The effects of varied planting mixtures (native, introduced, mixed), fertilizer treatments, seeding techniques, and irrigation on the microbiological characteristics of soil used in revegetation over retorted shale were investigated using test plots located in the Piceance Basin, Colorado. Over three growing seasons, significant correlations were noted between soil organic matter changes, soil water content, dehydrogenase, phosphatase, N/sub 2/ fixation potential and soil ATP, in relation to specific revegetation procedures. These responses were independent of fertilizer treatments, and soils treated with mineral nitrogen tended to have decreased nitrogen fixation potentials, for which effect at p = 0.06 were noted for the spring 1978 revegetation technique plot sampling. These results suggest that microbiological process monitoring can be useful in evaluating the more subtle effects of revegetation alternatives for surface soil reclamation after oil shale processing.
