Organic fertilizer is a carbon-containing organic material that is fermented and decomposed from plants or animals as the main source. This type of fertilizer can not only improve soil fertility and soil structure, but also provide the nutrients required for plant growth accurately, and ultimately achieve a double improvement in crop quality and yield.
Organic fertilizer can increase the organic matter content in the soil, improve the soil’s water retention, fertilizer retention and air permeability, and the ability to regulate soil temperature, and can improve soil activity and biological reproduction and transformation capabilities, thereby improving the soil’s absorption performance, buffering performance and stress resistance.
Organic fertilizer is comprehensive in nutrition and contains a large number of nutrients, trace elements, sugars and fats required by plants. The use of organic fertilizer can improve the quality indicators of fruits such as moisture, sugar, acid, pectin, pigment, aroma, etc. Organic fertilizer replaces part of chemical fertilizers and coordinates and balances the application ratio of the two, which can reduce the use of chemical fertilizers and improve fertilizer utilization.
Scientific application of organic fertilizers requires reasonable selection of fertilizer types, dosages and application methods according to soil, crop and environmental conditions, so as to achieve efficient and environmentally friendly fertilization goals and promote green development of agriculture.
