Nitrogen fertilizer is still the driving force for increasing crop production in China. However, after 30 years of continuous heavy application, it will have a negative impact on China's food security. Some greenhouses and land due to excessive fertilization, there have been "dead shed", "dead" phenomenon. At present, the utilization rate of high inorganic fertilization in farmland in China is only 25% to 30%, which is far below the level of more than 40% in developed countries.
The loss of vegetables and the depletion of land are not the only consequences of excessive nitrogen fertilizer application. A survey of agricultural experts showed that at more than 800 survey sites, 50% of the groundwater nitrite content was exceeded by excessive nitrogen, and nitrite was a carcinogen. It is predicted that in 2015, all provinces in central and southeastern provinces except Jiangxi and Shanxi provinces will become potential high-risk areas with excessive nitrite content in groundwater due to excessive nitrogen use.
Farmers, for your own sake, for your loved ones, and for your offspring, please use nitrogen fertilizer carefully! ! !
