Crop straw is a common waste in agricultural production, but in the field of organic fertilizer granulation, it has become a valuable renewable resource.

Wheat straw is rich in organic substances such as cellulose, hemicellulose, and lignin. After being crushed, these straw fragments become a good base material for organic fertilizer granulation. Through microbial fermentation, the organic matter in straw gradually decomposes and transforms, releasing nutrients such as nitrogen, phosphorus, and potassium. In this process, adding appropriate amounts of other nutrients and biological agents, and then using an organic fertilizer granulator for processing, can produce organic fertilizers rich in various nutrients and with soil improvement functions.

Corn stover is also a high-quality raw material choice. Corn straw has a relatively high carbon and nitrogen content. During the fermentation process, microorganisms utilize the carbon source in the straw for growth and reproduction, while fixing the nitrogen in the surrounding environment, thereby increasing the nitrogen content in the fertilizer. After fermentation and maturation, corn stover is pressed into granules by an organic fertilizer granulator, which is not only convenient for storage and transportation, but also can slowly release nutrients after being applied to the soil, providing long-term fertility support for crops.

Rice straw also has unique advantages. It contains a certain amount of silicon element, which has a positive effect on improving the lodging resistance and disease resistance of crops. Pre treat rice straw to fully soften and decompose it, then mix and ferment it with other organic materials, and use an organic fertilizer granulator to process it into granular fertilizer. After being applied to farmland, this fertilizer can increase the silicon content of the soil, improve the physical properties of the soil, and promote the healthy growth of crops.

In addition to common grain crop straw, some economic crop straw such as cotton straw, rapeseed straw, etc. can also be used for organic fertilizer granulation. These straw also contain abundant organic matter and minerals, and after reasonable treatment, they can become raw materials for producing high-quality organic fertilizers.

As a raw material for organic fertilizer granulation, crop straw not only realizes the resource utilization of agricultural waste, reduces environmental pollution, but also provides a sustainable source of fertilizer for agricultural production. By processing with organic fertilizer granulators, these straw can be converted into efficient organic fertilizers, which helps promote the development of green agriculture.
