the aim of this research was to determine the effects of camphorosma monspeliaca species on soil nutrient elements in its habitat. for rangeland, ecological positive or negative effects of plant species on environment must carefully be examined before allowing their plantation in vast areas; on the other hand this species with their special characteristics have special effects on their surround...

has always been a challenge in soil mapping (Hole and Campbell, 1985; Hudson, 1992; McKenzie et al., 2000). Some problems in traditional soil mapping—high cost, high subjecTo date defining the soil–environment relationship for tivity, poor documentation, and low accuracy and precision—have motivated the development of a knowledge-based fuzzy soil mapping soil mapping purpose is still largely a ...

Plant productivity is directly affected by the capacity of the root system to forage for soil resources. An enhanced understanding of root-soil interactions provides the potential to improve crop performance in specific soil environments. Interactions between roots and soil are, however, complex. The root-soil environment is heterogeneous and difficult to visualise and measure, root architectur...

Soil contamination due to the compounds of chlorophenols is very difficult to treat. Among the chlorophenols, pentachlorophenol (PCP) is quite persistent in the environment which causes serious pollution problem to the surface and subsurface environment (Berta et al., 2007). PCP, an important class of compounds, is used in many industrial applications, and is found in the effluent and soil asso...

soil organic carbon is a key factor in productivity and quality of soil and environment particularly in semi arid regions. in this article, the role of farm soil organic matter management in soil and in land is discussed. the variability of soil organic carbon in drylands is mainly controlled by tillage and crop residue management. results of this study indicated that usage of correct tillage m...

abstract heavy metals are the most important components of environment pollution. soil contaminated by industrial and mining activities of these elements into the soil-plant-human cycle and accumulate in the human or animal body tissue to reach the levels of toxic for animals and humans. for this purpose, a broad sampling of soil, plant and sheep liver were taken and the amount of pb were teste...
