Most likely answer is that muriate of potash is less expensive and better suited to commercial fertilizer while orthoclase is more suited to it’s other commercial uses. When items are used for one commercial use or another, it’s usually a simple case of economics.
The plants take it in better. The absorption is sooner, and therefore it is a more efficient form to use
Well it is a simple and cheap and really soluble chloride salt. It would not have been my first choice for a potassium source unless I wanted to make a cheap fast acting fertilizer. Problem is it has no longevity and that is bad for the groundwater and as soluble as it is (and my guess is the other components are too) any overdose for the plant will do it in fast.
