Serpentine Super 15K is blended with muriate of potash to create a general-purpose maintenance fertiliser that is ideal for use in a range of pastoral situations.

The high proportion of citric acid-soluble phosphate in these products make them useful in conditions where phosphate run-off is a concern.

The use of muriate of potash means these products are not suitable for use on chloride-sensitive crops.
