abstract soil quality is an essential concept for maximum agriculture production without environmental destruction. studying soil physical quality indicators, that express soil structural stability and soil air-water balance in root zone, is one of the most important aspects of soil quality. so determination of optimal range for pore volume distribution is important and this research carried ou...

application of superabsorbent material is one of the new methods for moisture storage in the soil. this research was performed in the khajeh research station on the basis of randomized complete block design with three replications in the plots with dimension of 4×5 meter for investigate the effect of different amounts of pumice on water retention capacity in the soil, growth and of spring saffl...

In this article, we consider the implications of the 'Prevent' strand of the government's counter-terrorism strategy for the UK state's engagement with Muslims. We argue that the logics of Prevent have been highly problematic for state-Muslim engagement. Nevertheless, we suggest that the characterisation of state approaches to engaging Muslims as a form of discipline is incomplete without an an...

Temporal and spatial variations in the water status of walnut trees (Juglans regia L.) and the soil in which they were growing were traced by analyzing the differences in hydrogen isotopes during spring and summer in a 7-year-old walnut stand. Walnut root dynamics were measured in both dry and wet seasons. Walnut roots were mainly distributed in the upper soil (0-30 cm depth), with around 60% o...

due to limitation of available water and soil resources in iran, the challenge of optimizing the utilization of these resources has become more significant. one of the solutions to the economic, planning and optimization of water use and achieve the optimum level of water use is associated with improved farming activities and this is the most important agricultural research needs. the study of ...

Climate change makes people to be aware about the environmental pollutions in aspect of Air, Water and Soil components. The environmentally aware countries have forced the other countries to implement the stringent effluent standards for disposal into water stream / water bodies. Hence, modern technology like the application of membrane separation (Micro or Ultra filtration) technique with biol...

Heavy metal pollutions of soil is one of the serious problems in the mining tailing areas, therefore, it is significant to estimate heavy metal of soil in the mining tailing areas. This research take Jinduicheng Mo mining tailings, Huaxian, Shaanxi Province as the study area. A total number of 288 soil samples collected at the mining tailing areas. And the heavy metal concentrations of Pb in so...
