The effects of forest management on soil carbon (C) and nitrogen (N) are important to
understand not only because these are often master variables determining soil fertility but …

Nitrification, a microbial process, is a key component and integral part of the nitrogen (N)
cycle. Soil N is in a constant state of flux, moving and changing chemical forms. During …

The ecological principles that define the competitive and complementary interactions among
trees, crops, and fauna in agroforestry systems have received considerable research …

The literature on soil C change with forest harvesting, cultivation, site preparation, burning,
fertilization, N fixation, and species change is reviewed. No general trend toward lower soil …

Abstract Surface water nitrate (NO− 3) pollution from agricultural production is well
established, although few studies have linked field N budgets, NO− 3 loss in tile drained …

More than 200 angiosperms, distributed in 25 genera, develop root nodule symbioses
(actinorhizas) with soil bacteria of the actinomycetous genus Frankia. Although most soils …

Nitrogen (N) availability influences carbon (C) storage in forest soils through effects on plant
growth, litter production, and soil C decomposition and stabilization. Soil C/N and net N …

To investigate the impact of human disturbance and subsequent recovery on soil nitrogen
processes, nitrogen availability during different seasons and at two soil depths in disturbed …

O ciclo biogeoquímico do nitrogênio apresenta um conjunto diverso de transformações que
envolve a ocorrência deste elemento no solo, no ar e na água e que são, na maioria das …

Belowground competitive and complementary interactions define productivity and
sustainability of mixed-species plantations to a large extent, but have received relatively little …
