Do you know the difference between organic fertilizer, bio-organic fertilizer and microbial inoculants? In order to better understand and distinguish these three types of fertilizers, we will answer today from three aspects: price, standard and characteristics!

▌Let’s talk about the price first

The price of organic fertilizer is relatively low, the price of bio-organic fertilizer increases, and the price of microbial agents is the highest).

▌Secondly, the definitions of the three products in their corresponding standards

Organic Fertilizer (NY-525-2012)-Industry Standard

Refers to carbon-containing organic materials that are mainly derived from plants and/or animals and are fermented and decomposed. Their function is to improve soil fertility, provide plant nutrition, and improve crop quality. It is suitable for organic fertilizers made from livestock and poultry manure, animal and plant residues, and animal and plant products as raw materials, which are fermented and decomposed.

Agricultural microbial inoculants (GB 20287-2006)-National Standard

Refers to the live bacteria preparations processed by the target microorganisms (effective bacteria) after industrial production and expansion. It has the functions of directly or indirectly improving soil, restoring soil fertility, maintaining the balance of rhizosphere microbial flora, and degrading toxic and harmful substances; it is used in agricultural production, through the life activities of microorganisms contained in it, increasing the supply of plant nutrients or promoting Plant growth, improve the quality of agricultural products and agricultural ecological environment.

Bio-organic fertilizer (NY-884-2012)-industry standard

Refers to a type of fertilizer that is composed of specific functional microorganisms and organic fertilizers that are mainly derived from animal and plant residues (such as animal manure, crop straw, etc.) and undergoes harmless treatment and decomposing. It has both microbial fertilizer and organic fertilizer effects. .

According to the comparison of the definitions of the three products and the corresponding technical indicators, the following differences can be clearly seen:

① Organic matter content: Organic fertilizer (≥45%) and bio-organic fertilizer (≥40%) have clear regulations on the organic matter content, while microbial agents are not.

②The effective number of viable bacteria: bio-organic fertilizer (20 million/g) and microbial inoculants have clearly defined the effective number of viable bacteria. The number of microbial inoculants is higher, and organic fertilizer is not specifically required to be added during the production process. Functional microorganisms, so there is no requirement.

③Validity period: Bio-organic fertilizer and microbial inoculants stipulate a clear validity period. The main reason is that the functional microorganisms added to the product have a specific validity period. If the microorganisms are inactivated, they will not have or reduce the functions and effects of the corresponding products.

What they have in common is: generally the most suitable base fertilizer application!

▍The main functions of the three fertilizers are different!

① Organic fertilizer focuses on increasing soil organic matter and improving soil fertility;

② Microbial agents focus on microorganisms, which do not have or have a small amount of nitrogen, phosphorus and potassium, and are mainly used as carriers of microorganisms. They mainly rely on the physiological metabolic activities of microorganisms to promote organic fertilizer, chemical fertilizer, and mineral nutrients in the soil. The release of microbial secondary metabolites contains more amino acids, hormones and other substances, which can effectively improve the quality of crops and increase the resistance of crops. At the same time, it can also inhibit the growth of harmful bacteria in the soil and adjust the physical and chemical properties of the soil.

③Bio-organic fertilizer is a product with both microbial fertilizer and organic fertilizer effects. It contains not only functional microorganisms, but also a certain amount of organic matter and nutrients.
