Determinants of Soil Loss Tolerance for Rangelands1
- J. Ross Wight and
- F. H. Siddoway2
Rangelands, which occupy about 40% of the earth's surface, have been increasingly recognized as an important and often mismanaged natural resource. Accelerated erosion is recognized as a major problem associated with the management of this vast resource. Attempts to extend the concept of soil loss tolerance (T value), as developed for cropland, to range ecosystems is of questionable validity. The fragility of rangeland ecosystems, the irreversibility of erosion damage, and the large margins of error associated with soil loss estimates make it difficult to develop T values for rangelands.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
