Pay the extra money for the Peas. Unless you have a large area to plant....over 10acres....soybeans will let you down if you have any deer pressure at all. Soybeans will stop growing and die as soon as the terminal bud is eaten out of it, and deer usually do this to the plant before it ever gets over 5" tall. A Pea just sprouts more and more stems and leaves the more it's grazed.I think I've found a place to get soybeans for $20 a bushel. Peas are a little high.
