Forms and nature of organic N in soil. Seasonal fluctuations of native available N and soil management implications. Effect of cultivation on the nitrogen fertility of selected agro-ecosystems in south Africa. Assessment of biological nitrogen fixation. High productivity analysis of 15N and 13C in soil/plant research. Adapting the potencially mineralizable N concept for the prediction of fertilizer N requirements. Field application of the 15N isotope dilution technique for the reliable quantification of plant-associated biological nitrogen fixation. Rational nitrogen fertilization in intensive cropping systems. Nitrogen assimilation by legumes-processes and ecological limitations.
