Answer: Raw materials for organic fertilizer production are diverse and eco-friendly, falling mainly into four categories: livestock and poultry manure, agricultural waste, plant-based oil cakes, and mineral additives; these constitute the core ingredients for high-quality organic fertilizer. Livestock and poultry manure—including cattle, sheep, chicken, and pig manure—is rich in organic matter and N-P-K nutrients, offering long-lasting fertilizing effects; it serves as a fundamental base material that effectively improves soil fertility. Agricultural waste includes crop stalks, rice husks, peanut shells, spent mushroom substrate, sawdust, and sugarcane bagasse; characterized by a loose texture and high carbon content, these materials are primarily used to adjust aeration, facilitate thorough fermentation and decomposition, and alleviate soil compaction. Plant-based oil cakes—such as soybean, rapeseed, and peanut cakes—are high-quality, nutrient-rich ingredients that decompose easily; they significantly enhance the quality of the final product and are frequently used in the production of premium organic fertilizers. Additionally, auxiliary materials like peat and humus help activate the soil and improve its water and nutrient retention capabilities. All raw materials must undergo high-temperature decomposition to eliminate pathogens and insect eggs and remove harmful substances; this prevents issues such as crop burn or pest and disease outbreaks after application, ensuring the fertilizer is safe, compliant with standards, and suitable for a wide range of fruits, vegetables, and crops.
