Many people know that organic fertilizer is a "great helper" for improving soil and increasing yields, but few understand that these bags of nourishing fertilizer are actually "transformed" from waste materials around us. From crop residues and livestock manure in the fields to fruit peels and vegetable scraps from our daily lives, through a scientific and standardized processing procedure, these seemingly useless wastes can be transformed into natural nutrients that nourish crops, achieving a green cycle of "turning waste into treasure."
The first step in the creation of organic fertilizer is "collecting raw materials." The sources of these raw materials are very diverse: corn stalks and wheat straw after harvesting in the fields, cow, sheep, and pig manure from farms, and even discarded rotten vegetable leaves and fruit peels from the market are all high-quality raw materials for making organic fertilizer. Workers first perform a simple cleaning of these raw materials, removing stones, plastics, and other impurities to avoid affecting subsequent processing and fertilizer quality.
After the raw materials are prepared, the most crucial step is "fermentation and maturation," which is the core difference between organic fertilizer and unfermented waste. Workers mix the cleaned raw materials in appropriate proportions, add special fermentation strains, and pile them into heaps 1.5 to 2 meters high. Then, they use a compost turning machine to regularly turn the piles, controlling the temperature of the piles between 55 and 65℃. This temperature kills pathogens and insect eggs in the raw materials and allows the fermentation strains to fully function, breaking down large molecules in the raw materials into nutrients that are easily absorbed by crops. After 7 to 10 days of fermentation, the originally pungent odor gradually dissipates, and the color of the raw materials turns dark brown, feeling soft to the touch, indicating that the maturation process is complete.
After fermentation, the process enters the "processing and shaping" stage, where granulation is one of the key steps. The matured raw materials are first sent to a crusher for crushing, and then filtered through screening equipment to remove incompletely fermented particles, ensuring that the fertilizer is uniform in texture and free of impurities. Subsequently, the qualified raw materials are sent to a granulator, where an appropriate amount of binder is added as needed. Through extrusion and rolling, the loose powder raw materials are made into uniformly sized granules. Granulation not only makes organic fertilizer easier to store and transport, preventing it from being blown away by the wind during application, but it also slows down the release rate of nutrients, extending the fertilizer's effectiveness and allowing crops to continuously absorb nutrients. After granulation, the granules are dried to control the moisture content to below 15%, preventing clumping and mold.
The final step is "quality inspection before shipment." Staff members conduct random sampling and testing of the processed organic fertilizer, checking indicators such as organic matter content, moisture content, and pH value to ensure compliance with national organic fertilizer standards and the absence of harmful components. After passing the inspection, the organic fertilizer is packaged and sealed by a packaging machine and transported to farms across the country, becoming a natural nutrient source for nourishing crops and improving soil.
From waste to organic fertilizer, every step embodies the concept of green environmental protection. It not only solves the problem of waste disposal and reduces environmental pollution, but also improves soil structure and enhances crop quality, making farmland more fertile and agricultural products safer, using the power of nature to protect the sustainable development of agriculture.
