The article discusses ways to convert unsuitable saline lands into suitable ones using the “Carbon Dioxide Forming Utility Model” and integrated use of desalinating biocomposites. A three-year study proved that among 10 options studied, best restoring soil fertility turned out be 10-9-8 7 options. In these options, savings in wash water, respectively, were according option: 1.46 times; amount c...

Saline soils and halophytic vegetations are common features and part of the habitat pattern in deserts and steppes. The saline area is developing in arid lands. Investigation effects of halophytes on soil characteristics and adaptive mechanisms of the various halophyte types is essential for controlling saline environments. Juncus gerardi is a perennial grass-like halophyte and Halocnemum strob...

The comparative effects of different concentrations of saline soil and saline irrigation water were investigated on growth of canola (cv. Ganyou-5). Plants were subjected to control (non-saline), 0.2% (EC 2.5 dS.m-1), 0.4% (EC 4.5 dS.m-1) and 0.6% (EC 6.5 dS.m-1) of sea salt concentrations in soil as well as saline irrigation water. Vegetative growth parameters recorded were plant height, numbe...

Nearly 40-50% of total global photosynthesis occurring on earth is primarily due to the presence of these algal populations [1]. Microalgae have been identified as a viable feedstock for biofuels due to their efficient capabilities to convert sunlight and CO2 to biomass (which is of great importance for the feed, fuel and chemical industries), can thrive in fresh to saline waters, and the abili...

in recent years, decrease in depth of uromia lake, has resulted in higher increase of salinity threat in agricultural lands around the lake. the aims of this study were 1- investigation of the spatial changes in soil salinity using the bayesian maximum entropy method (bme); 2- prediction of the boundary between saline and agricultural lands; and 3- assessment of the uncertainty involved with sa...

Miscanthus is a woody rhizomatous C4 grass that can be used as a CO2 neutral biofuel resource. It has potential to grow in marginal areas such as saline soils, avoiding competition for arable lands with food crops. This study explored genetic diversity for salt tolerance in Miscanthus and discovered mechanisms and traits that can be used to improve the yield under salt stress. Seventy genotypes...
