In decades of years, inorganic fertilizer has been in large-scale application and dominates the fertilizer market. It is considered the most basic and important material input of agricultural production. However, inorganic fertilizer is long been debated for its bad influence on soil and environment. Excessive use of inorganic fertilizer makes the organic matter in soil gravely insufficient, the soil will harden and its water permeability, air permeability and light absorption will deteriorate, threatening the land quality and ecological environment. Meanwhile, organic fertilizer, as a favorable alternative, has a slow efficiency, exclusive use of it can’t meet the requirement of crops. In this case, organic-inorganic compound fertilizer has come into view.
Organic-inorganic compound fertilizer uses organic materials such as manure and humic acid as raw material, after microbial fermentation, inorganic fertilizers are added as per certain proportion, and then by granulating, the organic-inorganic compound fertilizer is formed. It has the following benefits.
1. Balanced Nutrient Supply
Organic compound fertilizers not only can realize the balance of nitrogen, phosphorus and potassium nutrients like inorganic compound fertilizer, it can also achieve the equilibrium of organics and inorganics. By the regulation of organic fertilizer, the rapidly available nutrients in the inorganic fertilizer will be supplied not too fast, while the slowly available nutrients in the organic fertilizer will ensure the lasting supply of nutrients, meeting the nutrients requirement of the whole growth period of the crops, increasing the yield and improving the quality.
2. High Using Efficiency
The inorganic composition that otherwise could easily flow away with rain, can be attached on the organic composition effectively, and absorbed continuously later by the crops, reduce the loss of inorganic composition. Meanwhile, organic matter makes the phosphorus in the compound fertilizer not easy to be fixed as in inorganic phosphate fertilizer, increasing the using efficiency.
3. Improve Soil Property
Organic-inorganic fertilizer contains large amount of organic matter, which can improve the physicochemical property and biological property of the soil.
4. Activate Soil Nutrients
On one hand, Organic-inorganic compound fertilizer can strengthen microbial activity in soil, promote the decomposition of soil organic matter, release nitrogen, phosphorous and trace element, make the mineral form of phosphorous, potassium and silicon available. On the other hand, organic-inorganic compound fertilizer can regulate the soil PH value to some extent, make it beneficial for the activation of most nutrients.
5. Physiologic Regulation
The organic-inorganic compound fertilizer contains quite a large amount of physiological activator, such as amino acid, humic acid, and enzymes, they can promote root respiration, absorption of nutrients and leaf photosynthesis, etc.
We supply no-drying extrusion compound fertilizer production line that can produces organic-inorganic compound fertilizer. It doesn’t need heat and humidify materials, adapts to the thermal sensitive resistance material, no waste-water and waste-gas discharge. The raw materials are put into mixing machine first. Then the conveying belt sends the materials to disc feeding machine, and go into the extrusion granulating machine next. The slices coming out from granulating machine will go through the primary crusher and then be conveyed to screening machine by belt conveyor. The qualified materials can be sent to packaging machine, while others are conveyed back to the disc feeding machine to be re-processed. Our compost turner for organic material fermentation is in hot sell.
