Abstract
Sedimentary soils in southwestern Amazon are associated with the occurrence of high activity clays, with wide variability in small territorial extension. Planning activities for of land use capacity at the scale needed at the farm cannot be done properly by the regular Brazilian system. Thus, the purpose of this study was to compare an alternative system for the evaluation of land suitability, with the original methodology, using published data of nineteen soil profiles from pedological survey of the district Thaumaturgo, Acre, Brazil. The results indicated that the alternative system was sensitive to identify agricultural limiting factors, except for a Gley and Fluvent soils. For Fluvents and other soils (Ultisols, Inceptisols, Chernosol, Luvisols), alternative system indicated land use most suitable for the region. In most situations, compared to the original method, soil uses systems more conservationists was indicate for fragile soils (soils least-developed) and more intense soil use systems for fragile soils. Keywords : land use; planning territorial; environmental evaluation.

Essa metodologia foi desenvolvida para a interpretação sistemática de levantamento de solos, e apropriada para avaliar a aptidão agrícola de grandes extensões de terras, devendo, conforme seus próprios idealizadores, sofrer reajustamentos para sua aplicação individualmente pequenas glebas de produtores (RAMALHO FILHO; BEEK, 1995)
