Wheat (Triticum aestivum L. cv. INIA66R) was grown in a calcareous clay soil, a Torrifluvents from Imperial Valley, California, in containers in a glasshouse. The soil was amended with 450 kg ha/sup -1/ anionic polyacrylamide and 748 mg ha/sup -1/ of coal fly ash in factorial combination. Both amendments increased the vegetative yield of the wheat when applied singly, and when they were applied together the effect was sequentially additive. Without the polyacrylamide, soil was compacted. Large quantities of waste fly ash can be disposed of with little or no environmental hazard through high-level application to land with simultaneous use of a polymer soil conditioner to maintain acceptable physical properties of soil.
