Microbial fertilizer refers to a specific product rich in active microorganisms. The application of such fertilizers can supplement and promote the breeding of beneficial microbial populations, improve the soil micro-ecological environment, and inhibit or control the occurrence of soil-borne pests and diseases.
There are many types of microbial fertilizers, which can be divided into bacterial fertilizers, actinomycete fertilizers, fungal fertilizers, and compound microbial fertilizers according to the types of microorganisms in fertilizers. Different types of microbial fertilizers have different effects.
Rhizobium is a common microbial fertilizer that is mainly used in legumes. The inoculation of rhizobia with legumes can fix 150-200 kg/ha of nitrogen during each growing season, which will help improve soil fertility. Biocontrol agents generally adopt the method of seed dressing and root dressing. They can be applied together with the base fertilizer. The bio-control agent and organic fertilizer are evenly mixed, and the application amount is 1-2 kilograms.
