In the wave of green transformation in agriculture, organic fertilizer, with its eco-friendly characteristics, has become a key tool for soil improvement and quality enhancement. Advanced production technologies provide the core impetus for its large-scale, high-quality development, demonstrating irreplaceable technological advantages.
Innovation in raw material processing technology is the primary breakthrough in organic fertilizer production.Traditional composting suffers from problems such as low raw material utilization and impurity residue. Modern technology, through processes such as crushing and screening, high-temperature sterilization, and heavy metal passivation, enables the efficient conversion of raw materials such as agricultural and forestry waste and livestock and poultry manure into organic fertilizer making process. For example, intelligent crushing equipment can refine fibrous raw materials such as straw and dead branches to the millimeter level, significantly increasing the fermentation contact area; high-temperature aerobic fermentation technology can stabilize the material temperature at 55-65℃, continuously killing insect eggs, pathogens, and weed seeds. Simultaneously, through the addition of microbial agents, over 90% of the organic matter in the raw materials is converted into effective nutrients, solving the pain points of traditional composting being "dirty, smelly, and impure."
Nutrient regulation technology enables "precise matching" of organic fertilizer. Through nutrient testing and formulation optimization technologies, producers can precisely adjust the proportions of nitrogen, phosphorus, potassium, and micronutrients according to different crop needs and soil fertility conditions to create customized organic fertilizer products. For example, to address the high fertilizer requirements of greenhouse vegetables, an "organic-inorganic composite technology" is used, scientifically blending slow-release chemical fertilizer components into organic fertilizer. This retains the soil-improving advantages of organic matter while meeting the nutrient supply needs of crops during their growth period. Meanwhile, humic acid extraction and activation technology enhances the water and fertilizer retention capacity of organic fertilizer, increasing nutrient utilization by over 30%.
Environmentally friendly and emission-reduction technologies highlight ecological advantages. Modern organic fertilizer production utilizes technologies such as closed fermentation tanks, biological deodorization systems, and wastewater recycling to achieve zero pollutant emissions during the organic fertilizer production process. The closed-loop fermentation process collects the biogas produced during fermentation and recycles it as clean energy. The combination of biofilters and activated carbon adsorption effectively removes odorous gases such as ammonia and hydrogen sulfide, achieving a purification efficiency of over 95%. Fermentation wastewater, after sedimentation and filtration, is recycled for wetting the raw materials, realizing water resource recycling and making the entire organic fertilizer production process green and environmentally friendly.
The in-depth application of modern technology has enabled a qualitative leap in organic fertilizer production. These technological advantages not only improve the product quality and production efficiency of organic fertilizer but also provide strong support for ensuring food security and improving the ecological environment.
