How to apply base fertilizer for better effect

From the perspective of the amount of fertilizer, the specific amount of various fertilizers used as base fertilizer can be determined by referring to the local multi-year field fertilizer efficiency test results and target yield and other comprehensive factors. Generally, about 30% of the total amount of nitrogen fertilizer on high-fertility soil is used as base fertilizer. In fertile soil, 50% to 70% of nitrogen fertilizer is used as base fertilizer, and phosphorus, potassium fertilizer and micro-fertilizer are applied as much as possible at one time.

From the perspective of fertilizer varieties, ammonium bicarbonate in nitrogen fertilizer, general calcium, diammonium, calcium magnesium phosphate fertilizer, and three materials in phosphate fertilizer, potassium chloride, potassium sulfate, plant ash in potassium fertilizer, zinc fertilizer and manganese fertilizer in micro-fertilizer, etc. Suitable as base fertilizer.

In terms of depth, the general base fertilizer should be applied to the entire plow layer, that is, a depth of 15 to 20 cm. For organic fertilizers, nitrogen fertilizers, potassium fertilizers, and micro-fertilizers, they can be mixed and sprinkled evenly on the surface, and then plowed into the soil to ensure that the fertilizers are evenly mixed with the soil of the entire tillage layer.

Due to the poor mobility of phosphate fertilizer, it should be applied in upper and lower layers when applying at the bottom, that is, the lower layer is applied to a depth of 15-20 cm, and the upper layer is applied to a depth of about 5 cm.
