Cleveland C. Cleary <br />52773 Ash Rd. <br />Granger, In 46530 <br />Supporting Documentation for APSA-80 vs. Aqueduct Soil Surfactant: <br />The point of surfactants is to lower the surface tension. APSA-80 takes the <br />surface tension down quickly to just over 30 dynes at 30.8 ppm, or about 1 oz. in <br />100 gallons of water. <br />For approaches, tees and greens on golf courses or other heavily trafficked turf, <br />we recommend 1 oz. per 1000 sq ft every month at a cost of $0.43. For active dry <br />spot we recommend 2.5 oz. per 1000 sq ft at a cost of $1.08. For fairways, rough, <br />and other areas we want to keep greener longer we recommend 15 oz. per acre <br />per month at a cost of $6.45. If it is possible to get it on while the turf is still <br />dormant in the spring, we recommend starting with a double dose, then regular <br />doses monthly. <br />The only price I found for comparison for Aqueduct was $260 for a 2.5 gallon jug, <br />so the per oz. price is $0.81 and they recommend 4-8 oz. per month, so at a <br />minimum $3.20 per month. <br />Following is the Aqueduct Soil Surfactant brief; the concentration chart and <br />subsequent surface tension for APSA-80; and a quad fold brochure, the APSA-80 <br />for turf is listed on the last fold. <br />+ 7fP514--90 �.-.-Sa SA' e,,P�t <br />
