  • Subject: [NAFEX] downside of free potassium source
  • Date: Tue, 08 Mar 2005 05:56:09 -0600

There is another (free?) potassium source, greensand. It was once
spread on a portion of my garden before I moved here. The former owner
wanted a slow-release potassium. The downside is that that portion has a
toxic amount of manganese and some plants do poorly there.
