4. Effects of runoff harvesting through semi-circular bund on some soil characteristics

M. Heshmati; M. Gheitury; M. Hosseini

Volume 4, Issue 2 , Spring 2018, , Pages 207-216

http://dx.doi.org/10.22034/gjesm.2018.04.02.008

Abstract
  In this study, to investigate the effects of runoff harvesting on soil properties in the semiarid forest, runoff harvesting through semi-circular bund was considered as a method to conserve soil and thereby combat tree mortality. In order to evaluate this hypothesis, runoff was harvested through the ...  Read More
