Fertilizer efficiency is fast, and it is beneficial for crops to absorb in time. The nutrients in chemical fertilizers are mainly inorganic, which need not be transformed and decomposed by microorganisms. The nutrients in the soil will be absorbed by the roots of crops quickly after application. For example, chemical nitrogen fertilizer can be released completely in 3 to 15 days after it is applied to the soil, and can meet the needs of crops quickly in the stage of plant growth. Chemical fertilizers can also be applied through irrigation or even foliar spraying, which greatly improves the efficiency of nutrient uptake by crops.
The fertilizer itself is harmless. Chemical fertilizer has high nutrient content and low impurity. For example, urea contains 46% nitrogen. Nitrogen is the nutrient needed by crops. The rest is mainly CO. When applied to soil, it will be released back into the atmosphere again, is harmless. In addition, it contains about 1% water and about 1% biuret, which is strictly controlled to less than 1.5% harmless to crops and can be decomposed in soil and used by crops and microorganisms. Other phosphate fertilizers, potassium fertilizers and medium and trace elements are extracted from minerals, and the basic components are harmless.
Chemical fertilizers improve soil fertility. There will be different degrees of nutrient deficiency in common agricultural farmland. The application of chemical fertilizer can increase crop biomass, improve surface coverage and reduce soil erosion. In addition, the application of chemical fertilizers to improve crop yield provides a broad space for urban construction, transportation, industrial and commercial development.
According to different soil conditions and crop needs, developing suitable high-efficiency fertilizer products and applying chemical fertilizer scientifically and rationally will greatly help agricultural development.
