A review of a novel enzyme system for the management of thatch and soil water repellency in turfgrass

Managing soil organic matter is a crucial component of greenkeeping and turfgrass maintenance. Organic accumulation as thatch major problem in modern management. Additionally, water repellency (SWR) caused by hydrophobic coatings on sand particles can create serious infiltration potential runoff problems contribute to reduction turf quality playability. Lignin acts protective matrix limiting microbial degradation cellulose hemi-celluloses. This article reviews lignin structure its unique oxidation mechanism that makes it suitable for use systems the research progress develop laccase tool manage layer SWR. A series experiments explored direct application fungal produced enzymes degrade lignin, speed degradation, thereby reduce accumulation. Greenhouse studies provided proof concept confirmed impact physical chemical properties thatch. Field verified effectiveness different species optimized rates frequency. The thickness treatments was similar reductions achieved cultural management greater occurred when applied combination with other ameliorate SWR laboratory field studies. Single applications were effective reducing but not wetting agents. Enzyme combined agent provide maximum relief Application core-aeration topdressing could number mechanical cultivations necessary keep layers at desired levels Laccase nondisruptive approach highly managed turfgrass.
