In agricultural production in many areas, there are two incorrect tendencies in fertilizing farmers' friends: First, the application of chemical fertilizers is large, and chemical fertilizers increase production. Although the results increase grain production, the soil organic matter content is greatly reduced, resulting in soil compaction. It has a greater impact on the production of the next crop; the second is the simple application of farmyard manure or the little application of fertilizer, the result is that although the fertility has been reduced and the production cost has been reduced, the grain yield is not high. In practice, the main reason is that if the grain output is increased year by year and the soil is more and more fertile, it is necessary to take the road of chemical fertilizer and farmyard manure. The main points of its application are as follows:
First, the application time
Farmhouse fertilizers are slow to be effective and should be applied early. Generally, they are applied once before 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.
Second, the application method
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.
Third, the amount of fertilizer
Fertilizer and farmyard manure application, the amount can be different according to crop and soil fertility, such as planting corn on thin soil, 4 cubic meters of farmer's fertilizer per mu, 24 kg of urea, 13 kg of phosphate, or 3 A 15% compound fertilizer is 13 kg; a medium fertility soil can be applied to farmer's fertilizer 3 cubic meters, urea 20 kg, or 3 15% compound fertilizer 12 kg; high-fertility soil Organic Fertilizer 2.5 cubic meters, urea 15 kg. Urea is better used in top dressing, and compound fertilizer is better in base fertilizer.
