Chemical Fertilizer and Ecological Health
BAI Youlu;Institute of Agriculture Resources and Regional Planning, Chinese Academy of Agricultural Sciences/Key Laboratory of Plant Nutrition and Fertilizer, Ministry of Agriculture and Rural Affairs;
Since the advent of chemical fertilizer, world food security has been greatly guaranteed. Besause chemical fertilizer can greatly increase the yield of grain, which saves a lot of farmland, a lot of land that is not suitable for agricultural cultivation is used for ecological construction. Therefore, to a certain extent, chemical fertilizer ensures the healthy development of the ecological environment. But the heavy use of chemical fertilizers may also bring certain negative effects, such as eutrophication of water bodies and other ecological health problems. However, the measure to solve these problems is to rationally apply chemical fertilizer, rather than refuse to use chemical fertilizer. Modern agriculture cannot do without chemical fertilizer, and ecological health cannot do without chemical fertilizer, too.
