Abstract: The overall goal of this proposed study is to determine whether or not a mixed coal combustion byproduct generated by the Turk plant in southeastern Arkansas, and similar to the one that will soon be produced by the Flint Creek plant near Gentry, can be safely and beneficially used as an amendment to managed grasslands in northwest Arkansas without negatively affecting runoff water quality. The first sub-objective is to determine how runoff water quality is affected by application of Turks MCCB to established fescue pasture. This will be accomplished in a field study using existing mixed grass plots outfitted with runoff collection equipment. The second sub-objective is to determine the liming potential of the MCCB from Turk. This will be accomplished in a laboratory incubation study. The third sub-objective is to determine the phytoavailability of calcium, sulfur, and environmentally sensitive metals contained in the mixed coal combustion byproduct (MCCB) generated by the Turk plant. This will be accomplished in a controlled greenhouse study.
