Soil warming and organic carbon content
WebSoil organic carbon –water partitioning coefficient K oc (adsorption coefficient) is a ratio of the mass of a chemical that is adsorbed in the soil per unit mass of organic carbon to its concentration in dilute aqueous solution, at equilibrium. The log K oc values are used for predicting the mobility of organic chemicals. Table 2.2 shows the log K oc values for the … WebNew study finds substantial loss of carbon, nitrogen from burned soils—and connections to warming climate PORTLAND, Ore. October 16, 2008. For decades, scientists and resource managers have known that wildfires affect forest soils, evidenced, in part, by the erosion that often occurs after a fire kills vegetation and disrupts soil structure. But, the lack of …
