How to combine fertilizer and farm manure?

How to apply chemical fertilizer and farm manure together? Please introduce that farmers have two incorrect tendencies when applying chemical fertilizer and farm manure: one is to increase production by applying a large amount of chemical fertilizer, which results in an increase in grain production but a great decrease in soil organic matter content, resulting in soil consolidation and a great impact on the production of the next crop. Second, the simple application of farm manure or little application of chemical fertilizer, the result is that although the soil fertility is improved and the production cost is reduced, the grain yield is not high. Practice has proved that if the grain output is to increase year by year and the soil becomes more and more fertile, we must take the road of rational application of chemical fertilizer and farm manure. 1. Use time. The effect of farm fertilizer is slow and should be applied early, generally one-time bottom application before sowing, while less chemical fertilizer should be applied about 7 days before the peak period of crop nutrition absorption. two。 The method of application. Farm manure should be combined with deep ploughing into the soil plough layer, or combined with the ridge into the bottom of the ridge, nitrogen fertilizer matched with farm manure, 30% as base fertilizer, 70% as topdressing, phosphate fertilizer and potash fertilizer applied at one time. 3. Quantity applied. The amount of chemical fertilizer used in combination with farm fertilizer can vary according to crop and soil fertility. for example, planting corn on barren land can apply 4 cubic meters of farm fertilizer, 24 kg of urea, 13 kg of phosphate fertilizer per mu, or 13 kg of 3 15% compound fertilizer. Medium fertility soil can apply 3 cubic meters of farm manure, 20 kilograms of urea, or 12 kilograms of 3 15% compound fertilizer. High fertility soil applies 2.5 cubic meters of organic fertilizer and 15 kilograms of urea. The effect of urea is better when topdressing, and the base fertilizer is the best compound fertilizer.
