Factors driving freshwater salinization syndrome (FSS) influence the severity of impacts and chances for recovery. We hypothesize that spread FSS across ecosystems is a function interactions among five state factors: human activities, geology, flowpaths, climate, time. (1) Human activities drive pulsed or chronic inputs salt ions mobilization chemical contaminants. (2) Geology drives rates eros...

Abstract. The purpose and objectives of the study is to establish levels influence chemistry degree salinity on onset half (LD50) full (LD99) death seeds alfalfa blue hybrid yellow clover. To identify participation each factor in legume using correlation coefficient determination. conduct a comparative assessment salt resistance sweet clover alfalfa. Methods. main natural types salinization cha...

Leaf senescence is one of the most limiting factors to plant productivity under salinity. Both the accumulation of specific toxic ions (e.g. Na+) and changes in leaf hormone relations are involved in the regulation of this process. Tomato plants (Solanum lycopersicum L. cv Moneymaker) were cultivated for 3 weeks under high salinity (100 mM NaCl) and leaf senescence-related parameters were studi...

Wheat is the major cereal crop confronting serious abiotic factors that pose an alarming situation regarding its global biomass production and distribution. Salinization one of those ecological stresses impair growth developmental processes thereby decreasing production. Nearly twenty percent agricultural land encompasses high salt concentration, moreover due to warming even more arable under s...

Arid and semi-arid lands cover more than one-third of the earth’s terrestrial area are typically characterized by rainfall scarcity, higher temperatures evapotranspiration, salinization, nutrient-poor soil, a paucity vegetation [...]

Wetlands, and specially salt marshes, represent the final stage of the filling of depressions, embayments, levelling of marine delta plains and other depositional environments. Due to their origin, they are porous media, with high permeability, permanently flooded, or with very shallow oscillating groundwater table. They are rich in wildlife and among the most primary producers environments in ...

[1] Past land use changes have greatly impacted global water resources, with often opposing effects on water quantity and quality. Increases in rain-fed cropland (460%) and pastureland (560%) during the past 300 years from forest and grasslands decreased evapotranspiration and increased recharge (two orders of magnitude) and streamflow (one order of magnitude). However, increased water quantity...

In experiments carried out in greenhouses, some authors have shown that ammonium sulphate induces greater soil acidity and salinity than other sources of N. Moreover, nitrif ication inhibitors (NI) tend to cause ammonium to accumulate in soil by retarding its oxidation to nitrate. This accumulated ammonium would also have an effect on soil salinity. Consequently, the aim of this paper was to ev...
