* Geological domains obtained from DNPM/CPRM (1978), where: 
Qa: Quaternary sedimentary deposits, mainly aluvial. 
TQi: Undifferentiated covers, involving Latosols with paleopavings. 
Kb: Bauru Formation — sandstones with medium granules, clayev, reddish pink and whitish to reddish, quartzons, locally with 
coarse sandstones, with crossed and plain stratification having small to medium portment. 
KJsg: Sao Bento Group - Serra Geral Formation — basaltic flows with sandier lenses and layers (Botucatu sandstone type). 
KJb: Sào Bento Group - Botucatu Formation — sandstones with fine to medium granules, well selected, whitish to reddish, quartzons; 
locally with coarse sandstones beds, with tangential, crossed stratification, having large portment at the base. 
Pci: Tubardo Super Group — Undifferentiated Itararé Group — coarse to fine sandstones, yellowish to reddish color, with 
development linked to red-brick color diamictites, grading to sandier and silty pellitic material; present crossed and plain 
stratification having small to medium portment.

the model established by Andrade ef al (1998) that, after field gently  undulated, | undulated and strongly undulated) 
evaluation, proved valid for the region of Machado. During the predominating in the undulated class, where it represents 
fieldwork, soils with humic/umbric epipedons were observed, 9,19%. This distribution reflects the geomorphology of the

between slope classes and altitude classes was used to separate Machado divided the region into two large environments: 
these soil-mapping units and representative soil profiles were 
described and sampled to confirm their occurfence. e  Geomorpho-pedological environment N-NE-E: with 
predominance of Latosols, in predominantly flat to 
undulated landscapes, occurring in the north, 
northeast and eastern regions in relation to the urban

Tables 6 and 7 show the results from the cross tabulations 
between Land Use Classes x Soil Classes and Land Use Classes 
X Slope Classes, respectively, for the pilot area of Machado.
