Organic fertilizer, also known as farmyard manure, is a slow-release fertilizer that contains abundant biomass, animal and plant remains, excrement, and biological waste.

Organic fertilizer is not only rich in the abundant and trace elements required by plants, but also contains rich organic nutrients, making it a comprehensive fertilizer. In agricultural production, organic fertilizers play a crucial role, which is reflected in the following aspects:

01. Improving soil conditions

The application of organic fertilizer has a significant effect on soil improvement in agricultural production. Its organic matter can optimize the physical and chemical properties of soil, promote soil maturation, enhance soil nutrient retention and supply capacity, and improve its buffering performance. These measures collectively provide an ideal soil environment for crop growth.

2. Increase production and improve quality

Organic fertilizers have become an important source of crop nutrition due to their rich organic matter and diverse nutritional elements. It can not only increase crop yields, but also effectively improve the quality of agricultural products.

Organic fertilizers not only provide necessary energy and nutrients for soil microorganisms during the decomposition process, but also effectively stimulate microbial activity, thereby accelerating the decomposition of organic matter. During this process, various active substances produced have significant effects on promoting crop growth and improving the quality of agricultural products.

02 3. Improve fertilizer utilization efficiency

Although organic fertilizers are rich in nutrients, their concentration is low and their decomposition rate is slow. In contrast, fertilizers have a single nutrient content but high concentration, and their release rate is rapid. By rational allocation and utilization, the overall utilization efficiency of fertilizers can be further improved.

By using organic fertilizers and chemical fertilizers in a reasonable combination, their advantages can be fully utilized and complement each other. The organic acids produced during the decomposition of organic matter can further promote the dissolution of mineral nutrients in soil and fertilizers, thereby improving the utilization efficiency of fertilizers. This synergistic effect is not only beneficial for crop absorption, but also effectively improves the overall utilization efficiency of fertilizers.

03 4. Enhance drought and flood resistance

After applying organic fertilizer to the soil, it can significantly enhance the soils water storage and retention capacity. In this way, crops can be better protected under drought conditions, and their drought resistance will also be enhanced.

After applying organic fertilizer to the soil, it can not only enhance the soils water storage and retention capacity, but also further increase the soils porosity, making the soil structure loose. Such changes can help improve the growth environment of roots, stimulate healthy development of roots, and enhance crop resistance to floods.

04 V. Relieve Environmental Pressure

Organic waste often carries a large number of bacterial eggs, and if not handled properly, these bacteria may spread, leading to an increase in the concentration of ammonia, nitrate, and soluble organic nitrogen in groundwater. At the same time, eutrophication of surface and groundwater will also arise, further causing deterioration of environmental quality and even threatening the survival of organisms.

Therefore, by utilizing these organic wastes as fertilizers in a reasonable manner, the problem of environmental pollution can be effectively alleviated.
