RESUMO

The environmental recuperation of areas explored by sand mining in the Vale do Paraíba region, in the State of São Paulo, is a popular aspiration, a constitutional obligation and constitutes a differentiating factor in the visions of modern enterprise. This work studies the utilization of peat as a soil conditioner in the final stage of the recuperation process for these areas: the revival of indigenous vegetation. This idea arose from the author s experience in technological and mineral research into peat, coupled with the observation and monitoring of these environmentally sensitive areas, whose soils were, from an agricultural stance, generally unproductive. The utilization of peat, in these cases, represented the difference between success and the necessity for a replantation process. This study presents a review of the agronomic properties of peat as well as the application of organic matter in the revegetation of damaged land. It is a comparative study between laboratory assay results from soil samples in their original state, and those where the soil has variable peat contents, seeking to ascertain which, if any, results in better general conditions for that particular soil. Both physical and chemical properties were analyzed, with an emphasis on cation exchange capacity, buffering, bulk density, hydraulic conductivity and porosity. There is a possibility that the results of this project can extended beyond the Mineral Industry to other sectors, where there are needs for soil recuperation, leading to cost savings for irrigation, fertilizers and agrotoxic compounds in food production areas.
