Campbells Double Trace is a fully soluble combination of two key trace elements, Zinc and Manganese.
Foliar applied Double Trace can be used where soil applications are ineffective due to high pH, where deficiency has been identified from plant or visual analysis or during peak demand periods, where additional Zinc and Manganese nutrition is required.
