Abstract

The objective of this study was to classify the lands of a micro-watershed located in the Atlantic forest biome, in a region of rough relief, in the use capacity system using geotechnology resources and indicate uses for the lands according to their suitability. The theoretical basis of the Manual for Utilitarian Survey and Classification of Land in the Use Capacity System with adaptations for areas of rough relief was adopted. The study was carried out from the survey of topographic information to construct the altimetric map of the watershed, followed by the survey of the physical environment, especially water erosion, description of soil profiles and collection of samples. The parameters effective depth, texture, permeability, slope, erosion, fertility, and land use were evaluated. Based on the pedological data and on the use of applied geotechnology, the soil map was created, and the lands of the watershed were classified and mapped in the use capacity system. After interpretation of the survey products, it was verified that in rough relief, slope is the predominant factor to determine the classes of land use, as it outweighs the other parameters evaluated. Land classification land with the use capacity system promotes optimization in the use of areas with agricultural areas and preservation of those destined for conservation.

Highlights

The concern with soil conservation in agricultural areas dates back to the nineteenth century, especially in the UnitedStates of America
This concern with and dissemination of the subject led to the emergence at the time of a classification of lands focused on their agricultural use capacity, prioritizing soil conservation in the Pennsylvania Soil Survey, including the mapping of land use (Gardner, 1998; Lepsch et al, 2015)
In Brazil, land use and occupation became important after agronomists, extensionists and researchers became aware of the studies conducted by North American researchers and producers in the early twentieth century (Lepsch et al, 2015)

Summary

Introduction

The concern with soil conservation in agricultural areas dates back to the nineteenth century, especially in the UnitedStates of America. At that time American pedologists already warned of the risks of water erosion and its consequences for agricultural production and preservation of natural resources (Bertoni and Lombardi Neto, 2012; Lepsch et al, 2015). This concern with and dissemination of the subject led to the emergence at the time of a classification of lands focused on their agricultural use capacity, prioritizing soil conservation in the Pennsylvania Soil Survey, including the mapping of land use (Gardner, 1998; Lepsch et al, 2015).
