The applications of organic fertilizer granulation are very extensive, mainly reflected in the following aspects:
Provide plant nutrition
After granulation, organic fertilizer contains abundant nutrients such as nitrogen, phosphorus, potassium, as well as trace elements such as iron, zinc, copper, manganese, and boron, which are essential for plant growth. Granular organic fertilizer can provide comprehensive and balanced nutrition for plants, promoting healthy plant growth.
Improve soil structure
After granulation, organic fertilizer can increase the organic matter content of soil, improve the particle structure of soil, and enhance the soil’s water and fertilizer retention capacity. At the same time, beneficial microorganisms in organic fertilizers can decompose organic matter in the soil, release nutrients that plants can absorb, and inhibit the growth of pathogenic microorganisms, further improving the soil environment.
Improve crop quality
Long term use of granular organic fertilizer can improve crop quality, such as increasing fruit sweetness, improving taste and nutritional value. This is because the nutrients in organic fertilizers can be supplied more evenly to plants, enabling them to better carry out photosynthesis and material accumulation.
Environmentally friendly and sustainable
The production and use process of organic fertilizer granulation is relatively environmentally friendly, which helps reduce the use of chemical fertilizers, alleviate environmental pollution, and promote sustainable development of agriculture. The raw materials for granular organic fertilizers usually come from animal and plant waste, food processing waste, etc. Through granulation treatment, waste can be reused and resource waste can be reduced.
Convenient for application and storage
Granular organic fertilizer has the advantages of good breathability, low moisture absorption and clumping, and easy storage and transportation. Compared with traditional farmyard manure, granular organic fertilizer is easier to apply and can be evenly spread in the field by mechanical or manual means to improve fertilization efficiency.
Improve fertilizer utilization efficiency
The nutrient release rate of granular organic fertilizer is moderate, which can avoid rapid loss or soil fixation of nutrients, thereby improving the utilization efficiency of fertilizer. Meanwhile, microbial activity in granular organic fertilizers can also promote the transformation and release of soil nutrients, further improving the efficiency of fertilizer utilization.
In summary, organic fertilizer granulation not only provides basic functions such as plant nutrition, improving soil structure, and enhancing crop quality, but also has advantages such as environmental sustainability, convenient application and storage, and improved fertilizer utilization efficiency. Therefore, granular organic fertilizer has broad application prospects and promotion value in agricultural production.
