The spatial variation of arbuscular mycorrhizal fungal spores under the canopy of Acacia raddiana was studied in a desert system. Soils samples from the base of the stem, its canopy radius, and outside its canopy at four stations in the Negev desert were collected from a 0 to 50 cm depth at sections of 10 cm each. The mean spore density was found to fluctuate between 265 100 g 1 to 105 100 g 1 ...

While the effect of soil temperature and moisture on soil CO2 efflux (Ec) has been widely investigated, the relationship between Ec and soil carbon (C), root, and stand parameters has not been comprehensively examined or quantified across extensive spatial and temporal scales. We measured Ec in loblolly pine (Pinus taeda L.) stands located on the South Carolina Coastal Plain across sites, seaso...

Soil samples collected from two major dumpsites each in Kano and Kaduna states were investigated for heavy metals pollution. Each of the dumpsite was divided into north, south, east and west. Four soil samples were collected at a depth of 0-15 cm from each part and pooled to form a composite sample. Soil samples from reserve areas within the same geographical locations as the dumpsites were col...

ABSRACT A study was carried out to investigate the potential of Corn (Zea mays) for phytoremediation of soil contaminated with Cadmium and Lead. Soil samplings of 0-20 cm depth were taken from the Chaharmahal Bakhtiari province in the western of Iran. Corn plantlets were planted in pots containing 3 kg of these soils. The experiment consisted of 9 treatments including soil without cadmium and L...

There have been conflicting reports as to the extent that copper-chromium-arsenic (CCA) treatments leach from timber. In New Zealand, vineyards utilise CCA-treated posts at a rate of 579 posts per hectare. This represents a potential CCA burden on the soil of 12, 21, and 17 kg/ha, respectively, for the three elements. Given a replacement rate of 4% per year, the use of CCA-treated posts may res...

Soil erosion is a global challenge, seriously threatening soil and water resources andenvironmental qualities. One of the important factors to consider in the process of runoffgeneration and soil erosion is the physical and chemical properties of soils under differentland-uses. The aim of this study is to estimate soil erosion and runoff in rangeland, rain-fedand abandoned rain-fed agriculture ...

soil and sediments of the estuaries and wetlands in northwest of persian gulf are recently polluted with different heavy metals because of municipal and industrial wastewaters. therefore an urgent soil cleaning up and remediation program is vital in this region. consequently, this study was initiated to screen two plant species (festuca arundinacea and cynodon dactylon) for hyperaccumulation of...

Increasing of population in the world caused overusing natural resources and land destruction. Salinization and sodification are two effects of land destruction. Leaching of soil soluble salts is the most appropriate method to emend and reclaim saline and sodic soils. In this study, Examination of different leaching methods of saline from sodic soils has been evaluated in Veis Area in Khoozesta...

to find the effect of atriplex canescens on soil chemical properties, two adjacent areas, each with and area of 1 ha, were selected in hossein abad hapeshloo shahryar. in one area it was planted atriplex canescens in 2003 while the later one without atriplex canescens was considered as control area. to sample soil, random- systematic method was used along 3 transects with a length of 100 m. in ...
