| Key benefits | Bulk organic matter for soils run on chemical fertiliser alone for years. It is not a nutrient product — the FCO asks only 1.2% of N, P and K together — it is a carbon product. What it changes is structure and water holding, so the same irrigation goes further and the fertiliser you do apply stays where the roots are. |

| Pack sizes | 50 kg |

| Recommended dose | The FCO sets composition and labelling, not application rate. The rate for this product should come from the state agriculture department or an agricultural university recommendation. |
|---|
| Water volume | Applied to soil. Broadcast and incorporate before sowing. |
|---|
| Waiting period (PHI) | Not applicable to a fertiliser. |
|---|
| Shelf life | Store dry. The FCO caps moisture at 25% and the bag has to still meet it when it is opened. |
