At present, there are many kinds of organic fertilizers, including bio-organic fertilizer, trace element organic fertilizer, bio-humic acid organic fertilizer and so on. However, the common point is that the total content of N, P, and K in the nutrients is generally not more than 6%. Friends often confuse the role of organic fertilizer with the role of chemical fertilizer or compound fertilizer. The content of organic fertilizer is organic matter and humus, which is very important for soil restoration. The purpose of using organic fertilizer is to repair the hardening, salinization, poor permeability, and poor fertilizer and water retention capacity of cultivated land. By improving and restoring the health of the soil, the goal of increasing crop yields and fertile farmland can be achieved.

By applying organic fertilizers to improve arable land, soil fertility and water retention capacity can be improved, fertilizer utilization rate can be improved, and the purpose of gradually reducing the amount of fertilizer application can be achieved. However, the content of nitrogen, phosphorus, and potassium in organic fertilizers is limited, and it is difficult to meet the nutritional requirements of normal crop growth. Therefore, the combination of organic fertilizer and chemical fertilizer is the correct way to use it. The main function of organic fertilizer is to improve the soil and provide nutrients at the same time, so apply it early. Generally used as a base fertilizer before sowing or planting, combined with deep ploughing, so that the soil and organic fertilizer are fully mixed

The purpose of good soil. It is decomposed before use, but the effect of top dressing in the later stage is not as obvious as that of base fertilizer.

Biological bacterial fertilizer can only exert its antimicrobial effect after it multiplies in the soil, so it should be applied as soon as possible before planting in order to have time to multiply and grow. It can be applied to the soil together with organic fertilizer, or applied to acupuncture points before or during planting. The same biological fertilizer can be applied repeatedly in the later stage to strengthen the flora, improve the solubilization ability of phosphorus and potassium and the effect of disease prevention. Different crops require different amounts of fertilizer at different growth stages, so do not apply more or less. Fertilization should be carried out according to the different proportions of crops, and pay attention to the content of nutrient elements in the soil.

The organic fertilizer fermentation tank is an environmentally friendly equipment that uses the decomposition of microorganisms in nature. The organic solid waste is continuously aerobic fermented in a closed fermentation tank for about 7 days, and after microbial fermentation, deodorization, and decomposition, it is processed into bio-organic fertilizer that can be used for crops.
