Replication Data for: Final report: Year one: G19-04A – Greens height soil surfactant study – Calcareous sand rootzone G19-04B – Greens height soil surfactant study – Siliceous sand rootzone

This project compares three products from the Aqua-Aid family of soil surfactants and soil enhancers that Ontario Seed Company currently has in their commercially available turf products line-up. These products were compared with an industry standard wetting agent, Revolution, from Aquatrols as a positive control in the study. There was also an untreated control included in the study. The projects were conducted on two newly established putting greens. Project A) was conducted on a putting green constructed from calcareous USGA sand at the new Guelph Turfgrass Institute site. Project B) was completed on a putting green constructed from siliceous sand conforming to the United States Golf Association (USGA) construction method. 2019 results provide a preliminary look at the function/efficacy of soil surfactants, with the goal of examining their long-term effects on rootzone and turfgrass properties over subsequent seasons. Current and future results may also be used by the sponsor for marketing of these products in the Canadian market.
