The role of , in curbing ammonia volatilization from flooded rice systems, is to be preserved, intensification strategies should rely on integrated nutrient management, making full use of biological nitrogen fixation. The . complex is amongst the most effective systems of fixing nitrogen. In this paper we present evidence from greenhouse studies on the potential of . to c

Use of 15N for fertilizer N recovery and N mineralization studies in semi-arid Kenya,il N supply by gross mineralization were calculated. On average, modelled gross soil N mineralized could supply much (> 69%) of the N removed from the plots. It is suggested that the lack of response to fertilizer N may be explained by the coincidence of a high rate of N mineralization, and increased crop demand, caused by the onset of rain.
