“…For given climatic conditions and a particular soil-plant system, both the tillage practice and irrigation system can alter the soil structure (Messing and Jarvis, 1993). Thus, understanding the temporal and management-induced changes that soil hydraulic properties undergo is important for sound land management and for modeling nutrient or contaminant transport (Angulo-Jaramillo et al, 1997;Hu et al, 2009;Yoon et al, 2007).…”

“…At high tensions water retention is due mainly to adsorption to solid surfaces, which depends on properties such as soil texture and the surface area of the particles, and is less influenced by the structure (Yoon et al, 2007). Therefor, the non-useful water pores (permanent wilting point) did not show differences among treatments, varying between 15% and 22% (data not shown).…”

In Copiapó Valley, the 3 th Region of Chile, a three-year study (2007)(2008)(2009)) was conducted to evaluate the effect of organic amendments and cover crops on soil physical properties (Typic Haplocambid) in a table grape (Vitis vinifera) orchard. Four treatments were established during three seasons: control without organic amendments (T1), broad bean-corn-rape rotation (T2), goat manure addition (15 t ha -1 ) (T3) and corn-broad bean-barley rotation (T4). Soils measurements, bulk density, pore size distribution, aggregate stability, water repellence and air conductivity were conducted on soil samples collected at three soil depths (0-10, 10-30 and 30-50 cm). Saturated hydraulic conductivity and mechanical strength were also evaluated. On grape plant measurements, root development, pruning weight and harvested grape production were evaluated. Soil bulk density was reduced with goat manure addition in comparison with any other treatment, which resulted in lower mechanical strength in the top soils. None of the treatments had negative effects on water repellency. The crop treatments enhanced the coarse porosity throughout the soil profile, improving the continuity of porous system with their root development and inducing high air conductivity. Other hand, the control soil and manure application showed a pore discontinuity in a pre-existing plow pan. Aggregate stability and saturated hydraulic conductivity were greater in goat manure application, but the treatments which included crop rotation did not show significant differences compared with the control. Because of the short duration of the study, it is assumed that the soil improvements were not detected as expected in grape production yet.

“…Contrariamente ao método em que é empregado o permeâmetro a disco (Roulier, 1999;Yoon et al, 2007;Kodesová et al, 2010) do anel foi repetido até que a taxa de infiltração atingisse o regime de fluxo estacionário (De Condappa et al, 2001;Souza et al, 2007). Nos pontos escolhidos para os experimentos com o soluto, imediatamente depois de alcançado o regime estacionário, três volumes iguais (100 mL cada) de uma solução de KCl (0,1 mol L -1 ) foram aplicados.…”
