The Corumbatai Basin located in the Northeast of São Paulo State, between parallels 22º05′ and 22º30′ S and meridians 47º30′ and 47º50′ WG, has its lands assessed for soil erodibility and agricultural aptitude, using the specialist software SAMPA 2.0 developed by São Paulo State University (UNESP) researchers for automatíc land evaluation using soil and topographic information. The results obtained, maps and charts, led to the following conclusions: a) Lands with fair aptitude for long cycle cultures (fruits, sugarcane, etc.), pasture and forestry, and restricted/unfit for short cycle cultures (grain, vegetables, etc.) are pre-dominant; b) Main land limitations for short cycle cultures are a consequence of the predominance of sand texture soils, with low fertility, medium to high aluminum toxicity, low water store capability and moderate to high erosion susceptibility; c) About 53% of the area present moderate to high soil erosion susceptibility and 35.5% present very high to excessive susceptibility.
Keywords: Land evaluation, soil erosion, rural planning, GIS, Corumbatai basin.
