Saturated hydraulic conductivity ( K s) is controlled by a suite of soil processes operating at various scales. Little known about the spatial variability Ks along slope and how it changed through planting operation process specific scales which controlling factors function. The objective was to characterize scale-dependent relationships between s thereby identify primary s. On typical transect...

Soil infiltration processes manage runoff generation, which in turn affects soil erosion. There is limited information on infiltration rates. In this study, the impact of vine age on soil bulk density (BD) and hydraulic conductivity (Ks) was assessed on a loam soil tilled by chisel plough. Soil sampling was conducted in the inter row area of six vineyards, which differed by the age from plantin...

A field experiment was conducted to study the effect of deficit irrigation and mulch levels on soil physical properties and growth and yield of maize crop. The experiment comprised of two irrigation levels, i.e. I1: 558.8 mm and I2: 711.2 mm while two mulch levels, i.e. M0: no mulch and M15: 15 Mg ha. Soil samples were collected from 0-10, 10-20, and 20-30 cm depths before sowing and at crop ha...

Soil water retention curve (SWRC) and saturated hydraulic conductivity (SHC) are key hydraulic properties for unsaturated zone hydrology and groundwater. In particular, SWRC provides useful information on entry pore-size distribution, and SHC is required for flow and transport modeling in the hydrologic cycle. Not only the SWRC and SHC measurements are time-consuming, but also scale dependent. ...
