Alfalfa Booster is an alfalfa inoculant that combines two powerful bacteria, Sinorhizobium and Azospirillum, into one easy-to-use formula.  Sinorhizobium encourages nodulation with each application. Azospirillum boosts nitrogen fixation even further while stimulating enhanced root growth, helping plants access nutrients and water more effectively.  Alfalfa Booster comes in a dry seed treatment and a liquid for broadcast application that should be applied after every cut.
