Inhibited vertical mobility of biochar-derived dissolved organic matter under low-intensity rainfall: role of mineral retention

Biochar
Biochar has great potential in the application areas of carbon sequestration and environmental remediation. A significant amount of dissolved organic matter (DOM) may be released from biochar, which is highly reactive and mobile.

Modeling Soil Organic Carbon Dynamics, Carbon Sequestration, and the Climate Benefit of Sequestration

, 2021
Mathematical models are essential for integrating different processes that control rates of soil C dynamics and for assessing C sequestration and related climate benefits. Many models have been proposed in the literature to predict C stocks and fluxes, with no overall consensus on the best model that can provide relevant insights at a large range of ...

Biochar-mediated degradation of p-nitrophenol as influenced by species of Fe(III)

Biochar
The presence of Fe(III) or oxygen can affect the biochar-mediated degradation of pollutants. However, the effects of changes in the form and species of Fe(III) on the degradation of pollutants have not been systematically investigated.

Carbon sequestration on Mars: REPLY [PDF]

Geology, 2016
Martian atmospheric pressure has important implications for the past and present habitability of the planet, including the timing and causes of environmental change. The ancient Martian surface is strewn with evidence for early water bound in minerals (e.g., Ehlmann and Edwards, 2014) and recorded in surface features such as large catastrophically
