Recent years, many parts of China have the phenomenon of excess partial nitrogen in some areas, especially in economically developed regions and phenomena on crops of high economic value, the excess application of nitrogen fertilizer is also more common, causing serious loss of nitrogen and Phosphorus accumulation in soil in some areas. In addition, the large amount of organic waste is not able to return to the farmland effectively, posing a threat to the environment. However, fewer people and more of our national conditions, the fertilizer must meet the continued growth of crop production, farmers continued to increase, continued to improve agricultural productivity, rural environment continued to improve the goal of sustainable development.

To achieve this goal, it is necessary to improve fertilization technology, reduce nitrogen loss, increase the recovery rate of nitrogen fertilizer in the current season, and improve the economic benefits of fertilizer application such as nitrogen , phosphorus and potassium. To the characteristics of China's use of high-intensity farmland has on basic and applied basic research breakthroughs, innovation in technology research, and lay a solid foundation in soil fertility and fertilizer-effective monitoring and management. To this end, the following suggestions are proposed: strengthening the basic rules of soil nutrient cycling and the basic application of fertilizers . Different nutrients have their own unique transformation cycles in different soil environments . Different nutrients are in different forms, organic or inorganic. After being applied to farmland, there are laws for their release, transformation, migration, and absorption, utilization, and reuse by crops. On the farm and regional scale, the absorption of nutrient supply and crop cycle has a specific use of the law of space and time, these rules will greatly affect the rate of loss of efficiency and fertilizer. Therefore, the specific situation of each region, to carry out related basis and applied basic research, it is the fundamental demand for sustainable and efficient use of soil fertilization.

Strengthen basic work such as soil fertility and fertilizer benefit monitoring

Soil fertility is the basis for sustainable development of agriculture, fertilizer efficiency is the basis for efficient use of fertilizer resources, to protect the long-term sustainable use of agricultural fertilizers and efficient use of resources, the need to strengthen national soil fertility monitor on the main agricultural areas and major soil base building and the establishment of national fertilizer efficiency test network in real time to master the national and soil nutrient status and productivity of the region, real-time control and the country's major agricultural areas of major crops and trace elements NPK fertilizer response and increase fertilizer production Benefits, at the same time, with the help of information, databases, network technology, etc., gradually establish national and local levels of soil fertility and fertilizer benefit monitoring and management network, and form a national soil and fertilizer information exchange and management system.

　 Achieve balanced fertilization and cultivate balanced, fertile and healthy farmland
