Crops need fertilizer characteristics Cereal crops and leafy vegetables require more nitrogen fertilizers; legume crops require more phosphorus and potassium fertilizers; trace elements silicon and sodium are beneficial nutrients for rice and sugar beets, while most others There is no significant increase in crop yield.
Soil properties Alkaline soil is not suitable for the application of calcium magnesium phosphate fertilizer and phosphate rock powder; the viscous soil can be applied with appropriate amount of slag ash and other materials to improve soil permeability. The sandy soil should be applied with a small amount of quick-acting fertilizer to reduce the loss of fertilizer loss, and apply organic fertilizer. The soil and soil can improve the function of keeping fertilizer and water.
Fertilizer characteristics such as organic fertilizer and slow-acting fertilizer should be used as base fertilizer, and seed fertilizer should choose decomposed organic fertilizer chemical fertilizer that has no effect on seed germination and excavation. Fertilizer which is easy to decompose and volatilize nutrients should be applied deep to reduce nutrient loss and improve fertilizer efficiency.
Meteorological conditions The amount of rainfall and the temperature of the water directly affect the effect of fertilization, such as the weather is dry and unfavorable fertilization, while the rain is too much fertilization, and easy to lose fertilizer. The temperature is high, the rainfall is moderate, and the organic fertilizer is accelerated to decompose. In the low temperature and low rain season, it is suitable to apply the decomposed organic fertilizer and quick-acting fertilizer.
