Potassium chemical question?

8 years ago
last modified: 8 years ago

I'm looking for a potassium supplement for the lawn? I've seen liquid k25, I've also seen muriate of potassium, potassium sulfate? However I'm using products from N-ext line from green county fertilizer specifically humic12 and air8. Humic12 says its 88 percent potassium hydroxide and air8 says its 5 percent soluble potash. Does potassium hydroxide accomplish the same as a liquid 0 0 25 fertilizer?
