According to the mechanism of actions of microorganism, they can be classified as: rhizobium fertilizer, nitrogen-fixing bacteria fertilizer(autotroph or commensalism), phosphate-solubilizing fertilizer, silicate fertilizers, bacillus preparations which is on the research and development.

Different fertilizer has its own feature, so their functions are not in full accord with each other. But they have same goals: 1. To promote growth of crops; 2. To reduce the dosage of chemical fertilizer; 3. To reduce cost; 4. To refine the quality of soil and crops; 5. To protect environment.
