Professional athletic field managers maintain trimmed turfgrass with great precision, carefully painting crisp lines and colorful logos on their grass before each game. While these fields appear to be in perfect health, some field managers have noted deteriorating turfgrass beneath repeated paint applications. In a study that appears in Crop Science, three North Carolina State University researchers found that grasses coated with latex paints show a notable reduction in photosynthesis.

Athletic field paint predictably lessens photosynthesis in the grass it covers

Professional athletic field managers maintain trimmed turfgrass with great precision, carefully painting crisp lines and colorful logos on their grass before each game. While these fields appear to be in perfect health, some field managers have noted deteriorating turfgrass beneath repeated paint applications. New research now suggests why. In a study that appears in Crop Science, three North Carolina State University researchers found that grasses coated with latex paints show a notable reduction in photosynthesis.
