Micro and Macro Nutrient Evaluations on a Putting Green

Foliar tissue evaluations of macro and micro nutrient concentrations were conducted on a mature mixed stand of "Penn A4" creeping bentgrass (Agrostis stolonifera) and annual bluegrass (Poa annua) at the Valentine Turfgrass Research Center, Penn State University, University Park, PA. The objective of the study was to determine if selected micronutrient containing materials could increase the macro and micro nutrient levels in foliar tissue of the turfgrass plant, effect color, and increase growth.
