Generation of soil maps permeability. Case study in two cantons of Loja province, Ecuador

The generation of permeability maps is based on the analysis and interpretation geology, environmental morphology, land use, slope, which enables selection sampling areas with similar characteristics. method represents integration physical characteristics study area then determines infiltration capacity differences in most representative geopedologic units. In determining basic data, minidisc infiltrometers were used to perform seventy-two tests different types soils varying organic matter content, texture, soil structure, vegetation cover, showed spatial variability that exists two cantons Loja province, Ecuador. addition, it was observed rate depended mainly content consistent information collected worldwide. this study, generated pedotransfer function (FTP) coefficient determination R2 0.78, indicates a satisfactory estimate variables analyzed; methodology for assessing suitable conditions investigation. For reason, described here should be tested other country greater number field trials more variable contents textural classes.
