The main reasons for choosing to use organic fertilizers include the following aspects:
1. Improving soil structure
Organic fertilizer increases soil organic matter content, promotes the formation of aggregate structure, and improves soil permeability and water retention capacity. Long term use can alleviate soil compaction, create a favorable environment for microbial reproduction, and activate soil biological activity.
2. Provide comprehensive nutrition
Organic fertilizers are rich in large amounts of elements such as nitrogen, phosphorus, and potassium, as well as trace elements such as calcium and magnesium. The release of nutrients is slow and balanced, avoiding abnormal growth of crops caused by excessive use of a single nutrient.
3. Improving crop quality and stress resistance
Organic fertilizer promotes the accumulation of sugar and flavor compounds in fruits, improving the taste and appearance of agricultural products. Meanwhile, beneficial microorganisms can inhibit pathogenic bacteria, enhance crop drought and cold resistance, and reduce pesticide dependence.
4. Environmental Protection and Sustainability
Compared to chemical fertilizers, organic fertilizers release nutrients more gently, reduce the risk of eutrophication in water bodies, and mitigate greenhouse effects through carbon fixation. Utilize agricultural waste (such as straw and livestock manure) to produce organic fertilizer and achieve resource recycling.
5. Economic benefits
Although organic fertilizers have slow short-term effects, long-term use can reduce the amount of chemical fertilizers used, lower production costs, and increase income by raising the selling price of agricultural products.
