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.

Incipient ferralization and weathering indices along a soil chronosequence in Taiwan [PDF]

, 2016
The low hilly topography of Green Island, a volcanic island off southeastern Taiwan, includes an altitudinal sequence of sub-horizontal benches. We examined eight profiles along this sequence, ranging from pale brown loamy coral sand on the lowest bench ...

Vegetation of the gnamma of the Sierra de Guadarrama and La Serena (Spain)

Anales del Jardín Botánico de Madrid, 2009
Weathering pits are wetlands of geomorphologic and biological interest, but this common fact is obscured by the different names used by biologists, such as the ambiguous name of rock pool.
