Nitrogen (N) availability is thought to frequently limit terrestrial ecosystem processes, and
explicit consideration of N biogeochemistry, including biological N2 fixation, is central to …

Microorganisms play a fundamental role in biogeochemical cycling and are highly sensitive
to environmental factors, including the physiochemical properties of the soils and the …

Ammonia oxidation is a central step in the global nitrogen cycle that involves several
different-conditions and metabolic bioprocesses, including aerobic versus anaerobic …

Nitrogen (N) cycling in forest ecosystems has been extensively studied over the past
decade. However, even with this concentrated research effort, we still do not have a …

Denitrification beds are containers filled with wood by-products that serve as a carbon and
energy source to denitrifiers, which reduce nitrate (NO3−) from point source discharges into …

Nitrogen (N) is an essential element associated with crop yield and its availability is largely
controlled by microbially-mediated processes. The abundance of microbial functional genes …

Biological nitrogen fixation, conducted by soil diazotrophs, is the primary nitrogen source for
natural grasslands. However, the diazotrophs in grassland soils are still far from fully …

Grazing exclusion alters grassland soil aggregation, microbiome composition, and
biogeochemical processes. However, the long‐term effects of grazing exclusion on the …

Purpose Biological nitrogen fixation (BNF) plays an important role in nitrogen cycling by
transferring atmospheric dinitrogen to the soil. BNF is performed by symbiotic and …

At the end of the 20th century, China launched the 'Grain-for-Green'Project (GGP) that
recommended the abandonment of low-yielding sloping farmland (> 15°) prone to soil …
