Survival And Growth Of Wildflowers With Buffalo Grass Or Blue Grama Grass, Dale T. Lindgren, Daniel Schaaf
Survival And Growth Of Wildflowers With Buffalo Grass Or Blue Grama Grass, Dale T. Lindgren, Daniel Schaaf
West Central Research and Extension Center, North Platte
Two studies in west-central Nebraska to determine the survival of wildflowers planted with buffalo grass [Buchloe dactyloides (Nutt.) Engelm.] and blue grama grass [Bouteloua gracilis (H.B.K.) Lag. ex Steud.)] were conducted in 6 and 10 year studies. In total, 19 forbs and 1 grass were transplanted with ‘Texoka’ buffalo grass in the first study, and 16 forbs were planted in a split-plot design into 3 buffalo grass selections, blue grama or a clean cultivated plot in the second study. Survival between transplants in both studies varied significantly. In the first study, survival was significantly higher for little bluestem …

Wind is the principal driver of the Wind Erosion Prediction System (WEPS), which is a process−based computer model for the simulation of wind−blown sediment loss from a field. WEPS generates wind using a stochastic wind generator. The objectives of this study were to improve the stochastic generation of wind speed and direction and to update the wind statistics used by the generator with statistics derived from more recent, quality−controlled data for the 48 contiguous states of the U.S. Erosive wind power density (WPD) was chosen to evaluate how well wind is generated, since it is proportional to sediment …
