I read a link last night from the University of California. They tested drip irrigation methods to see if they clogged with organic fertigation. They found that even with drip tape, organic ferts did not clog the emitters as suspected. They did flush out the lines with pure water after each injection, which might be the difference between it working and not working.
Kelp4less has several soluble ferts that I think would work fine in a EZ Flow, both certified organic and natural. I will need to plumb some valves in order to be able to bypass the injector and switch to straight water at the end of a cycle. I'm not sure I will be able to make that work on a timer, though.
Maybe I can get a truckload of wood chips to mulch the beds, so I can access the drip line more easily than if it were under plastic.
