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...

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 erosion by water is the main factor of land degradation, particularly in semi-arid regions where soil productivity is usually low and lowering soil quality can severely decrease crops yields. this study was done in an area of 900 km2 in the semi-arid agricultural region of hashtroud in northwestern iran to determine the relationship between soil productivity and soil erodibility. wheat gra...

Impacts of land use on soil organic C (SOC) are of interest relative to SOC sequestration and soil sustainability. The role of aggregate stability in SOC storage under contrasting land uses has been of particular interest relative to conventional tillage (CT) and no-till (NT) agriculture. This study compares soil structure and SOC fractions at the 30-yr-old Horseshoe Bend Agroecosystem Experime...

Abstract: Ridge culture is a special conservation tillage method, but the long-term influence of this tillage system on soil aggregate-size stability in paddy fields is largely unknown in southwest of china. The objectives of this paper are to evaluate soil aggregates stability and to determine the relationship between SOC and soil aggregate stability.Soil samples at 0-20 cm layer were adopted ...
