Latest Soil salinity Stories
Earth-Kind® roses are favorites with gardeners and landscapers.
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.
Australian scientists have bred a variety of durum wheat that can grow up to 25% better in salty soils.
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.
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.
FIVE POINTS, Calif., Jan.
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.
Rising dust storms a health problem, even continents away; infant mortality worst in drylands.
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...
