PhaSed N is a unique blend of SustaiN, elemental sulphur and lime. These materials are finely ground, blended together and compacted into a granule. The combination of the three different products that make up PhaSed N results in a product that delivers performance benefits in excess of those attainable by use of the individual components.
PhaSed N contains 25% nitrogen and 28% sulphur.
PhaSed N is ideal for use in situations where phosphate is not required – or can be omitted – but nitrogen and sulphur are required.
Use PhaSed N on farms where soil Olsen P levels are at or above the economic maximum, but where nitrogen and sulphur applications are needed to ensure the land remains productive.
Hill country is also an ideal place to use PhaSed N. Often it is not cost-effective to apply phosphate to this land, but an application of sulphur will make a big difference to productivity.
Hill country can also benefit from the nitrogen in PhaSed N. As long as airstrips are dry, apply the product in autumn to benefit from both the long nitrogen response and the subsequent sulphur response the following spring.
Trials carried out in Canterbury during the summer of 2008-09 show the pasture performance benefits of using PhaSed N granules compared to using its individual components. When measured against the amount of nitrogen applied, the pasture production response was far higher for PhaSed N, especially on the second cut. This may reflect the slower release of nitrogen from the PhaSed N granules.
