Abstract/Contents: | "Greenwaste from California landscapes has been disposed of in landfills for many years. Legislation now requires reduction of disposal by 25% in 1995 and 50% by 2000. Our goal was to find a sewage sludge (SS) rate which would most enhance yardwaste (YW) amendments. YW was co-composted with (SS) at ratios of: YW:SW 100:0, 95:5, 85:15, 75:25, and 50:50. Fresh YW and composts were blended (30% vol.) with clay, loam and sand soils, added to 3.71 containers and seeded with Manhattan II perennial ryegrass. Germination was greatest in unamended soil, but reduced 50% in soils with the 50% SS amendment, yet this treatment had the best turfgrass color ratings. Clipping yield was highest in sludge amended soils (Chart)." |
