Role of chemical fertilizer

The fertilizer can be absorbed quickly and efficiently. The nutrients in chemical fertilizer are mainly inorganic and do not need microbial transformation and decomposition. After the application of soil nutrients, they will be absorbed by the roots of crops.

For example, chemical nitrogen fertilizer can be completely released within 3 to 15 days after being applied to the soil, which can quickly meet the needs of crops in the growth stage of plants. Chemical fertilizer can also be applied through irrigation or even leaf coating, which greatly improves the nutrient absorption efficiency of crops.

Fertilizer itself is harmless. Chemical fertilizer has high nutrient content and low impurity. Urea, for example, contains 46% nitrogen. Nitrogen is a nutrient for crops. The rest is mainly Co. When applied to the soil, it is released back into the atmosphere again and is harmless. In addition, it contains about 1% of water and about 1% of urine.

It is strictly controlled below 1.5%. It is harmless to crops and can be decomposed in soil and used by crops and microorganisms. Other phosphate fertilizers, potash fertilizers and trace elements are extracted from minerals, and the basic components are harmless.

Chemical fertilizer improves soil fertility. The nutrient deficiency of common farmland is different. Application of chemical fertilizer can increase crop biomass, increase surface coverage and reduce soil erosion. In addition, the application of chemical fertilizer has increased crop yield, providing a broad space for the development of urban construction, transportation, industry and commerce.

According to the different soil conditions and crop needs, the development of suitable high-efficiency fertilizer products and the scientific and rational application of chemical fertilizer have great potential for agricultural development.
