Resumo
Planning and environmental management are activities that aim to control and
suitable land use for maximum agricultural yield purposes, through a powerful operating
system, capable of sustaining human activities with a minimum of disturbances on
physical, ecological and social processes. To ensure the rational use of natural resources,
soil properties need to be taken in account, as well terrain steepness and water dynamics,
since they inform about cropping intensity and agronomic practices to be applied to soils,
in order to avoid exhaustion of productive capacity caused by erosion. This work aimed to
assess morphometric attributes related to soil distribution over the landscape and suggest
the land use potential, based on the roughness coefficient in the Alto Meia Ponte River
basin (Goiás, Brazil). Among the studied variables, morphometric attributes, associated to
roughness coefficient, proved to be a valuable tool for the definition of land use
potentialities in the diagnosis phase. They are low cost procedures, providing suitable
information about water dynamics and, or, hydrologic behavior, as well the ease of
gathering information. The use of roughness coefficient resulted in initial indication of the
watershed for livestock and reforestation. The intersection of roughness coefficient and soil
surveys data, associated with average land slopes, allowed to discriminate more areas
suited to farming activities and those more vulnerable to environmental degradation. The
refinement of information enabled the increase in areas liable to agricultural use, provided
that conservative and preventive measures of soil degradation are taken.
