The chemical fertilizer applied in China mainly comprises nitrogenous fertilizer, but phosphate fertilizer, potash fertilizer and compound fertilizer are less, and long-term application can cause soil nutrient imbalance and accelerate soil acidification. The application of the organic fertilizer can improve the soil structure, improve the absorption capacity of the soil and increase the adsorption capacity of soil colloid on toxic substances such as heavy metals and the like. Therefore, at present, China advocates applying organic fertilizers to farmlands.

The organic fertilizer is mainly derived from plants and/or animals, is a carbon-containing material which is applied to soil to provide plant nutrition as a main function, contains comprehensive nutrient substances, not only contains nitrogen, phosphorus and potassium, but also contains calcium, magnesium, sulfur, iron and a plurality of trace elements, can provide comprehensive nutrition for crops, has long fertilizer efficiency, can increase and update soil organic matters, promotes the propagation of microorganisms, improves the physicochemical property and the biological activity of the soil, and is a main nutrient for green food production. However, most of the nutrient elements of the organic fertilizer are organic substances, and are difficult to be directly absorbed and utilized by crops, and nutrients are gradually released through the chemical and physical action in soil and the fermentation and decomposition of microorganisms.
