To maintain soil fertility, the application of organic matters and crop rotation have been practiced. Farmers can use convenient chemical nitrogen fertilizers to obtain high crop yields. However, the inappropriate use of nitrogen fertilizers causes environmental problems such as nitrate leaching, contamination in groundwater, and the emission of N2O gas. This book is divided into the following four sections: "Ecology and Environmental Aspects of Nitrogen in Agriculture", "Nitrogen Fertilizers and Nitrogen Management in Agriculture", "N Utilization and Metabolism in Crops", "Plant-Microbe Interactions". 517 $aNitrogen in Agriculture 606 $aNitrogen in agriculture 615 0$aNitrogen in agriculture. 676 $a631.84 700 $aOhyama$b Takuji$01365077 701 $aInubushi$b Kazuyuki$01365078 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910688592003321 996 $aNitrogen in Agriculture$93386729 997 $aUNINA
