Soils and sediments are major reservoirs of organic matter (OM), whose dynamic turnover
has a major impact on carbon cycling and global climate. OM in soils and sediments is …

Minerals are widely assumed to protect organic matter (OM) from degradation in the
environment, promoting the persistence of carbon in soil and sediments. In this Review, we …

Biogeochemical cycling of iron is crucial to many environmental processes, such as ocean
productivity, carbon storage, greenhouse gas emissions and the fate of nutrients, toxic …

Iron (Fe) is the fourth most abundant element in the earth's crust and plays important roles in
both biological and chemical processes. The redox reactivity of various Fe (II) forms has …

Mineral–microbe interactions play important roles in environmental change, biogeochemical
cycling of elements and formation of ore deposits. Minerals provide both beneficial (physical …

Hydroxyl radical (• OH) is an active species widely reported in studies across many scientific
fields, and hence, its reliable analysis is vitally important. Currently, alcohols are commonly …

Manganese (Mn) is a biologically important and redox-active metal that may exert a poorly
recognized control on carbon (C) cycling in terrestrial ecosystems. Manganese influences …

Understanding the controls on the amount and persistence of soil organic carbon (C) is
essential for predicting its sensitivity to global change. The response may depend on …

Dissolved organic matter (DOM) plays a vital role in biogeochemical processes and in
determining the responses of soil organic matter (SOM) to global change. Although the …

Although most organic matter (OM) in soil is mineralized by microorganisms, the
nonmicrobial processes, eg, Fenton reactions and photo-degradation, strongly contribute to …
