Green food (Grade A) can use chemical fertilizers in a timely manner
Appropriate application of chemical fertilizer can cultivate fertility and improve food quality. Fertilizers can supplement soil nutrients and balance crop nutrition to promote crop growth and improve the quality of agricultural products. The nutrient that crops draw from fertilizers is exactly the same as that of the same nutrient elements extracted from organic fertilizers. Whenever the decline in food quality is blamed on the use of chemical fertilizers, this is actually a misunderstanding. There are essential differences between fertilizers and pesticides in affecting food quality. Chemically synthesized pesticides are generally different from natural products. They are organic substances that do not exist in the natural environment. Some components can accumulate in humans and animals. Some components may cause cancer. Some components may remain in the soil for a long period of time and participate in the ecological cycle. Negative effects are greater. Fertilizers are different from pesticides. The composition of chemical fertilizers is found in natural soils. Fertilizers are used to supplement the plants and the soil supplies insufficient nutrients. When this year's major fertilizer varieties, some of them come from the transformation of natural minerals, such as phosphate fertilizer, potassium fertilizer, nitrogen fertilizer is synthetic ammonia and its processed products. In fact, organic matter in organic fertilizers cannot generally be directly absorbed by crops, but must be decomposed into the same ingredients as in chemical fertilizers before they can exert their nutritional effects. The relationship between chemical fertilizers and food quality is relatively close, and it can be concluded that the proper application of chemical fertilizers is beneficial, and improper application is harmful. Phosphorus and potash fertilizers have a significant role in promoting the quality improvement of agricultural products. Taking potassium from vegetables as an example, potassium can reduce the nitrate content in vegetables, increase the uniformity of vegetables, enhance disease resistance, and improve quality. Potassium application can increase the sugar content of watermelon, reduce the acidity, and increase the storage resistance. Potassium promotes the transfer of amino acids to the grain and facilitates the synthesis of protein in the grain. Appropriate use of nitrogen fertilizer can also improve quality. In the production practice, the main problems in the application of chemical fertilizers are the imbalance of nutrients, the excessive use of nitrogen fertilizer, the shortage of potassium fertilizer and trace elements. The deterioration of permeability, loss of nutrients, pollution of the environment, resulting in the increase of nitrate nitrogen and nitrite nitrogen in the water, and nitrate enrichment in agricultural products, harming human health.
