Key Steps in Bio-organic Fertilizer Production
Bio-organic fertilizer is an eco-friendly agricultural input used to improve soil quality and boost crop yields; its quality depends entirely on a standardized production process. The production workflow consists of interconnected stages, with four core steps: raw material pretreatment, high-temperature composting/fermentation, granulation, and screening/packaging. Each step directly determines the fertilizer's viable microbial count, organic matter content, and ultimate field performance. Raw material pretreatment is the fundamental step in the production of bio-organic fertilizer . The primary raw materials—such as livestock manure, crop stalks, and agricultural waste—undergo sorting, impurity removal, and crushing to eliminate contaminants like stones and plastic. Next, the carbon-to-nitrogen (C/N) ratio and moisture content are adjusted; moisture is controlled at approximately 55% to ensure an optimal environment for microbial proliferation.
