Abstract/Contents:"Differential rates of N ranging from 2 1/2 to 12 lb/1000 square feet applied annually to several turfgrass species suggests that soil pH is more directly involved in thatch accumulation than the N levels. A direct relationship was implicated between soil pH and the silica content in the resulting thatch. Since an inverse relationship was shown between turfgrass silica content and thatch decomposition, environmental and biological factors that increase silica content will greatly increase turfgrass thatch accumulation. The commonly accepted relationship between increased thatch accumulation with increasing levels of applied N fertilizer, was not observed under alkaline soil conditions. The data from our studies showed that thatch accumulation was approximately 2 times greater under alkaline conditions (pH 7.0-7.5) compared to slightly acid soil conditions (pH 5.8-6.5). In addition, increased silica content in turfgrass vegetation resulted in an apparent reduction in transpirational water loss. This suggest that increased silica levels in turfgrass may enhance the efficiency of water use."
