Resumo
Soil provides important support for anthropogenic activities, and earthen trails,
which have always been present in the natural landscape, are routes of access to various
tourist attractions. In recent decades, trails have been widely used as a method of
access and visitation to geotouristic attractions. Because trails are restricted routes,
transit along these paths also transforms the route into a pathway for the spread of
various negative environmental impacts, including compaction and soil erosion of the
trailbed. Soil compaction is caused by changes in the soil structure that are partly induced
by the use of agricultural or geotechnical machinery and traffic, and the damage
is also manifested in a remarkable decrease in porosity, which has clear implications
for the infiltration and percolation of water and air associated with the functional porosity
of soil. Soil micromorphological characteristics contribute to the analysis of soil
porous systems, and the macroporous characteristics visible at this scale include the
size, shape and connectivity among voids, which can be studied using different methods
of identification, measurement and interpretation. Such methods are applied to
understand the pore genesis and, more importantly, the physical behavior of soil-water
order management. This work presents the results of analyses of the macromorphological
and micromorphological characteristics, porosity, texture and penetrometry
resistance of soil profiles on the Farofa Waterfall trail in the Serra do Cipó National
Park, and the aim is to provide recommendations for compaction studies along special
trails. The results showed that most of the trailbed is more compressed than at the
margins, which suggests the need for geoindicator studies of soil quality to monitor the
visitation of the trail and improve the conservation of natural resources.
