Some farmers like to buy "three 15" compound fertilizer. Why are some manufacturers unwilling to produce?

"Three 15" refers to compound fertilizer with nitrogen, phosphorus and potassium content of 15% and total content of 45%. At present, the "35" compound fertilizer is hard to find, and it has been replaced by several mixed fertilizers and special fertilizers.

Some people think that "three 15" as a general compound fertilizer has two main disadvantages: first, serious homogenization, transparent price, meager income and insufficient motivation for dealers. Second, the fertilizer itself does not meet the requirements. Basic requirements of crops for fertilizers and scientific fertilization. Is that really the case? On March 26th, the launching ceremony of "20 17 Structural Reform of Fertilizer Supply Side" was held in Beijing. Bai, chairman of China Institute of Nutrition and Plant Fertilizer, said that the fertilizer industry should first distinguish between suppliers and suppliers. From the perspective of the whole industry, fertilizer homogenization is not a problem in supply. This is a competitive problem in the fertilizer market.

Bai said that the problem of fertilizer supply is what kind of fertilizer is needed for agricultural production in China, but our fertilizer industry can't produce it, or the fertilizer industry can't meet the needs of agricultural production. In China, it must be imported. Secondary problems At present, in addition to potash fertilizer, there is also the problem of overcapacity in China's fertilizer industry. The nitrogen fertilizer industry and the phosphate fertilizer industry are all losing money, but why China still imports a lot of chemical fertilizers, and agriculture prefers to import chemical fertilizers, which is worth thinking about.

Bai said that the reform of fertilizer supply in China needs innovative fertilizers. Fertilizer innovation must start from the following aspects: First, innovative concentration: increasing the concentration of nutrients in fertilizers is the trend of international fertilizer development in recent decades. At present, people pay attention to fertilizers mainly because the ingredients in fertilizers are unknown. Fertilizer components for agricultural product quality, soil health and environmental safety. Uncertainty, in the case of low concentration, many components are unclear, and the potential risk is terrible. Therefore, increasing the concentration of fertilizer is one of the problems facing the fertilizer industry. The second is the proportion of nutrients in fertilizer. When soil testing and formula fertilization began in 2005, many people criticized 15- 15- 15 fertilizer, but after more than ten years, these fertilizers are still welcomed by farmers in the market. Welcome to say that these fertilizers have certain scientific basis. Especially for our country's agricultural production, these fertilizers are more suitable as basic fertilizers. The same fertilizer is 15- 15- 15.

Bai also pointed out that in the process of inspecting the structural reform of fertilizer suppliers, I hope to hear the voices of fertilizer innovation from all sides, especially the direction of innovation. The structural reform of chemical fertilizer suppliers must first determine what problems must be solved in the supply side and industrial development. The chemical fertilizer industry in China not only ensures the food security in China, but also contributes to the protection of the ecological environment.
