1, microbial inoculum: refers to the target microorganism (effective bacterium) after industrial production and propagation, and uses porous substances to absorb the fermentation broth of this bacterium to make a live bacterial preparation.

2. Organic fertilizer: refers to carbonaceous substances mainly derived from plants and/or animals and applied to soil to provide nutrition for plants.

Second, the characteristics are different.

1. Microbial inoculum: it is the carrier of microorganisms and contains no nutrients. After use, it can promote the release of organic fertilizer, chemical fertilizer and mineral nutrients in the soil through the physiological metabolism of microorganisms.

2. Organic fertilizer: contains a lot of beneficial substances, such as nitrogen, phosphorus, potassium, organic acids, peptides and so on.

Third, the usage is different.

1, microbial agent: mostly used as base fertilizer, seed fertilizer and topdressing.

2. Organic fertilizer: Fertilizer has a long validity period and is mostly used as base fertilizer.

Difference between microbial inoculum and organic fertilizer

Fourth, the roles are different.

1, microbial agent: it can improve crop resistance, improve crop quality, inhibit the growth of harmful bacteria in soil and adjust the physical and chemical properties of soil.

2. Organic fertilizer: it can increase the content of organic matter in soil, promote microbial reproduction, improve the physical and chemical properties and biological activity of soil, and provide comprehensive nutrition for crops.
