A conceptual assessment of the importance of denitrification as a source of soil nitrogen loss in tagement on C and N turnover. The data analysis also suggests that, just as in temperate regions, denitrification may not be a significant route of N loss from most tropical agricultural systems. However, field studies are necessary to determine if this is actually the case.

Downward movement of nitrate and ammonium nitrogen in a flatland ultisol,Mulch application decreased NH.-N and NO.-N soil levels. Ridging the soil increased downward movement of NH.-N and NO.-N. Under bare-fallowed conditions, downward movement of NH.-N was noted in the 30 to 45 cm soil layer at seven days after fertilization, while under cropped conditions its movement

M. T. F. Wong,S. Nortcliffe incoherent, leading thus to incorrect explanations. Then, we show that explanations are provided by non-monotonic functions. Indeed, an explanation may no longer be valid if new instances are received. Finally, we provide a novel function that is based on argumentation and that returns plausible e
