- Highly efficient source of Phosphate (P).
- To be used during specific critical growth stages.
- Highly soluble, pure, free of dust and with limited sensitivity for caking.
- Low on sodium and chloride.
- Trace elements are fully chelated.
- Specially designed for foliar feeding.
- Specially designed for fertigation in soil as well as high tech, soilless.
- Compatible with most water-soluble fertilizers, except fertilizers containing Calcium. In this case, two tanks are required or fertilizers should be applied separately.

Function of NPK 15 30 15
Merbabu 15 — 30 — 15 + 2MgO + TE is recommended when high rates of Phosphates (P2O5) are required by the crop during specific critical growth stages. E,g. during periods of intensive root growth or during the generative stage of the crop when bud formation, flowering and fruit setting is done.
