1. Organic nutrients and active substances such as amino acids, humic acids, sugars, and degradation products of nucleic acids can be directly absorbed by crops and stimulate root growth. Organic fertilizers contain a large number of microorganisms that can accelerate the decomposition and cycling of organic nutrients in the soil.

2. Organic fertilizers can increase soil organic matter and improve soil physical and chemical properties. Increasing the application of organic fertilizer and continuously improving the soil organic matter content are the main steps in improving soil fertility. Organic matter can increase soil aeration, permeability, water storage, and improve root growth environment, enhancing soil water and fertilizer retention capacity.

3. Organic fertilizers provide a large amount of organic nutrients and active substances to the soil, such as amino acids, humic acids, sugars, and degradation products of nucleic acids, which can be directly absorbed by crops and stimulate root growth. Organic fertilizers contain a large number of microorganisms, which can accelerate the decomposition and cycling of organic nutrients in the soil.

The excessive use of chemical fertilizers or improper nutrient distribution ratio in organic fertilizer equipment can lead to a decline in the quality of agricultural products. The combination of organic fertilizer and chemical fertilizer in compound fertilizer equipment can increase the protein and amino acid content of crops, while also reducing the nitrate content in vegetables and increasing the vitamin C content. The increase in the content of amino acids in plants helps to enhance their stress resistance and resistance to pests and diseases.
