Characteristics of bio organic fertilizers:

1、Rich in beneficial microbial communities, strong environmental adaptability, and easy to leverage population advantages. Bio organic fertilizers contain fermentation bacteria and functional bacteria, which have the advantages of strong nutritional function, good rhizosphere growth promotion effect, and high fertilizer efficiency.

2、Bio organic fertilizers are rich in physiologically active substances. To produce bio organic fertilizers, the organic matter needs to be fermented and subjected to harmless and efficient treatment, producing indole-3-acetic acid, gibberellin, various vitamins, as well as physiologically active substances such as amino acids, nucleic acids, auxin, and allantoin.

3、Bioorganic fertilizers are rich in organic and inorganic nutrients, with poultry and livestock manure as the main raw materials. They are rich in organic and inorganic nutrients, including N, P, K nutrients, various medium elements (Ca, Mg, S, etc.) and trace elements (Fe, Mn, Cu, Zn, B, Mo, c1, etc.) as well as other beneficial elements for crop growth (Si, Se, Na, etc.). Therefore, they have the advantages of rich nutrient content, small volume, and suitability for application.

4、After fermentation treatment, bio organic fertilizer is free of pathogenic bacteria, parasites, and weed seeds. The added microbial bacteria are safe and harmless to organisms and the environment, and are suitable for industrial production and meet the needs of large-scale agricultural production. Therefore, bio organic fertilizers have the dual advantages of microbial fertilizers and organic fertilizers, and have significant effects on improving soil fertility, increasing yield, and improving product quality

Mechanism of biological organic fertilizer efficiency

1、The fertilizer efficiency of beneficial microorganisms is significant. Research on the use of microbial organic fertilizer and non microbial organic fertilizer substrates showed that the average yields of spinach and bok choy treated with microbial organic fertilizer were 22.403 t/hm2 and 29.169 t/hm2, respectively, while the average yields of spinach and bok choy treated with non microbial organic fertilizer substrates were 19.095 t/hm2 and 23.982 t/hm2, respectively, with a significant difference of 5%. The comparison of the fertilizer efficiency of chicken manure treated with different microbial bacteria showed that the fertilizer efficiency of chicken manure treated with high-efficiency beneficial microbial bacteria was significantly higher than that of natural bacteria treatment. The underground growth of bok choy treated with beneficial microbial bacteria was better, and the aboveground yield was higher, because the beneficial microbial bacteria in the bio organic fertilizer had solid properties. N, P, K and other nutritional functions, as well as rhizosphere growth promoting functions.

2、The fertilizer efficiency of high-efficiency organic fertilizer is significant. Table 1 shows that compared with traditional organic fertilizer, the fresh weight of commercial vegetables treated with high-efficiency organic fertilizer increased by 21.54%, the fresh weight of roots increased by 13.00%, and the yield increased by 17.44%, all reaching a significant level of 5%. The main reason is that high-efficiency organic fertilizer produces physiologically active substances during fermentation and is rich in organic and inorganic nutrients.

3、 The interaction between microorganisms and organic fertilizers is obvious. Bio organic fertilizers have both individual and interactive effects of microorganisms and organic fertilizers. Domestic and foreign studies have shown that bio organic fertilizers can improve soil physical and chemical properties, promote the effectiveness of fertilizer components, enhance fertilizer utilization efficiency, improve soil microbial quantity, flora, and density, increase beneficial microbial quantity and composition, reduce and inhibit harmful pathogens, improve soil microbial buffering capacity, and promote healthy crop growth.
