People's misunderstandings about chemical fertilizer

As a result of years of farming and the use of chemical fertilizers, the soil hardening worsens, the nutrient elements are out of balance, the water quality is eutrophicated and the crop quality is declining, which makes people resist the food grown by chemical fertilizers and prefer crops from organic species. It makes sense.

In fact, all these are caused by unscientific and uncontrollable fertilization. Organic fertilizer and chemical fertilizer are as complementary as traditional Chinese and western medicine.

Organic fertilizer and chemical fertilizer are exactly the same in function, the ions decomposed are exactly the same, and the nutrient elements absorbed by plants are the same. They are all decomposed into the same ions before they are absorbed by plants. For example, organic fertilizers are slowly decomposed into nitrate ions, ammonia ions, phosphate ions, sulfate ions, potassium ions, calcium ions, copper ions, iron, zinc, manganese, magnesium, boron and molybdenum under the action of microorganisms, bacteria, fungi, actinomycetes, organic acids, etc. Chemical fertilizers are also decomposed into these ions before they are absorbed by plants. I do not know what is the difference in the nutritional composition of organic fertilizer and chemical fertilizer, which leads to everyone's resistance to chemical fertilizer, and producers cannot produce food without chemical fertilizer. Organic vegetables reject chemical fertilizers, but phosphate rock powder can still be used (phosphate fertilizer is also purified from phosphate rock, and its heavy metal content is less than phosphate rock powder.) Calcium chloride, these are also similar to chemical fertilizers. And there are many safety standards in the production of chemical fertilizers, such as the heavy metals in chemical fertilizers are not allowed to exceed the standards. Can other fertilizers do that? I think it is misleading that vegetables are delicious without chemical fertilizer.

The vegetables I produce with tap water and chemical fertilizer also feel very good, how can they be cleaner and hygienic than those irrigated by dung, and the harmful bacteria are much less? how can chemical fertilizer be blacklisted? It's kind of like talking about the color change of chemical fertilizer. In fact, as long as the amount of chemical fertilizer elements is controlled and applied according to the growth habits of crops, the vegetables produced are not worse than organic vegetables, or even better than organic vegetables.

Organic vegetables and hydroponic vegetables have their own advantages and disadvantages. The organic fertilizer applied by organic vegetables decomposes slowly, and it is greatly affected by the root system of crops. In addition to the natural degradation of organic fertilizer, plants will also decompose a lot of organic acids and other substances to decompose these organic substances for their own use. For example, crops need phosphorus, iron, and it will secrete a lot of organic acids to dissolve these substances. Or raise related bacteria, fungi and other related microorganisms to decompose organic matter. Therefore, crops have a certain selective control over the degradation of organic matter. What about hydroponics? Its nutrient elements are easily regulated by people to meet the needs of plant growth.
