Western Canadian Product Launch: Polysulphate® Premium

Posted in: Uncategorized
We are eager to introduce Polysulphate® Premium to Western Canada!  Product quality, industry leading seed safety & unparalleled agronomy…


From our 2022 success with delivery, to product quality, industry leading seed safety, and unparalleled agronomy all in a 4 in 1 season long nutrient feeding solution, we are eager to broadly introduce Polysulphate® Premium to Western Canada!  



Over the past 21 years, every innovative solution that we have brought forward that offers great logistics, high level product quality, seed safety and season long feeding for optimal nutrient efficiency, has always brought a return on investment for growers that stepped in and changed their programs.

Polysulphate® Premium is checking all these boxes and grower feedback will allow us to make this a mainstream nutrient solution across a broad swath of acres very quickly. When you bring value and the value is easy to define, a great product is quickly adopted!

Very rarely would you have more than one or two value points with one product but with Polysulphate® Premium there are a tremendous amount of features below that could easily add up to $25-50/acre in value.  

  1. Low salt index with no negative loss of seed compared to S and K in the seed row (tested up to 300 Ibs of product in the seed row). 
    Assume a 15-20% increase in seed survivability which could equate to $15/20 acre for canola.  Assume 100 Ibs of product an acre could work out to just over $30/acre for Polysulphate® Premium and we save more seed. It reduces the overall per acre cost dramatically. Even at $15/acre in seed saving cost, on 22 acres of Polysulphate® Premium applied at 100 Ibs/acre, that is $330 saved for every tonne of Polysulphate® Premium used.
  2. Season long feeding of these essential nutrients for 60 days. Better uptake to demand curves and better finishing of our core crops that need both S and K for filling grain and canola seeds. Assume increases in yield and better quality.
  3. One bin, multiple products – better management of storage.
  4. More storage, less fills to fits today’s logistical needs. Bulk density is high (85 Ibs) as such one bin or one tank on a grain cart holds twice the tonnes. 
  5. Easy & convenient to use. Assume 100-150 Ibs/acre application on average, depending on the crop.
  6. No Nitrogen, which increases seed safety in seed row and allows alternative sources with higher N percentage to be used instead.
  7. Only prilled potassium source in Western Canada. Most growers hate how KCL tears up their air seeder hoses.
  8. Great handling product with low salt index and is not as hydroscopic as AMS and KCL.
  9. Fits today’s market demands of sustainable solutions that make the soil better, crop production better, and increase in nutrient use efficiency which makes the environment better. 
  10. Organic Certified
    Polysulphate® Premium is registered through OMRI as organic around the world but fits conventional growers just as well, meaning it fits growers for today and ten years from now.


  • Efficiency on K and S will improve 25-35% with season long feeding over 60 days vs. all available up front and tie up by day 20.
  • Very low salt index will reduce stress on early plants making them healthier early, which allows them to pick up more nutrients and not delay maturity.
  • Higher plant stand counts in cereals which means more main stems.
  • Expect upside in yield with season long feeding of key nutrients that impact plant growth and filling.
  • Expect higher quality of grains with tight N:S ratios at grain filing and tight N:K ratios to transfer nutrients in the plant at filling.
  • Ca and Mg are secondary nutrients like Sulphur and are required in Ibs/bushel. We need 2 Ibs of Ca to make one bushel of canola.
  • Ca can act as a soft amendment and can tie up a salt when it releases the sulphate. Most all reclamation in the oil field uses calcium to reclaim lease sights.
  • Ca will help crops establish in marginally saline areas but not enough in the blend to correct a fully saline area.
  • We are thinking fertility or nutrition for feeding plants vs applying fertilizer, which plants don’t care for due to salt load.
  • Low N value which allows cheaper options and more flexibility on applying N as ammonia, or as trop dress etc.
