Nrich SOA is a widely used fertiliser that is manufactured overseas and imported into New Zealand.

Nrich SOA is frequently used alone, but it may be blended with non-reactive fertilisers, e.g. Nrich Urea, MOP, DAP and Serpentine Super.

It must not be blended with lime, dicalcics or dolomite, as there is a risk of ammonia gas being produced.
 

Nrich SOA (sulphate of ammonia) is a source of nitrogen and sulphate sulphur and can be applied after winter to replenish the mobile sulphur which can be lost through the soil's profile after rainfall.

Benefits
• Ideal for strategic nitrogen applications to pastures in early spring.
• A first-choice product when soils have suffered from minor flooding or waterlogging.
• Dust-free with even-sized granules for ease of handling and spreading.

Directions for use
Nrich SOA is suitable for broadcasting or aerial top-dressing to pasture, crop or soil. It is not suitable for drilling or mixing with seed.

Nrich SOA should be applied in early spring in situations where soil sulphate-sulphur levels are low enough to limit the pasture production response to nitrogen applications.

Low soil sulphate occurs when conditions promote leaching of sulphate from the soil. This is most pronounced in winter, when rainfall rates are highest.

Storage information
To maintain product quality, Nrich SOA should be stored in cool, dry conditions and should not be stored for a prolonged period.

Keep out of reach from children and pets.

WARNING - Avoid placement near waterways.
For detailed advice on good fertiliser spreading practice, see the guidelines in the Code of Practice for Nutrient Management, which can be downloaded from fertiliser.org.nz.
