It is understood that from July 1, 2012, China's first industry standard for new nitrogen fertilizer - Urea ammonium nitrogen fertilizer industry standards HG/T4214-2011 will soon be implemented. The implementation of this standard will put an end to fake urea ammonium products to a certain extent, effectively purify the urea nitrogen fertilizer market, and at the same time further specify the direction of development of the industry, promote orderly competition in the industry, and allow more farmers to recognize and accept new nitrogen fertilizers. At present, China's nitrogen fertilizer value-added research has physical, biological, and chemical methods. The physical laws generally adopt controlled release rates to extend the fertilizer efficiency of nitrogen fertilizers. Sustained controlled release is mainly based on the envelope method and stabilization method. Among them, there are organic coatings such as resin, cellulose, and paraffin, as well as inorganic coatings such as sulfur, calcium magnesium phosphate, and the like. The most important feature of slow- and controlled-release fertilizers is the synchronization of nutrient release and crop absorption, simplification of fertilization techniques, and the need for one-time fertilization to meet the entire growth period of crops, with low fertilizer loss, high utilization rate, and environmental friendliness. The focus of fertilizer research in the future should be on how to increase fertilizer efficiency and utilization rather than continue to substantially increase fertilization. Therefore, by renewing concepts and breaking the tradition, China’s fertilizer industry will strive to implement quality replacement quantitative development strategies in the future. The supply of chemical fertilizers will strive to be controlled within 50 million tons, and by ensuring efficiency without increasing or slightly increasing the amount of chemical fertilizers, we will ensure our country’s efficiency.
