Generally speaking, no legume NEEDS to be inoculated just to germinate and grow, only to produce free N within the root nodules. For a deer plotter, you will not be likely to notice the difference either way, as stated above. That said, if you grow an annual legume plot to maturity or are growing a perennial legume, a small pouch of inoculant is a hellava lot cheaper way to add N for next years crop opposed to buying massive amounts of urea. A good inoculated legume crop could provide up to 50% of the N needed for the next crop.
