Proper evaluation of soil erodibility factor is very important in assessment of soil erosion. In this study, soil erodibility factor (K) was assessed in a zone, 900 km2 in area in Hashtrood, located in a semi-arid region in north west of Iran. Soil erodibility factor was measured at the unit plots under natural rainfall events in 36 different lands in the study area from March 2005 to March 200...

The Wisdom of Crowds, an innovative theory described in social science, claims that the aggregate decisions made by a group will often be better than those of its individual members if the four fundamental criteria of this theory are satisfied. This theory used for in clustering problems. Previous researches showed that this theory can significantly increase the stability and performance of...

The rehabilitation of sandy desertified land in various dryland ecosystems by different management practices has a great potential to increase aggregate stability and improve soil quality. However, plants in general may have a different ability to sustain soil. The objective was to determine the effects of reclamation practices including Haloxylon ammodendron and Atriplex canescens plantation o...

Soil physical properties have an important role on vegetation growththrough affecting the development of root system. The aim of this study was toinvestigate the trampling effect of livestock grazing on soil physical properties andvegetation cover changes. The experiment was conducted on three range conditionsites (Reference, Key and Critical area) with ten frequencies in HosseinabadeKudistan i...

Research on the variations in soil aggregate stability and ecological stoichiometry at scales by stand type is of great significance investigating distribution, limitation, balance, cycling organic carbon, nitrogen, phosphorus (C-N-P). However, effect pure mixed Chinese fir plantations stability, carbon (OC), total nitrogen (TN), (TP) characteristics still unclear. In this research, we explored...
