| Technical | Potash Derived from Molasses (PDM) 14.5% K2O min. |
|---|
| Category | Fertilisers |
|---|
| Chemical group | Potassium salts recovered from sugar-industry molasses |
|---|
| Mode of action | Supplies potassium to the root zone, where it governs water movement in the plant and the filling of grain, boll or fruit. |
|---|
| Resistance group | Our grade is the 14.5% K2O PDM notified under the FCO in 2009 and covered by the Nutrient Based Subsidy scheme since Rabi 2022. Note that a separate 50% K2O grade was notified for commercial trials by S.O. 4044(E) of 20 July 2026 — a different product, not this one. |

| Target crops | All crops |

| Target pests / disease | Not applicable — this is a nutrient input, not a crop-protection product. |

| Key benefits | Potassium made in India. The country imports almost all its muriate of potash, and PDM is the domestic alternative — which is why it carries a subsidy. It is a weaker source than MOP by the numbers, so the rate per acre is higher, but it brings organic matter with it and the price reflects the difference. |

| Pack sizes | 50 kg |

| Recommended dose | The FCO sets composition and labelling, not application rate. Note that the notified minimum is 14.5% K2O against 60% for muriate of potash, so a rate carried across from MOP would be roughly four times short. |
|---|
| Water volume | Applied to soil, not sprayed. |
|---|
| Waiting period (PHI) | Not applicable to a fertiliser. |
|---|
| Shelf life | To be confirmed. PDM is hygroscopic — it takes up moisture from the air — so keep the bag closed and off the floor. |
