At both sites, recharge is not restricted significantly by chemical limitations (e.g., no accumulation of salts that could result in degradation of water quality), topography or water-restrictive features in the root zone or deeper soil profile, such as hardpan or claypan. For both sites, the root zone residence time and deep percolation ability were the most limiting characteristics due to relatively high clay content.

These correlated properties have a significant effect on water and nutrient-holding capacity, drivers of crop yield, and hence can be used for delineating productivity zones for claypan soils (Jaynes et al., 1995; Kitchen et al., 2005).
