For those of you who have played the last week or two, you might have noticed some white specks of product on our putting greens. Its a greens grade fertilizer with IBDU slow release fertilizer technology. It is one of the standard products used to put greens to bed in the winter. The release mechanism for this fertilizer is water which is abundant in the late fall and winter in our part of the country. As our greens freeze and thaw during the winter, this material will breakdown and will migrate into the thatch/mat layer of our greens. Some material could move into our soil layer which is 3-5" below the green surface and will be held by the soil. As the soil temperatures begin to increase in late winter and early spring, the material will become available to the plant. Our turf will green up quicker from this late season application and will assist the plants in recovery from our early season aeration program we utilize in March.
