Caracterização e comparação físico-hídrica de solos de encosta com floresta no município de Erechim- RS

Abstract

Brazil is one of the most important countries in agricultural production that over the years has been increasing its productivity with the use of modern technologies and the use of natural resources optimization. Currently, efforts have been made to improve production allied with the sustainable development of systems and the integrated use of land with farming, livestock, and forestry. Thus, the objective of the present study is to evaluate the physical-hydric aspects of hillside areas with the presence of forest. Therefore, the forest area was evaluated and characterized by analyzing the following parameters: particle density, soil density, hydraulic conductivity, total porosity, volume of macropores, micropores and cryptopores, humidity at field capacity, humidity at the point of permanent wilting, total availability of water in the soil, hydraulic retention curve and the distribution of soil particles by size.
