Evaluating Revegetation Practices for Sandy Cropland in the Nebraska Sandhills
Journal of range management
Supplemental irrigation generally increased seedling density the sctding year; however, this response was not mah~tained the year following seeding.

This was apparently due to the relatively large proportion of switchgrass (ponicum v&gum L.) in the 2species mixture and its generally poor establishment. The

The reduced seeding rate r-ulted in better stand establishment than the recommended rate on a tilled seedbed (1.1 and 0.7 seedlings/O.1 mz, respectively), while neither seeding rate provided an acceptable stand 00.5 seedlings/O.1 m2) with the no-till treatment in small plot evahmtions. Seedbed tillage also resulted in a higher seedling density than no-tillap (1.3 and 0.5 seedlings/O.1 ma, respectively) for the production-level field Mal. Seedling density was doubled with depth bands (1.2 vs. 0.6 seedlings/O.1 m2). These results suggested that a tilled seedbed on sandy cropland with adequate moisture results in successful stands. A native, warm-season grass mixture (4 or more species) is recommended with a seeding rate of 15 PLS/O.l m2 using equipment with depth bands.
