- Natural source of plant available potassium
- Readily dissolves for use through irrigation
- Low in chloride and safe to use on foliage
- Small particle size for superior solubility

OCP High-K is an organic source of potassium. Potassium is essential to healthy plant growth and crop yields. Potassium deficiency at any stage during a crop’s development can lead to significant yield reductions. Potassium nutrition should be supplied in a form that delivers potassium in the most efficient way for ready assimilation by the plant. OCP High-K is a very high analysis source of potassium with high solubility. It can be applied through irrigation or as a foliar application at any time throughout the crop cycle. This ensures that potassium nutrition demands can be met all season long, removing any chance of a yield-limiting potassium deficiency event occurring.

OCP High-K cannot be mixed with soluble, calcium-based fertilisers. Before applying to sensitive crops, test on a small area first.

OCP High-K is more soluble at lower pH values and most foliar fertilisers work best at a pH of less than 4.5. OCP Maxi-buff Organic water conditioner with built-in pH indicator is ideal for buffering alkaline water. For irrigation systems, check that your water source has low salinity levels.
