Abstract/Contents:"Soil water repellency occurs on sandy turfgrass soils as localized dry spots (LDS) and within the dry area of fairy ring disease areas. Soil water repellency causes serious soil water infiltration/runoff problems and reduces turf quality. Our research explores a new and novel approach to alleviate soil water repellency by using direct application of enzymes that are specific for degradation of hydrophobic organic fractions believed to contribute to soil water repellency. Since these enzymes directly degrade or alter the organic coatings, they should provide for longer-term and more effective alleviation of soil water repellency than the current management approach that involves repeated use of wetting agents. The objectives of this research were to refine application protocols through laboratory experiments that determine the most cost-effective enzyme application rate and application frequency for the treatment of soil water repellency/LDS. The addition of laccase at a rate equivalent to 8 units / cm2 improved water retention, 8.5 % above that of the untreated control and rates of 12 and 16 units / cm2 greatly improved water retention, increasing soil moisture content by 23 and 25.9 % respectively over that of the non-treated control."
