Abstract/Contents:"Environmental concerns over limited land fill space are leading to the prohibition of compostable organic wastes in land-fill streams. The objective of these studies was to determine suitability of several composts for use as root zone media for sod production with Stenotaphrum secundatum (Walt.) Kuntze. Grass response was better when grown during optimum summer conditions compared to suboptimum winter conditions in Florida. No phytotoxicity from heavy metal content was observed, although soluble salts in a spent mushroom substrate caused intial stunting for a few weeks until daily irrigation leached them for the root zone. Most of 13 compost media were lightweight, high in organic matter, low in bulk density, and had good water holding capacity. Grass grown in a spent mushroom medium produced best grass sod, which required 37 days to produce 50% cover in a summer study compared to 85 days in a winter study. Sods produced on compost root zones were lighter in weight than those produced on sand or phosphatic clay, which weighed 136 and 125 kg mā»Ā², respectively. Seven days after transplant, sod grown in root zones of municipal solid waste compost, perlite-peat mix, spent mushroom medium, sludge compost, and yard trash had equal rooting strength to that of a sand-grown sod. No relationship between rooting strength with growth rate, or with ground cover of grass at time of transplant was found. In spite of dense, intact, undisturbed root systems at time of transplant, only a small percent of total root system was observed to knit with underlying soil. Studies are needed on sod rooting efficiency and function. Most composts used in these studies were acceptable for production of sod. These results warrant additional studies with mixtures of several composts, other soil amendments, and/or different soils."
