DoubleTop
27N (30SO3)
DoubleTop is a high quality granulated product combining Ammonium Sulphate and Ammonium Nitrate for crops that have a high Sulphur demand
Ammonium Sulphate offers a readily available source of Sulphur to the growing crop. Elemental Sulphur cannot be taken up directly by crops because plants only take up Sulphur in the Sulphate form.
Ammonium Nitrate is the most efficient and predictable form of Nitrogen for UK growers.
A True Granular Compound ensures even and accurate spread across the crop. DoubleTop has the right balance of Nitrogen to Sulphur for the first top dressing.
Applications:
Oilseed Rape - first spring application where early application of Sulphur is required. 375kg/ha product followed by Nitram up to the required N rate.
Winter Cereals - first spring application at 190 kg/ha product followed by Nitram up to the required N rate.
Sulphur Facts
- Sulphur is a very leachable nutrient, where large amounts are required it is advisable to split the recommended requirement.
- Foliar applied Sulphur is a less efficient approach to correcting Sulphur deficiency. This is because only 2% of the Sulphur being intercepted and absorbed through the leaf.
- Average UK deposition of Sulphur is now around 5kg S/ha/year compared with 25kg S/ha/year 20 years ago.
- Sulphur deposition is no longer measured, due to such low levels.
