People engaged in chemical fertilizer production and application know that among the several principles of scientific fertilization, one is the law of diminishing returns: under the premise of relatively stable technical conditions (such as irrigation, variety, cultivation, etc.), as the amount of fertilizer is gradually increased, Crop production will also increase. When the amount of fertilization exceeds a certain limit, the amount of fertilization is increased, and on the contrary, crop production is reduced. This is a law of economics and is widely used in various fields such as industry, agriculture and animal husbandry production. In simple terms, it is farmers who invest a single yuan of chemical fertilizer, and the resulting benefits must be greater than one yuan to be profitable.

At present, all kinds of new fertilizer products in the market are more expensive than traditional fertilizer products. This virtually increases farmer's investment in agriculture. However, has anyone calculated whether the farmers can invest more money in these "new products"? They get more benefits.

For example, the use of chemical fertilizer products that have been stable for decades is now being adjusted by some companies, adding a few percent of the material and increasing the product price by a few hundred dollars. Is this material worth a few percent? A few hundred dollars? If the input-output ratio of new products purchased is unreasonable, it should not be promoted as a new product.

Fertilizer products have been very rich in development so far. But to increase crop yield, increase fertilizer use efficiency, and reduce surface pollution, it is only a way out to research new fertilizer products. The answer is no, the deep application of fertilizers promoted by the Ministry of Agriculture, layered fertilization, water and fertilizer integration are all good solutions. We must not only pay attention to the innovation of fertilizer products, but also pay more attention to the control of fertilization nodes and the rationalization of fertilization methods.

Deep application of fertilizers and stratified fertilization can not only increase crop yield but also have significant effects in increasing fertilizer utilization and increasing soil organic matter. Scientific fertilization still has a long way to go in China. Scientific fertilization first needs to instill the notion of scientific fertilization in farmers who are farming, rather than merely stressing innovations in fertilizer products.
