  abstract = {{I}n 1991 in {M}artinique ({F}.{W}.{I}.), a #{D}igitaria decumbens$ pasture was established on a vertisol that had supported a market-gardening culture for more than 10 years. {O}rganic matter stock restoration was investigated by measuring carbon contents ({C} contents) and carbon/nitrogen ({C}/{N}) ratios each year from 1992 to 1997. {R}elations between and soil properties (particle-size distribution, soil depth) and {C} contents were studied. {F}urthermore, geostatistical analyses of {C} contents were realised in order to characterise the {C} storgae in soil at plot scale. {T}he increase of {C} contents from 1992 ({Y}0) to 1997 ({Y}5) was 5 g {C}/(kg soil) in the topsoil (0-10 cm) and 2.5 g {C}/kg soil, or 7.5 {M}g {C}/ha, in the 0-30-cm layer. {T}he intensity of organic {C} storage had a spatial pattern, although the {C}/{N} ratio remained homogeneous across the plot. {H}owever, there was no correlation between the {C} increase and the particle-size distribution or the depth of the soil. {I}n the topsoil, the local variability of the {C} contents increased with time until 1995 and then there was a gradually spreading of this local variability. {P}lant-cover distribution and physical structure of vertisol could explain the evolution of spatial structure of the soil {C} content.
