Worth I may try that vinegar idea. I have been adding lots of stuff like manure and cottonseed meal yet my soil remains stubbornly alkaline. I frequently have problems with iron deficiency and have to use iron supplements but sometimes they don't work fast enough.
How much vinegar did you use and on what size bed? I have one area that seems to always give me problems with iron deficiency even though I add some iron supplements to the area every spring before planting.
