[QUOTE="NorCalFarms, post: 258690, member: 2465"] Alfalfa is tough for sure. Two things that kill it out early (around here anyway) are low PH (or really really high for that matter) and standing water in the winter or in the summer when it is hot. We routinely have stands last in the 7-9 year range. Low fall dormancys for this area (2'sand 3's) last longer but the yeild is less. It seems to like the PH in the 7 range but we have ground from 6.5 to 8+ that will grow good alfalfa. I've heard of roots going 30 feet or more, in loose soils. I know I've dug trenches for pivot wire and found roots at 6' that were big and healthy and still going down. If you have good submoisture and the fertility is right, it doesn't surprise me at all. Alfalfa likes P and K. I've hayed rental places that had a good stand of alfalfa, made 6 tons/year that were well over ten years old. Rough as all heck, but still growing hay. [/QUOTE]
