Simple Process to make slow release granular fertilizer

The good application effect of chemical fertilizer largely depends on its physicochemical state. For example, the active component phosphoric acid in calcium superphosphate is the state of calcium phosphate. Soluble in water and can be completely absorbed by plants. However, just because it is a quick acting fertilizer, plants often lose part of it before they can fully absorb it.

In addition, the phosphorylation energy of calcium superphosphate and impurities in soil can not absorb and utilize compounds such as iron phosphate and aluminum phosphate. The smaller the powder of calcium superphosphate, the larger the contact area with soil. Therefore, the greater the amount of compounds that cannot be absorbed by impurities in the soil, the more fertilizer loss. Need machines to make slow release fertilizer granules?

Because the physical state of slow-release granular fertilizer is solid particles, the above shortcomings can be avoided, nutrient loss can be reduced and fertilizer efficiency can be prolonged. Therefore, in the process of fertilizer manufacturing, the treatment of granulator is very necessary.

Granulation equipment is the most commonly used granulation equipment in the manufacturing process of granular fertilizer

Disc granulator is a well-known fertilizer granulation equipment. The whole is in a swashplate shape. The powdery materials roll in the plate with the bottom of the plate, and the materials adhere to each other to form spherical particles after being affected with moisture. The principle of the granulator is like a snowball. It depends on the viscosity of the material itself to bond and grow.

When the particles grow to a certain extent, they will come out of the plate and enter the next processing process. If the particle size requirements cannot be met, it shall remain in the pan and continue granulation until the requirements are met.

The drum granulator also adopts a similar granulation principle, but the disc granulator is an open structure and the drum granulator is a cylinder, but both are the principle of continuous combination of powdery materials with the help of water.

Granular fertilizer with appropriate particle size. Drum granulator has a wide range of raw materials and can produce organic fertilizer, compound fertilizer and other fertilizers.

Microbial fertilizer basis

Microbial fertilizer is a kind of biological preparation containing living microorganisms. It can obtain specific fertilizer effect in use and improve plant yield or quality.

1. Increase crop yield

The growth rate of microbial fertilizer is about 10%, and the yield of compound microbial fertilizer is the most obvious, reaching more than 20%. The results showed that the application of microbial fertilizer alone without fertilization, organic fertilizer or chemical fertilizer had a significant impact on potato yield, but microbial fertilizer only played an auxiliary role in crop yield and could not replace the use of organic fertilizer and chemical fertilizer alone

2. Improve crop quality

It is an indisputable fact that microbial fertilizer can improve crop quality. Some microbial fertilizers can improve crop quality even if there is no significant increase in yield. The application of microbial fertilizer can significantly increase the content of sugar and vitamin C in vegetables and reduce the content of nitrate in vegetables.

The effect of microbial fertilizer on fruit quality was also obvious. The results showed that in the use of microbial fertilizer, the nitrogen content of Dangshan pear leaves decreased significantly, the content of trace elements decreased significantly, and the sugar acid ratio, sugar content and Vc content increased significantly, which proved that the quality and grade of fruit quality and storability pear were significantly improved.

3. Reduce diseases and insect pests

The results showed that microbial fertilizer had stable control effect on Cotton Fusarium Wilt and Eggplant Verticillium wilt, and the disease index decreased to 38.2 and 23.5 respectively. Special microbial fertilizer for tobacco can reduce tobacco virus disease, promote tobacco growth, reduce gas and irritation. Microbial fertilizer can effectively reduce the damage of residual herbicides in soil to crops.

4. Improve soil structure

Long term application of microbial fertilizer can restore the formation of soil aggregate structure, loosen soil, eliminate soil hardening and improve soil structure.

It is reported that in the cold black soil of northern China, soil phosphorus activator has been applied for 3 years. The soil bulk density decreased by 0.1 ~ 0.3, and the soil loosening effect was very significant.

Some studies have also shown that the application of microbial fertilizer can promote the release of soil organic matter, improve soil physical and chemical properties, increase soil aggregates and improve soil structure due to the massive reproduction of microorganisms.
