the effects of saline groundwater on soil properties and yield of three range plants in saline soils
the use of saline groundwater resources, in addition to save fresh water, could be used in production of forage in saline soils. in order to do it, the area in northern ardakan, yazd province with saline ground water (ec= 11.25ds/m, sar= 16.7) and saline and alkaline soil (ec=27.3ds/m, esp= 30.2%) was selected for planting of atriplelentiformis, seidlitzia rosemarinus, and nitraria schoberi. th...
gol-e-gohar iron ore mine of sirjan in southern part of iran is a large open pit that operates below the groundwater table and during mining operation, dewatering is required to prevent operation processes from flooding. current operation is going on by digging wells in or out of the pit and pumping to prevent flooding. as a result of the former dewatering operation a vast deep cone of depressi...
abstract environmental pollution has made urban citizens to focus on landscapes. in this respect lown is very important plant. from the other hand water resources in many arid and semi-arid region is saline. for this purpose a research was conducted to study the effect of sprinkling irrigation with saline water on growth parameters of three lown varieties. these varieties were poa partensis, fe...
the aims of this study were to evaluate the treatment efficiency and effectiveness of vetiveria zizaniodesof two samples of unconventional water of golgohar mining and industrial company. the experimental samples were included mine wastewater and saline ground water. this research was conducted in a greenhouse at central water research laboratory of university of tehran. this experiment was des...
synthetic envelopes have been found to be highly effective filters for numerous applications and are currently replacing gravel envelopes. the growth of petrochemical and textile industries in iran offers the possibility of manufacturing these products domestically. the objective of this study was to assess the mineral clogging potential of two non-woven synthetic envelopes (pre-wrapped loose m...
BACKGROUND Road traffic deaths are a considerable public health problem and a major source of lost financial and human resources. Most mortality occurs in low- and middle-income countries. OBJECTIVES This study aimed to measure road traffic fatality rates and years of lost life, and also to depict a view of trends in road traffic deaths from 2004 to 2010 in Yazd city, a province in central Ir...
The ability of hydrogels to absorb large amounts of water implies that they both provide less soil water losses by preventing deep percolation of water and also increase water use efficiency of plants leading to decrease the effects of water deficiency due to salinity stress on crops. To study the effect of two types of superabsorbent (Stockosorb and Xanous) on growth of greenhouse cucumber und...
batiaghata upazila, khulna district in south-west coastal region of bangladesh is the mostly saline affected area, where agriculture activities are mainly dependent on rainfall. 23 water samples from surface water and shallow tube well (stw) were collected in the monsoon season and analyzed for physico-chemical properties to classify them according to salinity hazard. electrical conductivity (e...
Groundwater is one of the most important water resources in Fars province. Based on this study, 95 percent of the total annual water consumption in Fars is used for agriculture, whereas the percentages for domestic and industrial uses are 4 and 1 percent, respectively. Population growth, urban and industrial growth, and agricultural development in Fars have created a condition of water stress. ...
