Effects of burning, intensive clipping, and late season nitrogen application in the northern tallgrass prairie
Invasive exotic cool-season grasses such Kentucky bluegrass (Poa pratensis L.) and smooth bromegrass (Bromus inermus Leyss.) have reduced native grasses in the northern tallgrass prairie. The objective of this study was to determine the effects of spring burning, intensive clipping, and late season nitrogen application on species foliar cover. Experimental sites were established near Brookings (restored), Miller (native), and Volga (native) in eastern South Dakota. The experimental design was a split-split plot with 4 replications. The whole plot consisted of spring burning or no-burning, the subplot consisted of weekly clipping to 5-10 cm in May, and the sub-subplot consisted of June application of 0 or 15 kg/ha nitrogen. Foliar cover estimates of major plant functional groups were conducted in late-June/early-July and late-August/early-September.
