The following three techniques should be noted in the application of chemical fertilizers and farmyard manure:
Attention time The farmer's fertilizer is slow, and should be applied early. Generally, it is applied once before the sowing. However, the amount of chemical fertilizer is small, and the effect is quick. Generally, it should be applied about 7 days before the peak of nutrient absorption.
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, or combined with ridges to buckle into the bottom of the ridge. Nitrogen fertilizer with farmer's fertilizer, 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 amount can be different according to the difference of crop and soil fertility. For example, if corn is planted in a thin field, 4 cubic meters of farmyard manure, 24 kg of urea and 13 kg of phosphate fertilizer can be applied per mu. Or apply compound fertilizer 13 kg; medium fertility soil can apply 3 cubic meters of farmyard manure, 20 kg of urea, or 12 kg of compound fertilizer; high-fertility soil can apply 2.5 cubic meters of farmyard manure and 15 kg of urea.
