using of saline water for irrigation of crops is known as a strategy of on-farm irrigation water management. in this study, the cyclic using of saline and fresh water and its effect on soil salinity were investigated. field experiments were carried out in randomized complete block design under drip irrigation for maize crop with 9 treatments. the treatments were based on alternative irrigation ...

karkhe watershed (kw) with more than 5 million hectares recently encountered many problems in the natural, social and man-made habitats. unsuitable use of land, soil erosion and lack of rainfall are the most destructive factors in this watershed affecting the whole region fundamentally. as expected, these problems have caused a considerable fall in biodiversity in fauna and flora, a decrease in...

BACKGROUND La Sal del Rey ("the King's Salt") is one of several naturally-occurring salt lakes in Hidalgo County, Texas and is part of the Lower Rio Grande Valley National Wildlife Refuge. The research objective was to isolate and characterize halophilic microorganisms from La Sal del Rey. Water samples were collected from the lake and a small creek that feeds into the lake. Soil samples were c...

[1] The Columbia River plume (CRP) is an ecologically important source of nutrients, pollutants, and fresh water to the Oregon/Washington shelf. It is traditionally undersampled, with observations constrained to ships or moorings. High-spatialand temporal-resolution observations afforded by satellites would increase sampling if the plume could be quantitatively detected in the imagery. Two empi...

in order to investigate the effects of saline waters on some soil characteristics, this experiment was conducted with three irrigation water salinity treatments contains 1.7-3.4, 8-9 and 11-12.5 dsm-1 (low, medium and high salinity) and two irrigation water managements with four replications in a wheat-fallow-sugar beet-safflower rotation. results show that in (1) irrigation management with low...

As a consequence of increasing urbanization and shortage of good quality water, wastewater irrigation is a growing phenomenon in many arid and semi-arid countries. A common characteristic of wastewater is high salinity, with cities typically adding 200 – 500 mg l of total dissolved solids compared to the source water supplied to the city. Wastewater from the city of Hyderabad in southern India ...

The demand for salinity-tolerant turfgrasses is increasing due to augmented use of effluent or low-quality water (sea water) for turf irrigation and the growing turfgrass industry in coastal areas. Experimental plants, grown in plastic pots filled with a mixture of river sand and KOSAS(R) peat (9 : 1), were irrigated with sea water at different dilutions imparting salinity levels of 0, 8, 16, 2...

Freshwater environments are at risk of increasing salinity due to multiple anthropogenic forces including current oil and gas extraction practices that result in large volumes of hypersaline water. Unintentional releases of hypersaline water into freshwater environments act as an osmoregulatory stressor to many aquatic organisms including native salmonids like the Arctic grayling (Thymallus arc...

Salinity intrusion is a significant issue in the San Francisco Bay Delta because this estuary contributes substantially to fresh water supply for much of northern California. Traditionally, salinity along the estuary has been measured using monitoring instruments installed at various locations within the Sacramento-San Joaquin River Delta system, and these measurements are used to predict futur...

We conducted a retrospective study of serum biochemistry and hematologic findings from displaced, out-of-habitat bottlenose dolphins (Tursiops truncatus) exposed to various low salinity environments in waters along the southern United States including southeastern Atlantic and northern Gulf of Mexico. Serum sodium, chloride, and calculated osmolality were significantly lower and below reference...
