In the natural environment, soil pH has an enormous influence on soil biogeochemical
processes. Soil pH is, therefore, described as the “master soil variable” that influences …

Northern ecosystems are experiencing some of the most dramatic impacts of global change
on Earth. Rising temperatures, hydrological intensification, changes in atmospheric acid …

Rice paddies account for~ 9% or the world's cropland area and are characterized by
environmental conditions promoting soil organic carbon storage, methane emissions and to …

Browning of surface waters because of increasing terrestrial dissolved organic carbon (OC)
concentrations is a concern for drinking water providers and can impact land carbon …

Dramatic environmental shifts are occuring throughout the Arctic from climate change, with
consequences for the cycling of mercury (Hg). This review summarizes the latest science on …

Inland waters transport large amounts of dissolved organic matter (DOM) from terrestrial
environments to the oceans, but DOM also reacts en route, with substantial water column …

Reduced atmospheric acid deposition has given rise to recovery from acidification–defined
as increasing pH, acid neutralization capacity (ANC), or alkalinity in surface waters. Strong …

Surface water browning, the result of increasing concentrations of dissolved organic matter
(DOM), has been widespread in northern ecosystems in recent decades. Here, we assess a …

Observations of increasing water color and organic carbon concentrations in lakes are
widespread across the Northern Hemisphere. The drivers of these trends are debated …

Significant increase in soil organic carbon (SOC) has been found in Chinese croplands.
Current literature largely attributes this to the increased organic C inputs from manure, crop …
