OP-T-K Phosphate & Potash Unlocker
Releases bound P and K already in your soil.
A microbial consortium of phosphate-solubilising and potassium-mobilising bacteria. Most South African soils are sitting on decades of locked-up phosphate fertiliser; OP-T-K unlocks that legacy nutrition at a fraction of the cost of fresh P application.
