Organic Fertilizer Use Precautions
In use, the choice of high-quality organic fertilizer is undoubtedly the most important, but also need to pay attention to the following points:
- The nutrient content of organic fertilizer is not balanced, the content of nitrogen, phosphorus and potassium is low, and the decomposition in soil is slow. Although there are many nutrients, it can not meet the needs of high yield and quality of crops if not applying the chemical fertilizer without single nutrient. When applying organic fertilizer, the fertilizer should be applied according to the requirements of the crop for nutrients, and the organic fertilizer and fertilizer should be applied together to make up for each other’s strengths, and to meet the needs of various nutrients in the quantity and time. Even the farmland that produces green food should be supplemented with appropriate amount of mineral fertilizer, and spray the biostimulant high-quality foliar fertilizer during the growth of the crop to ensure the nutritional needs of the crop.
- Organic fertilizer should not be mixed with alkaline fertilizer to avoid ammonia volatilization and reduce nutrient content of organic fertilizer. Organic fertilizers contain more organic matter and should not be mixed with nitrate nitrogen.
- Do not use organic fertilizer excessively. Excessive use of organic fertilizer can lead to the following conditions: burning seedlings, causing a large concentration of nutrients such as phosphorus and potassium in the soil, resulting in imbalance of soil nutrients; nitrate ions in the soil accumulate, causing the nitrate salt of the crop to exceed the standard, and the concentration of the soil solution is high, Conducive to root water absorption.
