fertilizer soil, 20 kg of urea or 12 kg of compound fertilizer of 15%; high-fertility soil for farmer's fertilizer 2.5 cubic meters, urea 15 kg
