  abstract = {{T}he natural abundance of 13{C} was used to estimate the turnover of the soil organic matter in vertisol re-grassed with #{D}igitaria decumbens$ ({C}4 plant) following intensive market gardening ({C}3 plants). {I}n addition, the experimental design allowed us to determine the respective roles of roots and earthworms (#{P}olypheretima elongata$) in soil {C} stock restoration in #{D}. decumbens$ pasture. {T}he {C} stock increased from 31 to 37 {M}g {C}/ha in 5 years and the delta13{C} increased from -18.1% in market gardening soil to -15.5% in the 5-year-old pasture soil in the upper 20 cm. {B}elow the 20 cm soil layer, the {C} stock and the delta13{C} did not change significantly in 5 years. {T}he net gain of 6 {M}g {C}/ha was the balance of a loss of 5 {M}g {C}/ha derived from market gardening and a gain of 11 {M}g {C}/ha derived #{D}. decumbens$. {E}ffects of earthworms on the {C} dynamics were not dicernible.
