I just received the attached from Hummert, and thought it was a pretty good explanation of how pH and Electrical Conductivity affects media quality. With everyone gearing up for spring and summer planting, I wanted to share it.
(P.S.: I'm on a dial-up connection (!) and have placed the settings for the file somewhat smaller than normal to facilitate downloading. The file prints OK, but may not be easy to read on your monitor. If such is the case, I apologize in advance.)
Actually, it's more my eyes, I think!
Thanks for putting this up - when I get done shoveling top-soil, I'll read it!
