So far, there are only 400 kinds of microbial fertilizers that have been approved and registered by the state. In fact, there are more than 2,000 manufacturers in the market. The microbial fertilizers sold in the market are mixed. In order to protect the vital interests of farmers, when purchasing and applying The following issues should be noted:
Products that do not have a registration certificate from the Ministry of Agriculture cannot be purchased. The state stipulates that microbial fertilizers must be inspected by the designated units of the Ministry of Agriculture and regular field trials, fully proving that their benefits, non-toxic, and harmless are approved by the Ministry of Agriculture, and are issued to the temporary registration certificate. After three years of practical application, the test is reliable. The official registration certificate is issued and the official registration certificate is valid for 5 years. Microbial fertilizers that do not have a registration certificate from the Ministry of Agriculture may have problems with quality and should not be purchased or used.
Microbial fertilizers with a valid viable count that does not meet the standard cannot be purchased. The state stipulates that the effective viable count of microbial inoculants is ≥200 million/g (particles 100 million/g), and the effective viable count of compound microbial fertilizer and bio-organic fertilizer is ≥20 million/g. If this standard is not met, the quality of the product will not meet the requirements.
Do not use microbial fertilizers that have been stored for longer than the expiration date. At present, the survival time of effective microbial fertilizers in China is less than one year, so the microbial fertilizers to be purchased should be used as soon as possible, and the effect of expired microbial fertilizers is certainly not good.
Storage conditions and methods of use must be strictly in accordance with regulations. Many effective live bacteria in microbial fertilizers are not resistant to high and low temperature and strong light, are not resistant to strong acid and alkali, and cannot be mixed with certain fertilizers and fungicides. When using microbial fertilizers, they must be scientifically preserved and used according to the product specifications.
