You guys are going to have to fill me in on the negatives of KCl. I've never heard that KCl was a poor K source for cenitpedegrass. I spent a lot of time in school, a lot of time in the industry, and I've managed a lot of really good lookign centipedegrass lawns (using KCl sources) -- and I've never before heard that KCl sources are bad.
I've looked at unversity recommendations that recommend muriate of potash as a K source for centipedegrass. I've read peer reviewed research that shows that K source doesn't affect centipedegrass quality. I've used muriate of potash for years and never once had a problem.
What do you guys know that I don't? What are you seeing that I'm not?
