What is compound (mixed) microbial fertilizer

Compound (mixed) microbial fertilizer can be a compound product of multiple microbial groups, or a compound product formed by microbial groups, organic matter (livestock manure, peat, lignite, etc.), inorganic nutrients and other additives through fertilizer production process. The latter is commonly known as "Dasanyuan" microbial fertilizer.
Characteristics of compound (mixed) microbial fertilizer
1. Comprehensive effect
The formula design of compound microbial fertilizer fully considers the nutrient requirements of different crops, overcomes the disadvantages of single fertilization, integrates the "promotion" of microbial fertilizer, the "stability" of organic fertilizer and the "speed" of chemical fertilizer, and integrates the microbial, organic and inorganic components through the principle of scientific matching and complementary advantages, which can not only meet the nutrient requirements of crops, but also improve the soil structure It can also improve the quality of crops, reduce pests and diseases, so it is widely welcomed and praised by the market.
2. Coexistence of multiple components
In the process of fertilizer production, it is not easy to culture quick acting nutrients (fertilizer) with organic matter and specific living microorganisms. This is because inorganic nutrients are a variety of salts. If they exceed a certain concentration, the formed high osmotic pressure will analyze the water in microbial cells and cause microbial death. Simple mixing can not achieve the effective microorganism, inorganic nutrition and organic matter harmonious coexistence in the product.

One of the ways to choose is to select one or several kinds of spore bacteria with good resistance to adversity, and combine them with a reasonable process, so that the microorganisms before the combination are in a dormant state, and reduce or reduce the influence of bad conditions on the microorganism. After the product is applied into the soil, it will play the role of microbial fertilizer through spore germination. Another alternative is to separate granulation and film coating, that is, organic materials and microorganisms granulation together, inorganic nutrients granulation in addition, granulation and film coating at the same time, to minimize the impact of inorganic nutrients on microorganisms, film coating plays a slow-release role. The use of special technology ensures the synergy of the three components.
3. Adapt to a variety of plants
According to the characteristics of different crops and the ecological characteristics of different planting areas, the compound microbial fertilizer can adopt scientific and reasonable proportion, and then through the processing and manufacturing of organic fertilizer machine, after application, it can meet the requirements of sustainable development, reducing the amount of chemical fertilizer and the adverse impact on the environment.
