摘要

Creeping bentgrass (Agrostis stolonifera L.) putting greens are core cultivated multiple times annually to minimize excess organic matter and maintain surface firmness (1). This abrasive process induces turf stress and is traditionally conducted during periods of active growth to ensure rapid recovery and minimize surface disruptions. Although turf managers routinely apply fertilizer before and/or after coring to promote healing, research-based recommendations for nutrient applications are lacking. Besides nutrients like nitrogen, phosphorus, or potassium, many managers routinely incorporate plant hormone supplements from seaweed extract or humic acid into their programs. These supplements, or biostimulants, are added because they have been demonstrated to improve bentgrass stress tolerance (3). Information directly comparing traditional fertilizers and the potential benefit of biostimulants for alleviating stress and enhancing recovery after coring would prove useful to turf managers.
