Effect of cultivation on the nitrogen fertility of selected agro-ecosystems in South Africa,agro-ecosystems and the rate of loss was rapid during the first few years of cultivation. Thereafter, the rate decreased until an equilibrium was approached. In agro-ecosystems from the warmer, drier regions, an equilibrium was approached much sooner than in agro-ecosystems from the cooler, wetter r

Assessment of biological nitrogen fixation,e auto-inhibition of acetylene conversion to ethylene. The ARA technique is therefore not a method of choice for measuring BNF..The xylem-solute technique can be used to measure BNF for those species that produce significant quantities of ureide as product of BNF. Although simple and relatively inex

Rational nitrogen fertilization in intensive cropping systems,nt approaches. Soil incubations in the field provide a quantitative approach while soil nitrate tests during the growing season provide a qualitative approach to estimating N mineralization. The plant is the ultimate integrator of N mineralization. Plant N uptake by an unfertilized crop can provide

,Nitrogen assimilation by legumes — processes and ecological limitations,fixation by legumes..There is no convincing evidence that N. fixation by legumes is generally limited by energy supply to nodules. On the other hand, N. fixation is often restricted by environmental constraints. Environmental stresses may limit N. fixation of legumes at four different levels: . mult

Brown leaf spot disease and fertilizer interaction in irrigated rice growing on different soil typeof brown leaf spot on irrigated rice at Caroni is influenced by sub-optimal levels paticularly of P. Careful monitoring and managememt of P nutrition is seen as an important part in the overall strategy for controlling the disease.
