Hi. At a friends table in SK. 7500 acre farmer north east of Regina. Lots of wet weather last number of years. Some parts of wet areas turning white with no crop. 5 years ago those areas grew crops. How will the CB work to enhance these areas back into production? Franc and his crew are coming to field day if you can respond with your expertise prior would be great! Thanks

I suspect that sodium content in your friend's soils is the source of the white color. I also assume the problem areas are the lower elevation in the field.
The other assumption is that we have a density layer which is perching water in the upper portion of the plow layer.
If my assumptions are all correct then I suspect the more abundant rainfall has moved the sodium in greater than normal amounts downward to lower spots in the field. Ideally there would be no lateral movement of the water and therewith the movement of the sodium would be harmlessly downward.
So the way I read the situation is fairly straightforward. Restore water movement downward from the location where it lands on the soil surface. This is precisely what the CurseBuster Eagle tine uniquely makes happen.
Unfortunately the soil chemical make up has now been altered with the influence of the sodium. Fortunately under the influence of calcium sulfate or gypsum surface applied to the problem areas we can fairly quickly adjust the chemical balance back to where it should be for normal plant performance.
The unknown now is how much calcium sulfate or gyp is required. I strongly suggest using Perry Ag Labs in Bowling Green, MO for the testing. Secondly, I suggest analyzing only the top three inches of soil.
Lastly, if gypsum is not readily available, then calcium carbonate can be combined with ammonium sulfate in suquential but separate applications to create the same effect and often at lower cost. The desired magnesium content in the limestone product will depend on the exchangeable mag content reported on the test results.
Let me know if I have made incorrect assumptions and may the Lord be you guide. Jim Martindale
Afternoon Carl we have been working with the sodic soils in Alberta and and SK in SK we have developed a remediation program that has shown positive results in plant establishment and yeild agreeing with Jim that water movement is critical. Our approach is to re mediate the root zone with a planter/drill application along with improving the biological profile to mobilize more calcium to the soil water solution.in severe situation we will add a broadcast application material is called Infusion 810.
