Initial field testing was performed near our home office in Ohio. The new 18-9-18 Nutri DG dispersing granule was applied side-by-side with a competitors SGN100 homogenous product on Bent greens. Following application of 3.56 pounds of product (per 1000 square feet), the greens were irrigated for 5 minutes.

Following the irrigation, the turf was visually evaluated for particulates, as well as evaluations of ball pick-up, player shoe pick-up and mower pick-up. The results of each are visually shown below:

Then for the ball roll test. Balls were rolled for 10 feet along the greens surface and evaluated for ball pick-up. The images are shown below:
