In the market, the survival pressure of organic fertilizer enterprises mainly comes from three aspects: first, the extensive standard of organic fertilizer industry, the low threshold of investment in organic fertilizer machine
, which seriously restricts the development of market; second, the use effect of bio organic fertilizer is significant, the technical content is high, but there are many fake products in the market, so it is difficult to distinguish the true from the false; third, the market supervision of organic fertilizer is not in place, and the product type is not clear Most of the products are fake and confused.
So what is bio organic fertilizer?
refers to a special fertilizer with specific functional microbial strains. The product contains not only mature organic fertilizer, but also a specified number of functional bacteria. It is an organic unity of microbial fertilizer and organic fertilizer, belonging to the category of microbial fertilizer. Bio organic fertilizer is mainly used to resist soil borne diseases, promote root growth and improve fertilizer utilization.
It should be made clear that strains (bacterial agent, biological fertilizer, biological bacterial agent), compost, organic fertilizer (refined organic fertilizer, commercial organic fertilizer) are not biological organic fertilizer. The effect of bio organic fertilizer should be greater than that of the combination of high efficient bacteria (fungicide) and organic nutrition carrier.
Indicators of bio organic fertilizer
- CFU ≥ 200 million / g. Some products on the market are labeled with 2 billion or 200 billion effective bacteria / g, which are generally fake. " The number of effective viable bacteria (CFU) ≥ 200 million / g, and the successful colonization of functional bacteria, it is enough, not that the more the better.
- Organic matter content ≥ 45%. The nutritional basis for the growth, root colonization and function development of microbial species is formulated according to the research results and formula.
- Water content ≤ 30%. This is the necessary water content to ensure the survival of functional bacteria
