Classification of microbial fertilizers

Microbial fertilizer is through a specific microbial life activities, increase nutrition or produce plant growth hormones of plants, an article promoting plant growth. Administration microbial fertilizer, is through the artificial inoculation, the microbial fertilizer was added to the large number of beneficial microorganisms and rhizosphere soil of crops, improve soil fertility by their activities, stimulate crop growth and inhibit the activity of harmful microorganisms.

Microbial fertilizers are classified into three types: microbial agents, compound microbial fertilizers and bio-organic fertilizers. It refers to a target microbial agent microorganisms (bacteria effective) propagation After industrial production, as the adsorbent (e.g. peat, vermiculite), adsorbed preparation comprising viable cells of fermentation broth processing using a porous material. The microbial agent is used for seed dressing or rooting , and has the functions of directly or indirectly improving soil, restoring soil fertility, maintaining the balance of rhizosphere microflora and degrading toxic substances.

Compound microbial fertilizer refers to a combination of specific microorganisms and nutrients , which can provide, maintain or improve plant nutrition , improve the yield of agricultural products or improve the quality of agricultural products. According to the different nutrients , it can be divided into microbes and organic compounds, microbes and organic substances and inorganic elements. For example, according to the mechanism of action, it can be divided into nutrition-based, disease-resistant, and degradable pesticides , as well as multiple effects. According to the specific microbial species in the products , the compound microbial fertilizer can also be divided into bacterial fertilizer ( rhizobial fertilizer, nitrogen fixation, phosphorus dissolving, potassium dissolving fertilizer ) , actinomycete fertilizer ( antibiotic fertilizer ) , fungal fertilizer ( mycorrhizal fungi, mold). Fertilizer, yeast fertilizer ) , photosynthetic bacteria fertilizer.

Bio-organic fertilizer refers to a fertilizer that combines specific functional microorganisms with organic materials mainly derived from animal and plant residues ( such as livestock manure, crop straw, etc. ) and is harmlessly treated and decomposed , and has both microbial fertilizers and The double effect of organic fertilizer. Bio-organic fertilizer is divided into two types: Tujia fertilizer ( compost, biogas residue ) and commercial bio-organic fertilizer.
