Fertilizer raw materials are like the building blocks of tall buildings, providing indispensable nutrients for the healthy growth of crops. Among the many fertilizer types, organic fertilizer is favored for its natural, environmental protection and sustainable characteristics. The Organic fertilizer production process is inseparable from carefully selected fertilizer raw materials and exquisite organic fertilizer production technology.

The variety of fertilizer raw materials provides a broad choice space for the production of organic fertilizer. Common organic fertilizer raw materials include livestock manure, crop straw, green manure, cake meal, humic acid and so on. Animal manure is rich in nitrogen, phosphorus, potassium and other nutrients, which is one of the important raw materials for organic fertilizer production. However, untreated livestock and poultry feces may contain harmful substances such as germs and eggs, which need to be treated by fermentation and other processes before they can be safely used.
Crop straw is the waste in agricultural production, but after grinding, fermentation and other treatment, it can be transformed into high-quality organic fertilizer raw materials to achieve the recycling of resources. Green manure is produced by planting specific plants, absorbing nutrients from the soil during their growth, and then ploughing them into the soil to provide rich organic matter and nutrients for the soil. Cake meal is a by-product of oil extraction from oil crops, which contains high protein and organic matter, and is also a high-quality raw material for organic fertilizer production. Humic acid is a kind of organic substance widely existing in nature, which has the function of improving soil and improving soil fertility.
Organic fertilizer production process is the key link to convert these fertilizer raw materials into high-quality organic fertilizer. The first is the collection and pretreatment of raw materials. At this stage, various fertilizer raw materials need to be collected, sorted and initially treated. For example, the manure of livestock and poultry is dried and dried to remove water from it; Crop straw is pulverized to increase its surface area and facilitate the subsequent fermentation process. This is followed by the fermentation phase, which is the core step of organic fertilizer production.
By adding starter, controlling temperature, humidity and ventilation, the decomposition and decomposition of organic matter in fertilizer raw materials are promoted. During the fermentation process, microorganisms decompose large molecular organic matter into small molecular organic matter, while generating heat, killing bacteria and eggs in it, making organic fertilizer safer and more efficient. After fermentation is complete, post-treatment is also required, including drying, sieving, granulation and other steps. Drying can remove excess water in organic fertilizer and improve its storage stability. Screening can classify organic fertilizers of different particle sizes to meet the needs of different users; Granulation can make organic fertilizer more beautiful and easy to apply.
Fertilizer raw materials are the cornerstone of organic fertilizer production, and organic fertilizer production processes are the key to converting these raw materials into high-quality organic fertilizers. In the future agricultural development, we should pay more attention to the selection and utilization of fertilizer raw materials, constantly innovate and improve the production process of organic fertilizer, and provide more powerful support for the sustainable development of agriculture.
