USGA Summary Points:The different subsoils, clay loam and sandy loam, are having an effect on moisture content in the overlying sand-cap, which may have implications on the ideal sand-cap placement depth. Although few differences were observed in year 1 due to either irrigation frequency or capping depth, some turfgrass drought stress was observed during 2016 on the 20 cm sand-cap as compared to the shallower capping treatments under 1x/week irrigation. This was most pronounced atop the sandy loam as compared to the clay loam subsoil, likely due to the different physical and hydraulic properties of the underlying subsoil. The Sodium Adsorption Ratio (SAR) is likely to gradually increase from growing season to growing season, which may have a negative effect soil structure and possibly root development within the subsoil as these systems age. Differences in the rate of thatch accumulation suggest that management of organic matter should not be overlooked when managing a sand-cap system, however, a delayed rate of thatch accumulation has been observed with the deepest (20 cm) sand-cap. A 60-day drought will be imposed during summer of 2017 in order to better understand sand-cap x subsoil treatment effects on drought resistance, recovery, and/or survival.
