Are there so many "revolutionary products" fertilizers?

I just searched online for "fertilizer+revolutionary products", and sogou has found about 13407 related results for me. This makes me wonder, has our fertilizer technology really developed so fast in recent years?

As we know, since 1809 discovered the sodium nitrate deposit in Chile, South America, German chemist Haber applied for a patent for synthetic ammonia by recycling method in 1908. In the history of nitrogen fertilizer for more than 200 years, our nitrogen fertilizer has less than 20 products, such as ammonia water, ammonium carbonate, ammonium sulfate, monoammonium phosphate, diammonium phosphate, potassium nitrate, calcium nitrate, magnesium nitrate, sodium nitrate, ammonium nitrate (generally not used as fertilizer), urea, urea phosphate, ammonium nitrate urea and so on. That is to say, on average, less than one revolutionary product appeared in ten years.

1908, Russian scholars put forward the viewpoint that phosphate fertilizer can be decomposed with nitric acid to produce fertilizers containing N and P. 1927, Germany, Germany, France and Germany first decomposed phosphate rock with mixed acid of nitric acid and phosphoric acid, and then added potassium salt to the acid hydrolysis product to obtain fertilizers containing N, P and K comprehensive nutrients. 1928 The Norwegian Oda Smelting Company proposed a method of decomposing phosphate rock with nitric acid. The obtained acidolysis solution was frozen to separate most calcium nitrate, and then processed into fertilizer. Up to now, it is dozens of products such as calcium superphosphate, monoammonium phosphate, diammonium phosphate, potassium dihydrogen phosphate, urea phosphate, pyrophosphate, polyphosphate and phosphoric acid. Potassium fertilizer, only potassium sulfate, potassium chloride, potassium nitrate, potassium dihydrogen phosphate, potassium humate and other products.

Yes, there are too many related results in13,407 in recent years.

I cut some pictures from the first page of the search results. You can have a look.

Then I'll see if the top three products are revolutionary products.

(1) Organic Carbon Fertilizer-Revolutionary Theory of Fertilizer: I found the Concept of Biological Humic Acid and Organic Carbon Fertilizer edited by Li Ruibo and Wu Shaoquan and published by Chemical Industry Press. This book is introduced as follows: "This book focuses on biological humic acid organic carbon fertilizer, discusses traditional chemical plant nutrition and soil fertilizer science, and puts forward the idea of building a" harmonious "fertilizer industry and fertilization policy. This book is very suitable for people engaged in the research, development, production and use of humic acid, and can also be used as a reference for agricultural managers, agriculture, fertilizer industry, environmental protection industry and other personnel in government departments at all levels. "

So is organic carbon a revolutionary product?

Confining humus in soil is a theory that can be used as plant nutrients. This was put forward by German Mu Zi at the end of18th century. This statement is wrong. It has been rejected by German chemist Justus von Liebig's "Plant Mineral Nutrition Theory".

In addition, Ukrainian-American biochemist and soil microbiologist Wachsman. 19 13 years, he found actinomycetes in soil 19 17 years, and he found that the decomposition of soil organic matter was related to microbial enzymes. In the 1920s, he clearly pointed out that soil humus is the semi-decomposition product of animal and plant residues under the action of soil microorganisms, which is conducive to improving soil structure and providing nutrition for plants. He also improved the method of analyzing and separating soil humus.

Therefore, organic carbon fertilizer is not a revolutionary product, but a combination of humic acid theory and modern industrial products (especially the recycling of industrial waste), which can not be regarded as a revolutionary product of fertilizer industry.

(2)- "Feiyue soil conditioner: the revolutionary product of soil conditioning and the leader of alkaline fertilizer!" Shandong Feiyue Chemical Fertilizer Co., Ltd. is a new pearl of chemical fertilizer industry in China. After reading his product introduction, I can directly say that revolutionary products are not revolutionary, and revolutionary changes are not even counted!

(3) The new chemical fertilizer echoes the supply-side reform, and Batian shares push revolutionary products again. This is more reliable than the previous one, but it is far from revolutionary products. I have carefully read this technology, and there is a breakthrough, but it can only be a technological innovation, not a fertilizer revolution!

Therefore, regarding the revolutionary products in the chemical fertilizer industry, I want to make a rumor: there are not so many revolutionary products. If the application and technical services are done well according to local conditions, farmers will have many changes, even the transformation of fertilization methods. There are not so many revolutionary fertilizers. It is not so much a revolutionary product as an innovation in fertilization technology and extension service mode.

Finally, I appeal to everyone! Fertilizer products and fertilization technology need innovation and change according to local conditions, but don't upgrade everything to revolutionary products! Farmers don't have so much professional knowledge, please be entrepreneurs with conscience!
