Minerals and organic matter (OM) may form intricate associations via myriad interactions. In
soils, the associations of OM with mineral surfaces are mainly investigated because of their …

Rock weathering is a key process in global elemental cycling. Life participates in this
process with tangible consequences observed from the mineral interface to the planetary …

The base of Earth's critical zone (CZ) is commonly shielded from study by many meters of
overlying rock and regolith. Though deep CZ processes may seem far removed from the …

Atmospheric change encompassing a rising carbon dioxide (CO 2) concentration is one
component of Global Change that affects various ecosystem processes and functions. The …

Hydrology is an integrative discipline linking the broad array of water‐related research with
physical, ecological, and social sciences. The increasing breadth of hydrological research …

The Paleozoic emergence of terrestrial plants has been linked to a stepwise increase in
Earth's O 2 levels and a cooling of Earth's climate by drawdown of atmospheric CO 2 …

Carbon mineralization sequesters CO2 by reaction of alkaline earth metal bearing silicate
and hydroxide minerals with CO2 to form stable carbonate minerals. Seifritz (1990) …

Earth's land surface teems with life. Although the distribution of ecosystems is largely
explained by temperature and precipitation, vegetation can vary markedly with little variation …

Because there remains a lack of knowledge about the spatially explicit distribution of
chemical weathering rates at the global scale, a model that considers prominent first-order …

Plant nutrients can be recycled through microbial decomposition of organic matter but
replacement of base cations and phosphorus, lost through harvesting of biomass/biofuels or …
