First, because of the enthusiasm of fertilization. For example, wheat and potato sorghum, due to early harvest and sufficient leisure time, it is advisable to apply cold fertilizer such as pig manure and cow dung.
Cold. Such as cabbage, rapeseed and other mouthwash, due to late harvest, it is best to use sheep manure, horse manure and other hot fertilizer.
Soft. For example, soybeans and other mouthwashes, the soil is moist and soft, and there are more nitrogen left. It is advisable to apply fertilizers containing phosphorus and potassium.
Hard. For example, corn, sorghum, etc., the soil is tight, and fertilizers with more organic matter should be applied.
Second, due to crop fertilization because legumes have rhizobium, it can fix nitrogen in the air by nitrogen fixation, so less nitrogen is needed, and more phosphorus is needed. Therefore, less nitrogen fertilizer should be considered when fertilizing. In addition to more nitrogen, gramineous crops require more phosphorus and potassium fertilizers. When fertilizing, attention should be paid to the reasonable combination of nitrogen, phosphorus and potassium. Leafy crops require more nitrogen, and fertilization should be based on nitrogen fertilizer.
Third, soil fertilization and fertilization capacity vary greatly due to soil fertilization. The plots with heavy texture and low ground temperature should pay attention to fertilization at the seedling stage. In sandy soils, due to poor fertility, the amount of one application should not be too large and should be applied in divided doses.
Fourth, due to weather and fertilization weather conditions affect the growth of crop roots and the absorption of nutrients, but also affect the state of nutrients in the soil. Therefore, fertilization in the low temperature season should be appropriately advanced as needed. Fertilization in high temperature weather should prevent the effect of fertilizer, and fertilization in rainy days should prevent the loss of fertilizer.
5. Fertilizers due to the nature of fertilizers are generally chemically unstable and volatile fertilizers, such as ammonium sulfate, ammonium nitrate, ammonium bicarbonate, etc. should pay attention to deep application of soil during application, reducing nutrient losses. For the smaller moving phosphate fertilizer, it should be applied as the base fertilizer and seed fertilizer to the root layer. A fertilizer that is easily soluble in water and is suitable as a top dressing. In paddy fields, it is not advisable to apply nitrate nitrogen fertilizer, and ammonium fertilizer should be applied.
