| The objective of this study was to investigate a particle size distribution (PSD) model to derive saturated hydraulic conductivity. The North Central Texas location is underlain by Windthorst series soil (fine, mixed, active, thermic Udic Paleustalf). The PSD model was compared to double ring infiltrometer values across a conventional tillage component and a low-tillage component. Values of saturated hydraulic conductivity calculated using the PSD model for both the tilled and untilled agricultural region are more time efficient, did not fluctuate so readily over short distances, and maintained statistically significant results that agree with the more time consuming double ring infiltration measurements. |
