Field plots were established in 1978 and 1979 on a Willamette sil (fine-silty, mixed, mesic pachic Ultic Argixeroll) in western Oregon to evalute the effects of chrome tannery wastes on tall fescue (Festuca arundinacea Schreb.) and soil properties. Three rates of waste material were applied each year, N, Ca, Mg, Cu, Cr, Mn, and Zn in soils and plants were analyzed to relate plant elemental concentrations and yield to elemental application and availability. Soil and fescue Cu, Zn, and Mg concentrations varied only slightly with waste application in either year. Soil total Cr levels increased as much as sevenfold with waste treatment; however, fescue Cr concentrations increased only slightly or not at all with waste application. The Mn concentration of tall fescue grown on waste-treated soils decreased compared to that of fescue grown on unamended soil in 1978 but increased with waste application in 1979, reflecting increased soil pH with waste application in 1978 but a decrease in 1979. Both fescue and soil Ca concentrations usually increased with waste application. Soil and fescue N concentrations and soil electroconductivity increased with waste application with the effect still observable 1 year after application. Fescue yields were greatest on soils treated with the highest rates of waste. Yields increased with waste treatment up to 3 years after application. With the exception of stand establishment problems, no detrimental effects of tannery waste on tall fescue were noted in 3 years of study.
