Ingredients and pretreatment: mix raw materials (such as sheep dung, chicken dung, straw, etc.) in a certain proportion, and add auxiliary materials (such as biogas residue, bone meal, cakes, etc.) as required to achieve different nutritional components and effects.

Fermentation: Adding bacterial strains to ingredients and mixtures for fermentation. During this process, the bacterial strains will decompose organic matter into nutrients that are more easily absorbed by plants. At the same time, a certain amount of heat and gas will be generated during the fermentation process. Therefore, it is necessary to use an organic fertilizer turner to turn the compost in a timely manner to ensure the smooth progress of the fermentation process.
Crushing: Fermented materials need to be crushed by an organic fertilizer crusher for subsequent processing and use.
Screening and post-processing: The crushed material needs to be screened to remove large particles and impurities to ensure product quality and uniformity. The screened material is then subjected to post-treatment using an organic fertilizer granulator, including adding trace elements, mixing evenly, drying, and sieving, to ultimately obtain qualified powdered organic fertilizer.
Packaging and sales: After the above treatment, the powdered organic fertilizer can be packaged and sold. The packaging materials should meet environmental requirements, and the packaging should indicate information such as the ingredients, efficacy, and usage of the product to facilitate user selection and use.
