In agricultural production in many areas, there are two incorrect tendencies when farmers are fertilizing: First, a large amount of fertilizer is applied, and fertilizer is used to increase production. Although the result is increased grain production, the soil organic matter content is greatly reduced, resulting in soil compaction. It has a great impact on the production of the next crop; the second is the simple application of farmyard manure or the little application of chemical fertilizer. The result is that although the fertility has been reduced, the production cost is reduced, but the grain yield is not high. Practice has proved that if the grain output is to increase year by year and the soil is more and more fertile, it is necessary to take the road of chemical fertilizer and farmyard manure.
1. Time of administration. 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.
2. Method of application. The farmyard manure should be combined with deep tillage and applied to the soil tillage layer, or combined with ridges and buckled into the bottom of the ridge, and the nitrogen fertilizer with the farmyard manure, 30% as the base fertilizer, 70% as the top dressing, phosphate fertilizer and potash fertilizer applied once.
3. The amount applied. Fertilizer and farmyard manure can be used together. The amount can be different according to crop and soil fertility. For example, planting corn on thin soil can apply 4 cubic meters of farmyard manure, 24 kg of urea, 13 kg of phosphate fertilizer, or 3 15% of compound fertilizer 13 kg. Medium-fertile soil can be applied to farmhouse manure 3 cubic meters, urea 20 kg, or 3 15% compound fertilizer 12 kg. The high-fertility soil applies 2.5 cubic meters of organic fertilizer and 15 kilograms of urea. Urea is better used in top dressing, and compound fertilizer is better in base fertilizer.
