Microbial fertilizer is a good thing. How to buy it without being "fooled"?

Although microbial fertilizer does not have the ability to directly provide nutrients to crops, it has many advantages such as improving fertilizer utilization efficiency, improving crop stress resistance, and improving soil, and is highly sought after by many farmers. It is a good thing, but the microbial fertilizers on the market are mixed, and many unscrupulous merchants are also trying to get side effects. So how do you choose microbial fertilizers without being cheated? Today we will talk about the pitfalls that should be avoided when purchasing microbial fertilizers.

1. Look at the fungi

Currently, microbial fertilizers are mainly divided into three types according to fungi. The first is improved soil with jelly-like Bacillus as the main component. Biofertilizers for fertile soil and fertile fields; the second is biofertilizers that produce hormones to promote growth; and the third are biofertilizers for prevention and control with Bacillus licheniformis and Bacillus subtilis as the main ingredients. It is generally recommended to choose fertile soil and disease-resistant microbial fertilizers, because the application of hormone-producing biofertilizers on crops can easily cause the crops to lose fertilizer in the early stages of growth and later in the period. So don’t make the wrong choice when choosing.

2. Look at the production license and implementation standards

Microbial fertilizers produced by regular manufacturers must have a fertilizer registration license issued by the Ministry of Agriculture and product quality standards on the packaging bag standard.

Currently, microbial fertilizers are classified according to different standards. Microbial fertilizers are divided into microbial inoculants, microbial fertilizers, and bio-organic fertilizers, which implement different quality standards respectively. Microbial inoculants: The standard for microbial inoculants is "Agricultural Microbial Inoculants GB20287-2006". Microbial fertilizer: The standard implemented for compound microbial fertilizer is "Compound Microbial Fertilizer NY/T798? 2004". Bio-organic fertilizer: The standard implemented for bio-organic fertilizer is "Bio-organic fertilizer NY 884-2012".

When purchasing, be sure to look at the quality standards. Currently, my country's fertilizers only have these three standards, and there are no other standards. If there are other standards for microbial fertilizers, they must be conceptual hype, so choose carefully.

3. Look at the number of effective viable bacteria

The above product quality standards clearly stipulate that the effective viable bacteria of biological agents are ? 200 million/g (granules 100 million/g). The effective number of viable bacteria for compound microbial fertilizers and bio-organic fertilizers is 20 million/g. If you can't meet this requirement, don't choose. Some businesses falsely exaggerate the bacterial count for the sake of hype, so be careful.

4. Look at other elements of the packaging bag

In addition to the above important elements, the packaging bag must also have a clear production date, a clear trademark and product name, and a Clear functions and functions. In addition, the address and contact information of the manufacturer should also be clear to facilitate users to identify and contact. Finally, whether the outer packaging bag is damaged has also become an important inspection method.

5. Check the shelf life

Generally speaking, if the production date of microbial fertilizers exceeds one year, do not use it anymore. Not many effective bacteria of microbial fertilizers in my country can survive for more than one year. This also reminds us that the microbial fertilizer we bought should be used as soon as possible, and do not leave it for next year.

The above are some things you need to pay attention to when purchasing microbial fertilizers. Before purchasing microbial fertilizers, check the national implementation standards online before purchasing. In addition, grasp these five things to avoid being cheated. Bad businessmen cheating.
