Popis:	Turfgrass thatch development is a direct consequence of an imbalance between growth and decomposition of organic residues. This study was conducted to determine the characteristics of thatch and the underlying soil in a three-year-old stand of Southshore creeping bentgrass (Agrostis palustris Huds.) and a six-year-old stand of Meyer zoysiagrass (Zoysia japonica Steud.). Intact thatch + soil cores were randomly collected from the two sites for thatch and soil bulk density and total porosity determinations. Disturbed samples of thatch and soil were processed and analyzed for total microbial biomass carbon (C); basal and specific maintenance respiration rates; total C, nitrogen (N) and hydrogen (H) contents; easily mineralizable, soluble, oxidizable and lignin C fractions, and organic matter quality. While the total microbial biomass C content and basal respiration rates were higher in thatches, the specific maintenance respiration rates were significantly lower in soils. Total, soluble, oxidizable ...
