Soil fungi and bacteria are the key players in the transformation and processing of carbon
and nutrients in terrestrial ecosystems, yet controls on their abundance and activity are not …

Erosion by wind is one of the principal processes associated with land degradation in
drylands and is a significant concern to land managers and policymakers globally. In the …

Nitrogen (N) and phosphorus (P) limitation constrains the magnitude of terrestrial carbon
uptake in response to elevated carbon dioxide and climate change. However, global maps …

Soil organic carbon (SOC) is the largest terrestrial carbon (C) pool and is vulnerable to
climate and land-use changes. Promoting the stabilization of SOC will reduce climate …

Carbon (C) and nitrogen (N) are the primary elements involved in the growth and
development of plants. The C: N ratio is an indicator of nitrogen use efficiency (NUE) and an …

Potassium (K+) is the most abundant inorganic cation in plant cells, playing a critical role in
various plant functions. However, the impacts of K on natural terrestrial ecosystems have …

Because the capability of terrestrial ecosystems to fix carbon is constrained by nutrient
availability, understanding how nutrients limit plant growth is a key contemporary question …

Amazonia contains the most extensive tropical forests on Earth, but Amazon carbon sinks of
atmospheric CO2 are declining, as deforestation and climate-change-associated droughts …

A global assessment of precipitation chemistry and deposition has been carried out under
the direction of the World Meteorological Organization (WMO) Global Atmosphere Watch …

Most of Earth's terrestrial surface is made up of slo** landscapes. The lateral distribution
of topsoil by erosion controls the availability, stock, and persistence of essential elements in …
