I tried to find Potassium sulphate, but the only potassium I can find is Muriate of Potash. Is there any reason for concern with the chloride content of the Muriate? I have used it on potatoes and such in the past with no problems, but the strawberries suffered dearly from it. Just wondering how AG's respond to potassium chloride.

It's hot stuff. Lot's of folks have ruined their seasons with MOP aka Potassium Chloride. I sell tons of the stuff this time of year for Ice Melter.

Thanks Steve. I'm going to use it in moderation, ie. 1/2-3/4 cup per 100 square feet. Do you think this is still too much? Should I start with 1/4 to 1/2 cup? I use about 1 cup/100 row feet of potatoes, and just a sprinkle in the onion patch. The only other place I've used it was in the strawberry patch a few years ago. At the 1 cup rate, it was disasterous. It was only later, after investigation, that I discovered strawberries don't like chloride.

Tremor, Quick Question? If you apply the MOP in the fall will that eliminate the chance for injury? Due to winter leaching....

Yes. Some of those salts leach especially in low CEC sandy soils. But likewise some of the potassium will leach too.

I would prefer Sulfate of Potash where quantities of more than 1.5 lbs/M are needed. Though folks have gotten away with more before, the salts will repel worms. Keep this in mind especially where newer patches have had recent additions of organic matter. We want the worms to stay busy working the organic material into humus.
