• Effects of Range Burning on Kansas Flint Hills Soil

      Owensby, C. E.; Wyrill, J. B. (Society for Range Management, 1973-05-01)
      Two tallgrass prairie areas burned annually for 20 (grazed) and 48 (ungrazed) years at different times showed differences in soil chemical and physical properties. Winter, early-spring, and mid-spring burned ungrazed plots were generally higher in soil pH, organic matter, and K than late-spring burned or unburned plots. Late-spring and winter burning lowered soil N on ungrazed and grazed plots. Differences in soil nutrient levels though statistically significant probably were not large enough to affect plant growth.
