Knowledge on soil hydraulic properties such as water retention and hydraulic conductivity curves is indispensable for water and pollutant transport modeling of agricultural systems. This soil hydraulic properties are affected by numerous sources of variability, mostly associated with spatial, temporal, and management-related factors. The objective of this study was to analyze the spatial variability of parameters of water retention (van Genuchten) and hydraulic conductivity (Brooks & Corey) curves obtained with the “Beerkan” method based on simple infiltration experiments and soil […]
