Evolução da qualidade físico-hídrica de um latossolo vermelho-amarelo distrófico em sucessão de uso com mata, mandioca e cacau

Abstract

The perception and quantification of the impact of land use in their physical quality are of utmost importance for the development of sustainable agricultural systems. In this context, this study aims to evaluate the effect of land use systems on physical and water indicators of soil quality. The study was conducted in the municipality of Teolândia, the Southern Bahia region in three areas: native forest, cassava and cocoa. For this purpose, soil samples were collected in the 0 - 0.15m for the evaluation of soil bulk density, total porosity, macro and microporosity, water retention curve in the soil, determination of the S index of soil physical quality, water available and hydraulic conductivity in saturated soil. Tests were also conducted to evaluate the rate of water infiltration into the soil. The results show that the succession assessed in relation to forest, land use with cassava and cocoa changed its physical quality, considering that there was an increase in soil density, reduced macroporosity, total porosity and the volume of water available; these being classified as poor based on the index value S. However, the use of cassava with increased hydraulic conductivity and infiltration of water into the soil.
