Some farmers like to buy "3 15" compound fertilizers. Why are some manufacturers unwilling to produce them?

"3 15" refers to a compound fertilizer with a nitrogen, phosphorus and potassium content of 15% and a total content of 45%. At present, the "Thirty-Five" compound fertilizer is difficult to trace, replaced by several types of mixed fertilizers and special fertilizers.

Some people think that "3 15" as a general-purpose compound fertilizer has two main disadvantages: first, serious homogenization, transparent prices, meager profits, and lack of motivation for distributors. Second, the fertilizer itself does not meet the requirements. Basic requirements for crops and scientific fertilization. Is this really the case? On March 26, the launching ceremony of the “2017 Fertilizer Supply-Side Structural Reform Survey” was held in Beijing. Bai Youlu, chairman of the China Nutrition and Plant Fertilizer Society, said that the fertilizer industry must first distinguish between the supply side and the supply side. From an industry-wide perspective, fertilizer homogenization is not an issue on the supply side. This is a competition issue in the fertilizer market.

Bai said that the problem of fertilizer supply is what kind of fertilizer China needs for agricultural production. Our fertilizer industry cannot produce it, or the fertilizer industry cannot meet the types of fertilizers needed for agricultural production. In China, it must be imported. Secondary issues Currently, in addition to potassium fertilizer, China's fertilizer industry also has the problem of overcapacity. The nitrogen fertilizer industry and the phosphate fertilizer industry have suffered total losses, but why China still imports a lot of fertilizers, and agriculture also prefers imported fertilizers, is worth considering.

Bai said that reforms in China's fertilizer supply require innovative fertilizers. Fertilizer innovation must start from the following aspects: 1. Centralization of innovation: Improving the concentration of nutrients in fertilizers has been the trend of international fertilizer development in recent decades. At present, everyone’s attention to fertilizers is mainly due to the unknown factors in fertilizers. Element. Fertilizer sub-ingredients for agricultural product quality, soil health and environmental safety. Uncertainty, in the case of low concentration, many sub-components are unclear, and the potential risks are also very scary. Therefore, increasing the concentration of fertilizer is one of the problems faced by the fertilizer industry. The second is the proportion of nutrients in the fertilizer. When soil testing and formulating began in 2005, many people criticized 15-15-15 fertilizers, but more than a decade later, these fertilizers are still popular with farmers on the market. Welcome indicates that these fertilizers have some scientific basis. Especially for agricultural production that is accustomed to planting in our country, these fertilizers are more suitable as basic fertilizers. The same fertilizer is 15-15-15.

Bai Youlu also proposed that in the process of investigating the structural reform of the fertilizer supply side, he hopes to hear voices from all sides regarding fertilizer innovation, especially the direction of innovation. Structural reform on the fertilizer supply side must first determine what problems must be solved on the supply side and what problems must be solved in industrial development. China's fertilizer industry not only provides guarantee for China's food safety, but also contributes to protecting the ecological environment.
