limits legume establishment and persistence on summit and toeslope positions (Guretzky et al., 2004; Harmoney Legumes establish and persist on backslope landscape positions et al., 2001). but fail on summits and toeslopes in southeastern Iowa pastures, suggesting that these pastures be managed site specifically. Visual Visual delineation of where one landscape position delineation of landscape ...

groups, although the difference in NDF at reproductive stage was attributed to the difference in maturity. At Neutral detergent fiber (NDF) concentration is related to intake reproductive stage, the low-NDF groups also had lower potential of forages but might also be related to plant reaction to yield per plant than the high-NDF groups; at the vegetapathogens. Three smooth bromegrass (Bromus in...

Seasonal time of switchgrass (Panicum virgatum L.) harvest affects yield and biofuel quality and balancing these two components may vary depending on conversion system. A field study compared fall and spring harvest measuring biomass yield, element concentration, carbohydrate characterization, and total synthetic gas production as indicators of biofuel quality for direct combustion, ethanol pro...

Grass tetany is a complex metabolic disorder that causes substantial livestock production losses and deaths in temperate r gions of the world. It is caused by low levels of Mg or an imbalance of K, Ca, and Mg in forage consumed by animals. Development of grasses with improved mineral balance would be an economical means of minimizing losses from this malady. This study was conducted to determin...

and even under grazing produces significant levels of viable seed that end up in the soil (Chapman and AnderWhite clover (Trifolium repens L.) populations persist for years in son, 1987; Charlton, 1977). grazing lands primarily through clonal growth, yet retain high genetic variability. This study was conducted to determine how clone structure In spite of the presence of viable white clover see...

Garrison creeping foxtail can increase the forage yield of wet meadows. However, tillage can be problematic on heavy-textured soils and thick sod mats often associated with wet meadows. This study examined the potential of establishing Garrison with the use of herbicides and no-till planting. Garrison was no-till drilled into a wet meadow using herbicide control of existing vegetation in the en...
