Destabilization of carbon in tropical peatlands by enhanced weathering

Communications Earth & Environment, 2022
Enhanced weathering in tropical peatlands may be an ineffective carbon dioxide removal strategy due to pH-induced increases in soil carbon leaching which lead to increased re-emission of carbon, according to model calculations constrained by observations

Increase in cation exchange capacity by the action of maize rhizosphere on Mg or Fe biotite-rich rocks

Pesquisa Agropecuária Tropical, 2022
The weathering of some silicate minerals in crushed rocks may occur in a few days of cropping and generate different physicochemical properties, with potential benefits to tropical soils.

Role of the sediments of two tropical dam reservoirs in the flux of metallic elements to the water column [PDF]

, 2012
In tropical climates, the high rainfall and temperature, throughout the annual cycle, allow high leaching rates of metallic elements from the basin upstream, which accumulate in the reservoirs.
