Differences between a sterile and a non-sterile product?
Sterile inoculants (peat and liquids) have higher concentrations of pure viable rhizobia. Contaminants are unavoidably high in non-sterile products. Thus, rhizobial numbers are quickly depleted during storage. For this reason, sterile inoculants can be stored for longer periods, and deliver higher numbers of pure (not contaminated) viable Rhizobium cells to the bean crop.
