Farmers are very anxious to report to the relevant departments of industry and commerce and agriculture. Through the inspection of the agricultural technology department, it is found that this “ecological fertilizer†is actually a category of organic and inorganic compound fertilizers. The nutrient content is in line with the labeling of its packaging bags, but the enterprises are unconventional, Therefore, it is novel, adding some acidic substances, so that the pH of this "ecological fertilizer" is 3.0, and the pH value is so low that the property of the fertilizer is a very acidified organic-inorganic compound fertilizer. Its acidification has surpassed the common common large fertilizers and organic fertilizers. For example, ammonium sulfate, ammonium chloride, potassium chloride, etc. are all neutral salts, which are physiologically acidic after being applied to the soil and then absorbed by the crop.

At present, although the development speed of new fertilizers in China is very fast, it is necessary to let the new fertilizer market develop healthily, let the farmers see the advantages of new fertilizers, accept and apply new fertilizers, and still have a long way to go in production, sales and service. To this end, please don't just use some novel fertilizer names to fool farmers' consumers. Farmers need to look at the facts and see the real fertilizer effect. Especially the advertising of new fertilizers should be worthy of the name. The performance of the products should be true. The supporting methods should be specific. Names and labels must be reasonable and legal. Although some false propaganda is now profitable, it will not be recognized by farmers for a long time, and it is untenable in the market.
The fertilizer industry plays an important supporting role in China's food security. No matter the production, sales or supervision personnel, whether it is experts, scientific and technical personnel or farmers, the complex fertilizer market must be re-recognized repeatedly. “Fertilizer†is an essential attribute of important agricultural production materials. It is an organic or inorganic substance used to supply essential nutrients to crops. It does not need and should not impose more “functions†on fertilizers.
