abstract soils constructed after mining often have low carbon (c) stocks and low quality of organic matter (OM). cover crops are decisive for the recovery process of these stocks, improving the quality of constructed soils. therefore, the goal of this study was to evaluate the effect of cover crops on total organic c (tOc) stocks, c distribution in physical fractions of OM and the c management index (cMi) of a soil constructed after coal mining. the experiment was initiated in 2003 with six treatments: Hemart…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
