What happens if you fertilize too much fertilizer?

What happens if you fertilize too much fertilizer? Please introduce the following situations caused by excessive fertilization and chemical fertilizer: first, it will lead to a large yield-to-income ratio. First, limited by the level of farming and cultivation, crop fertilizer demand and other factors, crops can not get a very high yield; second, due to the excessive application of several kinds of fertilizers, resulting in nutritional imbalance, nutrient imbalance, only increase the cost but not increase the yield, and resulting in low-quality agricultural products are not easy to sell or the price is on the low side, bringing losses to farmers. Second, it leads to the decline of product quality. The partial application of certain chemical fertilizers leads to nutritional disorders of crops, hinders the transformation and synthesis of some substances in the body, and reduces the quality of products, such as melons and fruits are not sweet, vegetables are not delicious, and they are easy to rot and cannot be stored, all due to excessive application of chemical fertilizers. Third, lead to environmental pollution. Due to the application of too much chemical fertilizer, soil water-soluble nutrients and other substances were leached into groundwater and rivers by Rain Water and farmland irrigation, resulting in groundwater and river pollution in some areas and eutrophication of groundwater, rivers and lakes. As a result, the groundwater is not delicious, and fish and shrimp often die in some rivers and lakes. Fourth, it leads to the deterioration of soil properties. When a large amount of single element chemical fertilizer is applied in farmland, its nutrients can not be effectively absorbed and utilized by crops, and some chemicals such as nitrogen, phosphorus and potassium are easily consolidated by the soil, forming various chemical salts and accumulating in the soil, resulting in the imbalance of soil nutrient structure and the deterioration of physical properties. Harmful metals and harmful bacteria in some plots exceed the standard, resulting in the deterioration of soil properties. Click to get more compound fertilizer application techniques
