A liquid Magnesium fertiliser for foliar application on all types of horticultural crops.


Campbells Trace-it Mg is a liquid fertiliser that is ideal for the correction or prevention of magnesium deficiencies in many horticultural crops. The Nitrogen component of Trace-it Mg assists with effective uptake and transfer of magnesium within the plant.

Magnesium is an essential constituent of chlorophyll and is also involved in enzyme reactions.  It effects the translocation of phosphorus and is involved in water uptake by the plant. Foliar applications can be used to supply ongoing Magnesium requirements or to correct a Magnesium deficiency.

In many cases, soils can have adequate Magnesium levels, however due to unfavourable conditions for uptake via the roots, foliar Magnesium applications are the only option. Trace-it Mg foliar applications work excellently in conjunction with ground Magnesium applications, where demand is high.


Campbells Trace-it Mg is recommended for foliar application.

Caution – Foliar applications should be avoided during extremes of climate and during flowering


Recommended rates of application vary between 2 to 6 L/ha. Specific rates will depend on the crop, stage of crop development and the Magnesium requirement. See the Product Label for comprehensive information on rates and application methods. Before application, seek advice from your Campbell’s distributor or your local agronomist.
