| Abstract/Contents: | "Established perennial grasses require stimulation in order to recycle nutrients, increase light intensity to plants, and improve plant water supply. Perennial grasses that do not receive proper stimulation can result in poor growth and sometimes death. As a result, these areas become susceptible to noxious weed invasion. The purpose of this study is to determine which method best stimulates perennial grasses in order to make them more competitive against noxious weeds. In addition, areas were monitored to determine which treatment had optimum effect on existing noxious weeds. Research plots were established on March 31, 2003 in Adams County, Colorado. In those plots, the majority of the existing grasses were blue grama, western wheatgrass, crested wheatgrass, and sand dropseed with significant leaf litter covering a majority of the plots. Broadleaf weeds included perennial pepperweed, kochia, curly dock, and field bindweed. Treatment methods inlcuded [included] grazing, burning, herbicide applications, and an untreated check. Each treatment was replicated four times in 20 foot by 40 foot plots. Animals used for grazing were sheep and a guard llama. For the controlled burns, the Atarus Ranger propane flamer was used. The herbicides used were 2,4-D at 1.5 pints/acre or 591.4 millileters/liter water and Escort at 1. ounce/acre or 0.75 grams/liter water. Grazing occured [occurred] from April 8 - 12, 2003, burning followed on April 15, 2003, and herbicides were applied on May 12, 2003. Follow-up vegetation surveys were conducted in June and July 2003. It was observed that burning had the best effect on grass stimulation and significantly reduced the amount of leaf litter. The numbers for blue grama and western wheatgrass had significantly increased as compared to the pre-burn vegetative survey. Grazing had a similar effect on the grasses but increased kochia populations had occured [occurred]. Herbicides provided excellent weed control, but grass populations observed in those plots before or after the treatments were lower. In general, burning and grazing have proven to be effective methods at stimulating grass growth in order to provide necessary competition against noxious weeds." |
