WIL-GRO® CONTAINER PREMIX 2023 is a quality, slow release fertilizer
blend containing 20% calcium, 2% magnesium and 3 different soil buffering
sources. It has a full complement of N-P-K, minor elements, and 78% of
the nitrogen is in a slow release form that is released primarily by microbial
activity. The buffering agents differ by sizing to maintain a consistent pH
stability over time. Developed as a potting premix for nurserymen, it offers growers a simple, one component premix for making a potting media base capable of supporting a wide range of ornamental plants.
