American Society for Horticultural Science Experiments reveal best varieties for high salinity soils Earth-Kind® roses are favorites with gardeners and landscapers. Chosen for their superior tolerance to heat, drought, and pests, as well as their outstanding performance in landscapes, Earth-Kind® roses can thrive in most environments, even with limited care. A new study focused on determining the best Earth-Kind® varieties for withstanding the challenges of salt stress. As...

A salt-tolerant variety of durum wheat that outperforms other varieties by 25 per cent on salty soils has been developed by CSIRO scientists using traditional crop breeding techniques. Researchers have introduced a salt-tolerant gene into a commercial durum wheat which has produced spectacular results in field trials. "Salinity already affects more than 20 per cent of the world´s agricultural soils and is an increasing threat to food production due to climate change," CSIRO's Dr...

Australian scientists have bred a variety of durum wheat that can grow up to 25% better in salty soils. Scientists from the CSIRO Plant Industry discovered a salt tolerant gene and, using non-GM breeding techniques, implemented this gene into a commercial durum wheat. The field tests of this crop show remarkable results. Researchers from the University of Adelaide´s Waite Research Institute are leading the effort to understand how this specific gene lends the wheat the ability to...

Could Salty Soil Suck Water Out Of The Martian Atmosphere?

The frigid McMurdo Dry Valleys in Antarctica are a cold, polar desert, yet the sandy soils there are frequently dotted with moist patches in the spring despite a lack of snowmelt and no possibility of rain. A new study, led by an Oregon State University geologist, has found that that the salty soils in the region actually suck moisture out of the atmosphere, raising the possibility that such a process could take place on Mars or on other planets. The study, which was supported by the...

Tomato, watermelon prove most efficient at CO2 accumulation Salt can have drastic effects on the growth and yield of horticultural crops; studies have estimated that salinity renders an about one-third of the world's irrigated land unsuitable for crop production. Imbalances in soil salinity can cause ion toxicity, osmotic stress, mineral deficiencies, and drastic physiological and biochemical changes in plants. Salt stress can even cause plants to adjust their water usage–to conserve...

FIVE POINTS, Calif., Jan. 21, 2011 /PRNewswire/ -- S&W Seed Company (Nasdaq: SANW) today announced that its proprietary, non-dormant, high yield alfalfa varieties marketed as "SW 9720" and "SW 9215" have been renamed "SW 9720S" and "SW 9215S." The added "S" will serve to distinguish and emphasize the varieties as highly tolerant to salty soil and salty irrigation water. The name change has been reviewed and authorized by the California Crop Improvement Association, the seed certifying...

By Michael Byrnes DICKS CREEK, Australia (Reuters) - Farmer John Ive squints through the barbed wire fence separating the roadside from an ulcerous patch of ground where salt has risen from the earth to collapse the land into crumbling, barren ravines. Black stumps from an earlier fence, decayed from the bottom up by salt, dance from wire strands in the biting wind. "These sites are pockmarked across the southern tablelands," says Ive, shaking his head in despair at desertification...

Growing desertification worldwide threatens to swell by millions the number of poor forced to seek new homes and livelihoods. And a rising number of large, intense dust storms plaguing many areas menace the health of people even continents away, international experts warn in a new report. Thick storms rising out of the Gobi Desert affect much of China, Korea and Japan and even reduce air quality over North America, according to Ecosystems and Human Well-Being: Desertification Synthesis. The...

Soil Salinity
2013-04-01 11:15:13

Soil salinity is the salt content within the soil; the process of increasing the content of salt is known as salination. Salt is a natural element of water and soils. Salination can be a result of natural processes such as the gradual withdrawal of an ocean or mineral weathering. It can be caused by artificial processes such as irrigation as well. Soils that are affected by salt are a result of excess accumulation of salts, normally most obvious at the surface of the soil. Salts can be...
