Fact Sheet on Revegetating Saline Soils Now Available

A new fact sheet put out by the Saskatchewan Forage Council (SFC) will help producers return land with saline soil to greater productive capacity by using grasses.

Saline soils are those which contain sufficient soluble salts to impair productivity. In Saskatchewan, saline soils are generally rich in sulphate salts, existing as compounds of sodium, magnesium and calcium.

Agriculture and Agri-Food Canada (AAFC) estimates that about 5.52 million acres of agricultural land in the province are at moderate to high risk of salinization. Depending on the level and type of salt present in the soil, the impact on crops can range from minor yield reductions to establishment failure.

Given those factors, SFC Executive Director Janice Bruynooghe said the fact sheet, entitled "Revegetation of Saline Soils Using Salt-Tolerant Grasses," serves an important purpose.

"We've got some pretty vast acres in parts of Saskatchewan which have saline soils with sufficient soluble salts to impair productivity. Sometimes it's not an entire quarter-section that is affected, but smaller chunks and pieces here and there," said Bruynooghe. "Producers struggle with these areas, getting them seeded down and being productive."

However, the good news for producers is that moderately to severely saline soils can be reclaimed using salt-tolerant perennial grasses. In fact, new grasses have recently been developed that have improved salt tolerance, yield and quality compared to grass species traditionally used for saline soil reclamation.

"If we can get those areas established, forages can work to mitigate some of the salinity within the soil," Bruynooghe said. "The land can be reclaimed, while at the same time providing a forage crop that can yield a financial return for the producer from land that might otherwise be unproductive."

The fact sheet gives an overview of soil salinity and the problems it poses for plant growth. It provides a comprehensive rating of grasses that are commonly grown in Saskatchewan, highlighting their relative salinity tolerance, growth and production characteristics, and resulting forage quality. It also contains management considerations for producers to bear in mind when using grasses for saline soil reclamation.

"It's an excellent summary of some of the challenges and the resources available that producers might look at using," Bruynooghe said.

Funding for the publication was provided through AAFC's Greencover Canada Program. Project partners included AAFC, Saskatchewan Agriculture and the SFC.

Copies of "Revegetation of Saline Soils Using Salt Tolerant Grasses" are available online at http://www.saskforage.ca/, or by calling the SFC office at (306) 966-2148.

The SFC was formed as a co-operative in 1987 to enhance the province's forage industry in terms of production, harvesting, utilization and marketing. It plays a role in communicating information to producers and others in the industry, dealing with government on production issues and marketing policies, and assisting in the identification and prioritization of important research.
