As a new type of fertilizer, controlled-release fertilizer can not only improve the utilization rate of fertilizer, but also prevent environmental pollution. So, what is controlled-release fertilizer? What are the advantages of controlled-release fertilizer?

Organic-inorganic compound fertilizers are compound fertilizers that contain both organic matter and appropriate amounts of fertilizers? Strictly speaking, organic-inorganic compound fertilizers do not belong to organic fertilizers. They are a new type of fertilizer between organic fertilizers and inorganic fertilizers, and have the dual characteristics of organic fertilizers and inorganic fertilizers.

Advantages of controlled-release fertilizers:

Advantages of organic-inorganic compound fertilizers

1. Improve the absorption efficiency of nitrogen, phosphorus and potassium in the soil while supplementing soil organic matter

Organic-inorganic compound fertilizers contain both organic and inorganic components, so they combine the advantages of organic fertilizers and inorganic fertilizers. The fast-acting nutrients from inorganic fertilizers in the fertilizers are regulated by organic fertilizers, and the supply to plants is fast but not fierce; while the slow-acting nutrients from organic fertilizers can ensure the long-term supply of fertilizer nutrients. The combination of the two makes the fertilizer have the characteristics of both urgent and slow, balanced and stable, achieving the purpose of balanced and efficient fertilizer supply.

2. Improve the soil environment and increase the activity and reproduction of beneficial soil microorganisms

On the one hand, organic-inorganic compound fertilizers can adjust the soil pH value to a certain extent because they contain a certain amount of soil organic matter, so that the soil pH value is in a range that is conducive to the activation of most nutrients. Therefore, it can make the soil environment better.

On the other hand, since organic matter is the food of microorganisms, the addition of organic and inorganic fertilizers can enhance the activity of microorganisms in the soil, so that the complementary benefits of the two are enhanced, thereby further promoting the decomposition of organic matter and the activation of mineral phosphorus and potassium.
