A root zone for natural grass of sports fields (planted surfaces) based on suction applied to a water control system has been developed and patented. Controlled water management by surface and/or subirrigation, conservation, and suction removal is automatically regulated by soil moisture sensing. The availability of sports fields for scheduled events regardless of weather is enhanced and wear tolerance increased. The Prescription Athletic Turf system is patented by Purdue Research Foundation as USA 3908385, 13 SE 75 and Canada 985516, 16 MR 76.
