The processing of organic fertilizers has significantly driven agricultural development. The processing technology involves the commercialization of composted materials. By utilizing organic fertilizer equipment and control technologies to produce high-value, commercialized organic fertilizers, the process achieves resource recycling. During this production process, aerobic composting technology is required to ferment and degrade waste materials. Today, we will explain the aerobic composting technology used in organic fertilizer equipment:
The principle behind high-temperature, rapid aerobic composting is essentially the microbial decomposition of organic materials. Through this microbial action, organic matter is broken down into small-molecule fulvic acids, unavailable nutrients are converted into accessible nitrogen, phosphorus, and potassium, and large-molecule proteins are transformed into small-molecule amino acids. This is a process of organic matter transformation. Simultaneously, the composting material accumulates significant heat, raising the pile temperature to over 60°C. Maintaining this temperature for a certain period effectively kills pathogens and weed seeds, achieving the harmless treatment of the compost. During the subsequent low-temperature curing (aging) phase, microorganisms reproduce gently and continue to decompose the organic matter. Throughout this reproduction and decomposition process, they secrete abundant biostimulants, which enhance both the quality and fertilizer efficiency of the organic product.
The goal of aerobic composting is to reduce volatile substances and odors in the waste, and to eliminate parasite eggs and pathogenic microorganisms, thereby achieving harmless treatment. Additionally, the composting fermentation process reduces the moisture content of the organic materials, decomposes and mineralizes the organic matter to release nutrients such as N, P, and K, and makes the material looser and more dispersed, which facilitates storage and application.
After the primary aerobic composting phase, solid organic waste has not yet fully matured and requires a secondary fermentation stage, known as curing. The purpose of curing is to further decompose and stabilize the remaining large-molecule organic matter, as well as to dry the material, ensuring it meets the requirements of subsequent fertilizer manufacturing processes.
