Merbabu 15 — 30 — 15

Merbabu 15 — 30 — 15 + 2MgO + TE with high P levels is part of our Balkan Greenhouse/Horticentar Water Soluble NPK range.
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.

Product characteristics

• 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

* Depending on the amount of water used.
In case of foliar feeding as part of a spray-mix, testing the intended spray-mix on a small area is recommended prior to commercial
treatment.
The mentioned indicated dosages, number of applications, concentration and application stages are subject to soil and climatic
conditions, influence of previous crops and other specific conditions. Exact dosages, concentrations and application stages can only
be given after an objective diagnostic procedure by e.g. soil, substrate and / or plant analyses.
