It seems that at least a few people on here have had dealing with Mark and they have all said he really knows his stuff, I'm curious what has he offered in terms of advice that was uniquely different than anyone's else or available literature? Particularly how a person would save on costs, for instance I already use "brown bag" seed and not fancy blends with a deer on the bag, I try to rotate legumes to gain free nitrogen, and have started to no-till as much as possible to help overall soil health.
