QUANTIFICAÇÃO DAS EMISSÕES DE CO2 PELO SOLO EM ÁREAS SOB DIFERENTES ESTÁDIOS DE RESTAURAÇÃO NO DOMÍNIO DA MATA ATLÂNTICA

In order to quantify emission rates of CO2 through the soil from the Atlantic forest under different regeneration stages, two areas located in Rio Claro(SP) were studied. In the first area the forest is regenerated (Plot 23) and the average CO2 emission is 1.91 mmol m-2s-1, while in the recently planted area (Plot 15), the average emission is 1.38 mmol m-2s-1. The CO2 emissions are fairly correlated to soil moisture (r=0.53, P=
