I have recommended OxyTurf to golf courses that I consult to. All had similar results with the product.
There was no noticeable change in the profile or turf-grass quality after the first application. The second application a month later shows a slight lightening of the thatch layer. The third application a month after this shows a substantial improvement in the colour of the thatch as well as signs of decomposition. The surface also becomes greener as a result of nutrient salts becoming oxidized.
I prefer this product to hydrogen peroxide-based oxygen products as OxyTurf does not have a spike in pH and nutrients do not become over oxidised causing excessive growth. I relate the more consistent performance to the product being of organic origin.
I will continue to recommend OxyTurf to all my clients as I have incorporated it into my thatch reduction constituent of my programs.
