| Abstract/Contents: | "For more than 50 years, surfactants have been used to ameliorate soil water repellency in highly managed turfgrass. This is the first report of synergism between different surfactant chemistries for the enhancement of hydrophilicity in a water repellent soil. The report relates to the discovery that blends of alkyl polyglycoside (APG) surfactants and ethylene oxide-propylene oxide (EO/PO) block copolymer surfactants significantly enhanced aqueous composition infiltration through the matrices of water repellent soil over that obtained with either the APG or the EO/PO block copolymer surfactants alone. When EO/PO block copolymer surfactants were blended in a 1:1 weight ratio with the APG surfactant, enhanced infiltration was observed, particularly at surfactant concentration below 2000 mg L-1. Enhanced infiltration by APG-EO/PO block copolymer blends was also achieved with APG or the EO/PO block copolymer surfactants with limited soil wetting characteristics. These synergistic interactions are a unique property associated with APG-EO/PO block copolymer blends, and were produced by blends when either one or both components alone had limited effect on infiltration. Comparison of commercially available surfactant formulations used to improve infiltration of irrigation water to an APG-EO/PO copolymer blend demonstrated that the blend was more effective than the commercial products tested. Enhanced infiltration of difficult to wet soils by dilute aqueous surfactant solutions is of critical importance in achieving maximum agronomic and/or hydrological benefit when the compositions are used in irrigation scenarios." |
