Manni-Plex Cal Mag is based on the unique Manni-Plex technology. Essential plant nutrients combined with a proprietary blend of phloem and xylem mobile sugar alcohols to create a highly efficient foliar fertiliser. The small molecular size of the sugar alcohol carrier together with the spreading and penetrating agents, ensures optimum absorption through the leaf into the phloem and xylem for efficient translocation to the active photosynthetic sinks.
