Advances in methodology for research on nitrogen transformations in soils

Research output: Chapter in Book/Report/Conference proceedingChapter


This chapter reviews the methodology employed in soil nitrogen (N) research, following the review by J. M. Bremner and R. D. Hauck. Advances in analytical instrumentation and techniques have played a key role in the proliferation of research since 1980 concerning the nature and transformations of soil N, particularly as regards agricultural productivity and environmental quality. The application of enzymatic assay techniques in soil N research has focused primarily on the role of nitrogenase in biological N2 fixation and the hydrolysis of urea by soil urease. Environmental applications of molecular genetics have focused largely on xenobiotic degradation, but N-cycle processes also have been a subject of investigation, particularly N2 fixation, nitrification, and denitrification. Limmer et al. have utilized a different form of isotope dilution to detect emission of N2 generated during denitrification under field conditions.
