Seasonal responses of carbon, nitrogen, and phosphorus cycling to woodland reduction and different organic matter additions in the semiarid Great Basin
… microbially-mediated processes of decomposition and mineralization of organic matter carry ecosystem-level consequences because soil microorganisms can immobilize nutrients or render them available for plant uptake. The stochastic nature of resource availability in drylands may cause these …

A preliminary study of the impacts of alien Acacia infestation (A saligna) on the relative rates of nitrogen and phosphorus cycling in Lowland Fynbos, southwestern Cape, South Africa
This study was carried out on Sand Plain Lowland fynbos at Pella from April to September 1988. Environmental factors, nitrogen and phosphorus pool sizes and mineralization processes were investigated in the surface soils (1-10cm) of 7-8 year old fynbos vegetation and an adjacent Acacia saligna …

Effects of different canopy tree species on belowground biogeochemistry in a wet lowland tropical forest
… unclear. Interspecies differences in both the demand for nutrients and in foliar nutrient concentrations could drive differences in litter chemistry that affect both pools and fluxes of belowground resources. Yet, our understanding of the effects of aboveground biogeochemical heterogeneity on …
