Rational application of organic fertilizer in vegetable garden
Organic fertilizer should not be applied excessively, as overuse can negatively impact the physical and chemical properties of the soil. In severe cases, it may lead to salt accumulation in the soil, which can hinder crop growth. Additionally, excessive organic fertilizer can cause nitrate buildup in vegetables, failing to meet the standards of modern vegetable production. When applying organic fertilizer in a vegetable garden, there are three key points to keep in mind:
First, choose high-quality organic fertilizer. The quality of the fertilizer directly affects the yield and quality of the vegetables. Using inferior organic fertilizer can actually harm the soil instead of improving it. It is best to use certified, large-scale produced organic fertilizers to ensure safety and effectiveness.
Second, control the application amount carefully. Normally, 15 to 20 cubic meters of pure chicken manure per mu of land is sufficient. For solanaceous vegetables that require more nutrients, you can go toward the upper limit, while leafy vegetables, which need less, should stay closer to the lower end.
Third, combine organic fertilizer with biological fertilizer. This combination helps improve nutrient availability. The beneficial bacteria in biological fertilizers can speed up the breakdown of organic matter, making it easier for plants to absorb nutrients. Moreover, they can also break down harmful substances present in the organic fertilizer, reducing the risk of damage to the vegetables.
By following these guidelines, farmers can maximize the benefits of organic fertilization while minimizing potential risks, ensuring healthier crops and sustainable farming practices.
