Capacity of soil use in the watershed of the Corriente del Lobo, Itatinga, São Paulo, Brazil
The objective of this research was to define the use capacity classes of 2403.25 ha in the basin of La Corriente del Lobo - Itatinga (SP), (22°03'56" to 22°59'12" of latitude S and 48°38'47" to 48°41'25" of longitude W Gr.). The soil use capacity was obtained by using the SIG IDRISI 32 crossing the documents of steepness and soils, and the document of judgment of soil use capacity classes and of the utility survey of the physical milieu. The areas with use capacity classes and subclasses presented the following values: IIIa - 68.60 ha (2.85%), IIIe,s - 1919.15 ha (79.86%); IIIe - 210.60 ha (8.76%); IVe - 3.38ha (0.14%); IVe,s - 157.42 ha (6.55%) and VIe,s - 44.10 ha (1.84%). The lands of the basin were distributed in three classes (III, IV and VI) and six subclasses, but the biggest extension (79.9%) belonged to the subclass IIIe,s. The modules of the IDRISI allowed to discriminate, mapping and to quickly quantify the soil use capacity of the areas of classes and subclasses in the basin.
