  • >pstrong< >/strong/p<>psub<2>/sub<, organic matter also increases the soil CEC, thus buffering changes in soil pH. Carbon sequestration and nutrients availability due to enhanced weathering are quantified, in this study, as a function of MAP (Mean Annual Precipitation). Average CO>sub<2 >/sub-1 y-1 for MAP higher than 2000 mm, condition that is always reached in the tropics. This CO>sub<2 >/subsub<3>/sub<-) and carbonate (CO>sub<3>/sub<2-) ions and will be leached away from the domain, eventually reaching the ocean. In presence of tropical climate olivine application also leads to an increase of soil pH and nutrients availability, especially calcium and magnesium, which in turn can enhance plant productivity. This study paves the way for a potential integration of enhanced weathering in agroecosystem management practices, especially in humid tropical regions since these are characterized by high MAP and temperature.>/p<
