Abstract
In integrated crop - livestock systems (ICLS), g rain crop and pasture development may affect the soil organic carbon stocks and chemical soil fertility and help to renew degraded pastures, increasing land use efficiency and endeavor income. Our objectives were to evaluate changes in the soil chemical pr operties, carbon stock in soil and carbon stratification rates of a typical Acrudox soil, with or without ICLS, liming and fertilization. The systems studied integrated with maize were: (i) Urochloa brizantha cv. Marandu (ICLS - Ub - Mar), (ii) U. brizantha cv . Piata (ICLS - Ub - Pia) and (iii) U. ruziziensis ICLS - Ur) and (iv) U. brizantha cv. Marand u (untreated control - UC) single without maize intercropped. Experiment was performed at the Institute of Animal Science in the municipality of Nova Odessa, Sao Paulo St ate (Brazil) using a randomized blocks experimental design. ICLS
