Microbial fertilizer purchase considerations

The fertilizer market is mixed, and the microbial fertilizers sold in the market are mixed. In order to protect the vital interests of the peasants, they will not be deceived. The farmers should pay attention to the following questions when purchasing and applying:

1. Products that have not obtained the registration certificate of the Ministry of Agriculture cannot be purchased. The state-regulated microbial fertilizer must be inspected by the designated unit of the Ministry of Agriculture and a formal field test. It is fully proved that its benefits, non-toxicity and harmlessness are approved by the Ministry of Agriculture, and it is issued to the temporary registration. The certificate will be issued to the official registration certificate after 3 years of practical application verification. 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.

2, the number of effective live bacteria can not meet the standard microbial fertilizer can not buy the national regulations microbial agents effective viable bacteria number ≥ 200 million / gram (particles 100 million / gram), compound microbial fertilizer and bio-organic fertilizer effective viable count ≥ 2000 Million / gram. If this standard is not met, the quality of the product will not meet the requirements.

3, the storage time exceeds the effective period of microbial fertilizers do not use the current domestic microbial fertilizer effective bacteria survival time is less than 1 year, so the purchase of microbial fertilizer should be used as soon as possible, the effect of expired microbial fertilizer is certainly not good.

4. Storage conditions and methods of use must be strictly in accordance with the 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. Product specifications are scientifically preserved and used.

It is reported that so far, there are only 400 kinds of microbial fertilizers approved by the state for registration, and in fact, more than 2,000 manufacturers have been produced.
