Soil classification is a valuable tool in the ordination of its use and management, reducing the potential of this resource be used above or below its support capacity, and, thus, is a mechanism for its conservation. Contrasting with the conservation of soil, gullies are the most serious form of erosion and are generated by the concentration of runoff in rills, which expand and form large incisions. This form of soil degradation has several examples in the literature, which characterizes it as being an extensive problem. Thus, the development of technologies for the recovery and / or stabilization of gullies at low cost by using alternative materials so this practice has greater economic viability, is required. In this paper, the method used in the recovery of this erosion was the use of scrap tires as materials for its fill as well as use of mechanical, vegetative and soil management practices for its conservation. It was proceeded the evaluation of this recovery technique, and both the taxonomic classification of this soil, by Brazilian System of Soil Classification (Sistema Brasileiro de Classificação dos Solos, Embrapa, 2006) as the technique classification, by the Evaluation System of Agricultural Soil Suitability (Sistema de Avaliação da Aptidão Agrícola dos Solos, Ramalho Filho & Beek, 1995) of a soil of a lot of Agrarian Reform Settlement, in the city of Baliza – GO. This soil is degraded, and goes through an intensive process of linear erosion, both by rill as for gully erosion. The classification of this soil proved to be a valuable tool to determine its limitations and better use and management. With this tool was possible to determine the severe limitations that this soil have for agricultural use, as well as infer about the low level of technology under which this soil is handled that is taking it to its degradation. The technique adopted to halt this gully was efficient to contain the progress of erosion. Despite the adoption of an alternative technique for recovery the soil, a large amount of money was spent for the stabilization of soil erosion, which showed the severity of this problem. Despite the stabilization of this erosion have had the involvement of local residents, after the end of this intervention, they did not continue to adopt the practices of soil conservation that were recommended. Thus, the lack of maintenance, by the neighboring farmers to gully erosion, in the stabilized area, may propitiate the emergence of new erosion in that area.
