Soil salinity undermines global agriculture by reducing crop yield and impairing soil quality. Irrigation management can help control salinity levels within the soil root-zone. To best manage water and soil resources, accurate regional-scale inventories of soil salinity are needed. The past decade has seen several successful applications of soil salinity remote sensing. Two salinity remote sens...

[1] SMOS (Soil Moisture and Ocean Salinity) is a European Space Agency mission that aims at generating global ocean salinity maps with an accuracy of 0.1 psu, at spatial and temporal resolution suitable for climatic studies. The satellite sensor is an L-band (1400–1427 MHz) aperture synthesis interferometric radiometer. Sea surface salinity (SSS) can be retrieved since the brightness temperatur...

The ice edge of the Barents Sea east of Svalbard is an area where the warm, salty water of the North Atlantic (AtW) interacts with cold, less dense, saline Arctic water (ArW) and the water produced by melting ice (MIW). Many of the CTD profiles (CTD stands for Conductivity-Temperature-Depth) obtained in this region by Norwegian Polar Institute expeditions in 1999 and 2007 contain layers that ar...

Freshwater resources are scarce in desert regions. Highly saline groundwater of different salinity is being used to drip irrigate the Taklimakan Desert Highway Shelterbelt with a double-branch-pipe system controlling the irrigation cycles. In this study, to evaluate the dynamics of soil moisture and salinity under the current irrigation system, soil samples were collected to a 2-m depth in the ...

Salinity-induced modulations in growth, photosynthetic pigments, relative water content (RWC), lipid peroxidation, photosynthesis, photosystem II efficiency, and changes in activity of various antioxidative enzymes were studied in the halophyte Salvadora persica treated with various levels of salinity (0, 250, 500, 750, and 1000 mM NaCl) to obtain an insight into the salt tolerance ability of t...

salinity is one of the most important limiting factors for crops, because of most agronomic and horticultural crops are sensitive to salinity. on the other hands, considerable lands of the world were affected by salinity and they are increasing day by day. an experiment was conducted with five levels of irrigation water salinity in soilless culture and greenhouse condition to evaluate the effec...

introduction: production and growth of plants in many parts of the world due to degradation and water scarcity have been limited and particularly, in recent decades, agriculture is faced with stress. in the most parts of iran, especially in the khorasan razavi province, drought is a fact and water is very important. due to melon cultivation in this province, and the conditions of quality and qu...

abstract seed germination is an important phase of plant development during which soil water availability is crucial. salinity can affect seed germination in two ways: 1) change of osmotic potential of available water, 2) toxicity effects. in this experiment, interactive effects of salinity and water deficit on germination criteria of two species of a, littoralis and a. logopoides were studied ...
