Advances in Nitrogen Management for Water Quality

Scientific literature provides overwhelming evidence of the importance of managing nitrogen (N) to protect water quality as well as the environment in general. The goal of this chapter is to address many of the questions concerning this subject. Enhanced N management is increasingly necessary to decrease the impacts that excessive amounts of N in its reactive forms (i.e., Nr) can have on ecosystems. Dinitrogen gas (N2) is the most abundant element in the Earth’s atmosphere and available for metabolism in biological systems, yet once the triple bond of the N2 molecule is broken the single N atoms become reactive (Nr) and bonds with elements, such as oxygen (O), carbon (C), and hydrogen (H), to form some of the most mobile ionic substances found in the soilplant- atmosphere system.
