| Abstract/Contents: | "Thatch is commonly associated with the use of intensive management practices on turfgrasses, because thatchiness is often indicative of the vigor of growth for that grass. But many of us have also had to address thatch accumulations of turfs that receive very low levels of management. These turf ares are seldom irrigated, limed or fertilized, adn are therefore often inhospitable to the activities of microorganisms in the thatch layer. Low management turfs often also have lower levels of leaf, stem, and root production than found in high management turfs. Smith (1979) predicted that at tissue production rates below a certain broad minimum, the amounts of decomposer microorganisms will become restricted by insufficient carbon, and that plant litter will begin to accumulate. At production levels above the minimum the amounts of tissues produced simply outstrip the ability of the microorganisms to keep it decomposed. These principles, illustrated in Fig. 1 B, indicate that a moderate level of management may be best adapted for control of turfgrass thatch. More research is obviously necessary, but there appears to be no reason to believe that thatch is only a hight management problem." |
