Effects of Range Burning on Kansas Flint Hills Soil
نویسنده
چکیده
Highlight: Two tallgrass prairie areas burned annually for 20 (grazed) nnd 48 (un. grazed) years ar different fimeS showed differences in soil chemical and physical properties. Winter, early-spring, and mid-spring burned ungrared plots were generally higher in soil pH, organic ma~fer, and K than late-spring burned or unburned plots. Late-Jpring and winter burning lowered soil N on ungrazed and grazed plots. Difference~ in soil nutrient levels though srotisricolly significant probably wm not large enough to affect plant growth.

Long-term Effects of Annual Burning at Dif- ferent Dates in Ungrazed Kansas Tallgrass Prairie - GENE TOWNE AND CLENTON OWENSBY
Ungrazed tallgrass prairie plots in the Kansas Flint Hills have been burned annually at 4 different dates since 1928. Time of burning markedly altered the physiognomy and was the crucial factor effecting vegetation change. Late-spring burning, coinciding with emergence of the warm-season perennial grasses, increased grass production and favored Andropogon gerardii and Sorghastrum nutans. Burnin...
متن کاملEstimating Ambient Ozone Effect of Kansas Rangeland Burning with Receptor Modeling and Regression Analysis
Prescribed rangeland burning in April is a long-standing practice in the Flint Hills region of eastern Kansas to maintain the tallgrass prairie ecosystem. The smoke plumes originating from these fires increases ambient PM2.5 concentrations and potentially contributes to ozone (O3) exceedances in downwind communities. Source apportionment research using Unmix modeling has been utilized to estima...
متن کاملEvaluation of Eastern Redcedar Infestations in theNorthern Kansas Flint Hills
Highlight: Associations among cattle stocking rate, precipitation, and eastern redcedar invasion, and possibly redcedar control measures were investigated. Redcedar numbers generally decreased as stocking rate increased. Precipitation had only a slight effect on invasion rate. Fire, cutting, and fenuron granules appear to effectively kill red cedar. Loamy upland range site consists of soils hav...
متن کاملGrassland bird responses to land management in the largest remaining tallgrass prairie.
Extensive habitat loss and changing agricultural practices have caused widespread declines in grassland birds throughout North America. The Flint Hills of Kansas and Oklahoma--the largest remaining tallgrass prairie--is important for grassland bird conservation despite supporting a major cattle industry. In 2004 and 2005, we assessed the community, population, and demographic responses of grass...
متن کاملEcological Consequences of Shifting the Timing of Burning Tallgrass Prairie
In the Kansas Flint Hills, grassland burning is conducted during a relatively narrow window because management recommendations for the past 40 years have been to burn only in late spring. Widespread prescribed burning within this restricted time frame frequently creates smoke management issues downwind. A potential remedy for the concentrated smoke production in late spring is to expand burning...
