The chart I was thinking of is in a book, so I can’t post it, but the article I sent you is pretty thorough.
Nitrogen is good - for things growing ABOVE ground - not so good for root crops, though. Puny potatoes and carrots and radishes, etc.
Ok I will circle back and read the article. The root crops thing makes sense, have never been able to get good carrots or beets. Gave up years ago. Thanks a bunch!
