A foliar feed designed specifically for macadamias.


Because it is formulated with potassium bicarbonate and unlike the majority of potassium foliar products that are sulphate or nitrate-based, K-Mac has a high pH, and therefore allows for superior potassium uptake.


Potassium is essential to maximise nut size and, with the inclusion of fulvic acid, K-Mac is perfectly balanced to provide required levels along with the essential trace minerals associated with efficient metabolisation once inside the cell.


K-Mac can be foliar applied to a range of nut, fruit and vegetable crops.
