　　Soil organic carbon(SOC)is a key soil quality indicator for agricultural systems sustainability.We evaluated 20 yrs.soil use intensity effects on SOC(0-5 cm and 5-15 cm depth)in a 72 ha no-till crop-pasture rotation experiment under direct grazing(33°:15'36"S,54°:29'26"W,60-m elevation)in Uruguay(Abruptic Argiaquolls and Oxiaquic Vertic Argiudolls).
