Biological bacterial fertilizer/microbial fertilizer/bacterial fertilizer

Biological fertilizer (bacterial fertilizer) needs to be distinguished from bio-organic fertilizer.

Microbial fertilizer is also biological fertilizer, but its essence is not fertilizer. It is just some beneficial fungi cultivated in the soil through some factory methods that are beneficial to the soil and crops.

Classification

1. Bacterial fertilizers with nitrogen-fixing effect: including rhizobia, nitrogen-fixing bacteria, nitrogen-fixing cyanobacteria, etc.;

2. Bacterial fertilizers that decompose soil organic matter : Including organophosphorus bacteria and compound bacteria;

3. Bacterial fertilizers that decompose insoluble minerals in soil: including silicate bacteria, inorganic phosphate bacteria, etc.;

4. Promotion Bacterial fertilizers used by crops to utilize soil nutrients: including mycorrhizal bacteria; 5. Bacterial fertilizers used to resist disease and stimulate crop growth: include antibiotics, production-increasing bacteria, etc.

Advantages

Three or more types of composite bacteria promote and complement each other, and the effect of resisting soil-borne diseases is much greater than that of a single strain. The beneficial bacteria cooperate with each other and act synchronously to achieve high yield and high yield of crops.

1. Increase crop yield

2. Improve crop quality

3. Enhance crop stress resistance

4. Improve fertilizer utilization Rate

5. Improve soil environment
