The study sought to identify and quantify the effect of methods of tillage soil and solid waste management of the harvest on water erosion and initial development of the forest in a Inceptisoil. The test was installed in an experimental area of Aracruz Pulp and Paper S. A., located in the municipality of Arroio dos Ratos in the physiografic region called the Depression Center. The experimental design used was random block with three repetitions. The treatments tested were interrupted ripping with residue (CRS), continuous ripping with residue (SCR), continuous without residue (SSR) all in the direction of the slope and mechanical digging (CME). The loss of soil from SSR was ten times larger than the other treatment of ripping and one hundred times greater if compared to mechanic digging. The water disposed superficial treatment with residue was 1.6%. In ripping without residue, disposal was 2.9% of the total precipitate. The more intensive preparation increases soil erosion but favors the initial growth of eucalyptus. The maintenance of residue provides an appropriate development of eucalyptus plants and reduces the loss of water, and soil.
