Recently I was in an Albuquerque retail nursery where a fertilizer was being sold that stated it was formulated for alkaline soils of the Southwest. It contained high levels of iron and sulfur, plus the N, P and K major nutrients. Do any of the readers care to comment on this type of product? Pros, Cons, etc. I have my take on it, but I'll entertain what you want to say about it. Michael Martin Meléndrez
