Understanding the spatial soil salinity aids farmers and researchers in identifying areas in the field where special management practices are required. Apparent electrical conductivity measured by electromagnetic induction instrument in a fairly quick manner has been widely used to estimate spatial soil salinity. However, methods used for this purpose are mostly a series of interpolation algori...

Plant growth and yields are decreased by salinity, drought and other environmental stress conditions. Soil salinization is one of man’s oldest environmental disasters. The historic records show that many human civilizations declined because of the destruction of crop production by salinization of arable lands. Recent estimates suggest that about 20-25% of the world’s irrigated land is destroyed...

Two selections of bread wheat, Triticum aestivum L., differing in their relative salt resistance, were grown in salinized solution culture, and relative growth rates, osmotic adjustment, ion accumulation, and photosynthesis were monitored to study the responses of the plants to salinity.Differences in water relations were minimal and were only apparent for 3 days following salinization. The lin...

Astragalus membranaceus Bge. var. mongholicus (Bge.) Hsiao (A. mongholicus, family Leguminosae) is one of the most important traditional Chinese herbs because it contains lots of bioactive metabolites, which have beneficial and pharmacological effects on health. Simultaneously, it has been proved to be a salt-tolerant plant-one of the potential species to control the soil salinization. Therefor...

Climate change will bring about rising sea levels and increasing drought, both of which will contribute to increasing salinization in many regions of the world. There will be consequent effects on our crops, which cannot withstand significant salinization. This Special Issue looks at the roles that can be played by halophytes, extremophiles that do tolerate salinities toxic to most plants. In a...

Waterlogging and salinization arise in arid areas largely because two essential resources, irrigation water and the assimilative capacity of unconfined aquifers, are not priced or allocated correctly to reflect scarcity values and opportunity costs. Farm-level and project-level models of crop production are examined to identify policies that will encourage farmers to consider opportunity costs ...
