ABSTRACT
This study was done to evaluate the spatial variability of carbon stock in a red-yellow Latosol humic soil in two plantationsof arabic coffee (Coffea arabica L) variety ‘catuaí’ or ‘catucaí’ located on hillslope. The carbon stock was determined byth use of soil density and total organic carbon and the data were analyzed by classical and geo-statistics. The carbon stockwas lower under ‘catucaí’ plantation compared to the area under ‘catuaí’ plantation. In both areas highest stocks werefound on sites of higher soil density.
