Saline Reclamation Solutions
There are over 5.5 million acres of severely salt affected land in Western Canada. When this saline land is in annual crop production, crop yields are often so low that the cost of seed, fertilizer and herbicides are not even covered. Money is lost not made.
Establishing salt tolerant forages on saline soils not only stops the wasting of inputs, it can also result in marginal soils producing valuable feed.
“Watching the yield monitor on your combine at harvest gives you a good idea as to the effect of salinity on crop yields”
As Dave Hoffer farm boss at New Rockport Colony says.
“If salinity is reducing yield then you are much further ahead to square off those areas, seed them down to salt tolerant forages like NewHY and stop losing money”
When choosing a forage mixture to grow in salt affected areas;
- Select a forage mixture that will grow in the salt, soil and moisture conditions present in your field.
- Select a mixture that will meet the needs you have for forage. Is the forage going to be used for hay, pasture, or do you just want it to prevent the movement of weeds into the surrounding land and minimize the spread of salinity.
