Continual rolling when cutting and the effects of air-born silt will create surface sealing on fine turf. This can lead to decreased infiltration rates and a reduction in gas exchange between the atmosphere and the root zone upper horizon. Regular use of the ATT Sarel roller prevents surface sealing with minimal surface disruption. An excellent tool for use after top-dressing to help integrate the sand into the turf canopy. Can be used up to 25mm depth.
