This technology utilizes composted livestock and poultry manure, supplemented with plant-based residue fertilizers, to create a mixed organic fertilizer tailored to the nitrogen needs of green onions as outlined in the crop fertilization manual. While the composted manure mineralizes slowly, the faster-releasing plant residues ensure a steady nutrient supply throughout both the early and later growth stages, thereby reducing nutrient loss and overall fertilizer input. Furthermore, as green onion production is often severely affected by natural disasters due to climate change, the addition of plant growth promoters enhances seedling resilience under stress conditions.
