Is chemical fertilizer harmful to human body?

Chemical fertilizer is harmful to human body.

Nitric acid in fertilizer will be reduced to nitrite by human bacteria, and nitrite is a carcinogen, which will cause cancer. There are too few "green foods" in China's three meals. Fertilizer has become the biggest potential killer in our food structure, and it is difficult for us to get rid of it. Long-term accumulation in the body will form toxins.

According to the law of crop fertilizer demand, soil fertilizer supply performance and fertilizer effect, the suitable dosage and proportion of various fertilizers and the corresponding fertilization methods were put forward under the condition of organic fertilizer as the main factor.

Popularizing formula fertilization technology can determine the quantity, type and period of fertilization, which is beneficial to the balanced supply of soil nutrients, reduce the waste of chemical fertilizers and avoid pollution to the soil environment.

Extended data:

Long-term application of chemical fertilizer accelerates nitrification of soil acidification nitrogen fertilizer in soil to produce nitrate. Firstly, ammonium is converted into nitrite, and then nitrite is converted into nitrate, forming H+, which leads to soil acidification.

Some physiological acid fertilizers, such as calcium phosphate, ammonium sulfate, ammonium chloride, etc., increase H+ in soil after plants absorb nutrient ions from fertilizers. Acidification of many cultivated soils is related to long-term application of physiological fertilizers.

At the same time, long-term application of kcl, due to the physiological acidity caused by selective absorption of crops, can make neutral soil with small buffer gradually sour.
