Damp grade ferrous sulphate heptahydrate provides 20.4% iron as supplied. It is highly cost effective so presents an economical way of applying iron. Solubilised readily in cold water prior to application for green up and ‘hardening off’.
- Highly cost effective iron source
- Greens up and ‘hardens off’
- Good solubility grade with relatively low impurities
Dissolve in water prior to spray application. Apply every 3 – 6 weeks as required. Apply to dry turf. Do not apply over frost.
| Zone | Ferrous Sulphate Heptahydrate | Water Volume | Area | Notes |
|---|---|---|---|---|
| Golf Greens/Tees/Fairways/Sports Pitches | 5-10 kg | 150-600 litres | 1 hectare | Over application can lead to scorch and blackening of moss |
| Bowling Greens | 750g-1.5 kg | 22-90 litres | 1500m² |
Product should be keep dry and part used bags sealed back down to remain air tight when in storage. Ferrous sulphate undergoes slow oxidation in water at pH values above 3 – this generates a fine precipitate over time – this should not block nozzles if spraying is concluded within 4 hours of preparing any solutions.
