| The main purpose of this work was to estimate soil physical characteristics that are time consuming, developing mathematical models based on others characteristics obtained routinely on soil laboratories. Thirteen soils were selected varying from 40 to 590 g kg-1 of clay content. From these soils, undisturbed and bulk samples were obtained at 5 cm to 15 cm soil layer, and determined in laboratory, chemical (sorptive complex, pH and potential acidity) and physical (bulk density, dessorption curve and porosities) characteristics. Correlation was established among optimum soil water content and soil water at field capacity and the chemical and physical soil characteristics obtained. The soil characteristic that showed the highest correlation coefficient... |
