20kg Preseed Fertiliser 6-10-6 +3% MgO
This 6-10-6 +3% MgO product is a 20kg pre-seed fertiliser built around a 1:1.6:1 NPK ratio, supplying 10% phosphorus to help newly sown grass seed and new turf establish strongly. Nitrogen comes from both organic and ureic sources so it becomes available in phases as the grass needs it, while potassium and a full range of secondary macronutrients and micronutrients give seedlings everything they need for healthy establishment.
Key Features
- 1:1.6:1 NPK ratio with 10% phosphorus (P2O5) for strong establishment of seed and new turf
- Organic and ureic nitrogen sources for phased nitrogen availability
- Includes potassium plus a complete complement of secondary macronutrients and micronutrients
- Longevity of 8 - 12 weeks
- Suitable for all turf cutting heights
How to Use
- Spread evenly with a suitably calibrated spreader at 25 - 100 g/m², taking care not to overlap or miss areas.
- Where no rain falls within 24 hours of application, water the treated area thoroughly.
- Avoid applying in frosty weather or in very hot or dry conditions.
- Application window: February to May and August to November.
