The water balance study in soils with sugarcane, cropped in large areas in Brazil, is essential for the agricultural management to increase the crop productivity and to reduce pollution risks. The objective of this research was to evaluate soil water balance equation components of two Oxisols under sugar-cane (first crop), in the counties of Jaboticabal and Pirassununga, State of São Paulo, Brazil. The study was carried out in an experimental area in Pirassununga (21 º 55 ‘ 54 ” S, 47 º 10 ‘ 54 ” W, 650 m), for only one level […]

Changes in the physical properties of soil, mainly related to water retention and soil aggregation, may be linked to changes in electrochemical soil properties. The purpose of this study was to determine the effects of liming on the relationship between soil and water. In 1994, an experiment was installed in the experimental area of the Departamento de Solos da Universidade Federal de Santa Maria, in a dystrophic plinthic Gray Acrisol. Treatments consisted in surface liming and lime incorporation at 0, […]
