The first is to grasp the application time. Large amounts of organic fertilizers are effective and should be applied as early as possible. Normally, base fertilizer should be applied before sowing. Fertilizers should be applied at a low rate and they should be applied about 7 days before the crop needs fertilizer.
The second is to master the application method. Organic fertilizers should be applied to soil tillage in combination with deep tillage. Nitrogen fertilizers used with organic fertilizers should be used as base fertilizers or top dressings, and phosphate fertilizers can be used as base fertilizers together with organic fertilizers.
The third is to control the amount of fertilization. Fertilizers are used in conjunction with organic fertilizers, and the amount can be different depending on the crop and soil fertility. Such as rice, in low fertility soil, can apply organic fertilizer 1000-1500 kilograms, urea 10-15 kilograms, compound fertilizer 40-45 kilograms, potassium chloride 10-12 kilograms per acre; in medium fertility soil, can be Organic fertilizer 500-1000 kg, urea 8-10 kg, compound fertilizer 35-40 kg, potassium chloride 8-10 kg; on high fertility soil, organic fertilizer 500 kg per acre, urea 6-8 kg, Compound fertilizer 35-40 kg, potassium chloride 6-8 kg.
