In relation to FULL, water savings were 40% in SDI and 9% in RDI. Soil salinity (ECe …), chloride concentration (Cle) and sodicity (SARe) measured in the saturation extract of 480 soil samples generally increased in …

mounded under the vine, we tested the effects that various changes to vineyard floor management had on soil salinity and … sodicity, the concentrations of sodium and chloride in leaves and fruit, and yield. Both removal of the under-vine soil mound … salinity of under-vine soils by about 48%. Both rainfall harvesting and re-direction and application of soluble calcium reduced …

salinity and sodicity were generally higher in the more severe RDI than in the full irrigation treatment. Soil salinity and … sodicity generally increased along the irrigation seasons and decreased along the non-irrigation seasons. Salt accumulation or … salinity control. Grapevine yield declined with increases in soil salinity. Leaf Na concentrations were very low (<0.1%), but …

Waters with low salinity and high sodium adsorption ratios (SARs) present a challenge to irrigation because they … degrade soil structure and infiltration capacity. In the Powder River Basin of Wyoming, such low salinity (electrical … over non-irrigated soils (0.1–0.5). Only 8–15% of added Na has accumulated above the drip tubing. Sodicity has increased in …

Density functional theory calculations are performed to provide a molecular-level understanding of the mechanism of mercury adsorption on sulfuric acid-impregnated carbonaceous surface. The carbonaceous surface is modeled by a nine-fused benzene ring in which its edge carbon atoms on the upper...

This paper discusses the rising profile of natural gas in global energy, factors constraining its further development, the gas contracting process, and the absence of a global market, which is analyzed in the context of the economic rent in the gas price and the opaque nature of gas contracts. A...

To maximize the production of biodiesel from soybean soapstock, the effects of water on the esterification of high-FFA (free fatty acid) oils were investigated. Oleic acid and high acid acid oil (HAAO) were esterified by reaction with methanol in the presence of Amberlyst-15 as a heterogeneous...

Crop exposure to salinity can be episodic. The effects on the crop are the sum of those manifest whilst stress … soil salinity and leaf lamina Na+ and Cl− concentrations in previously salinised vines had fallen below the levels … associated with salinity-induced yield loss. Maximum yield loss of 22% averaged over the four seasons was higher than the maximum …

Some earthquakes in the Eastern Mediterranean are tsunamigenic and some of their tsunamis affected the coastal area of the Gulf of Fethiye, SW Turkey. Recent trenching surveys on the low-lying coastal areas of Dalaman delta beach across the Rhodes Pass revealed three probable tsunami impacts as...
