The effects of enhanced weathering and hydrology on carbon sequestration in soils

>psub<2>/sub<.>/p<>pstrong/strongem/em< technologies. These techniques involve removing CO>sub<2>/sub< from the atmosphere and storing the carbon within it in the oceans, terrestrial environments or geologic formations. The natural >strong/strongstrong/strong/p<>pstrong/strongsub<2>/sub< are much higher than those of other minerals. In this study, a model simulating the dynamics of the biogeochemistry of a soil treated with olivine under different climate scenarios is presented. The model is forced by a stochastic rainfall, simulated as a marked Poisson process, and puts together the ecohydrology and the biogeochemistry. Plants influence the whole system with their evapotranspiration, nutrients uptake (Na⁺, Ca²⁺ and Mg²⁺) and the addition of organic matter to the soil. Biogeochemistry involves all the aspects of the model related to the cycle of the dissolved ions (H⁺, Na⁺, Ca²⁺ and Mg²⁺), litter decomposition and the chemical reaction of olivine with CO>sub<2>/sub<.>/p<>p+, Ca²⁺ and Mg²⁺ concentrations, thus a certain amount of olivine can replace the addition of fertilizers. Therefore, this study proposes a natural solution for facing climate change problems and presents a model that could be used as a decision support system in land management.>/p<
