SustaiN reduces the amount of nitrogen lost to the atmosphere by 50%*, compared to standard urea. SustaiN is a granular urea product, coated in AGROTAIN®: a patented nitrogen stabiliser (NBPT source). This means SustaiN provides a more effective use of nitrogen for your pasture or crops, one of the most important nutrients for plant growth. SustaiN can be used all year round, with no need to wait for rainfall.

*Halves the amount of nitrogen lost as ammonia, compared to urea. Results may vary based on specific soil and environmental conditions (eg. Soil organic matter, temperature, moisture and pH).

Apply less but grow more, for better returns

• SustaiN mitigates nitrogen losses to increase nitrogen efficiency and provide a more flexible application schedule.
• SustaiN can help boost pasture production and improve crop yields.
• SustaiN has even-sized granules, so it's easy to handle and spread.

Ease of use

• SustaiN is suitable for a variety of conditions, with no need to wait for 10mm of rainfall within 8 hours of application

Supports sustainability

• 50% less nitrogen lost to the atmosphere as ammonia gas*

Directions for use
The most reliable responses to fertiliser N occur when the plant is actively growing (e.g. for pasture, when grass is 40-50 mm in length with adequate time (3-6 weeks) allowed between application and subsequent grazing).
Nitrogen response will not be maximised if soil temperature, moisture or lack of other plant nutrients is limiting plant growth. The optimum timing for fertiliser N applications is when soil temperatures are above 7 degrees.

Livestock safety
Warning: Short pre-grazing intervals may expose livestock to potentially unsafe levels of urea. Do not graze animals if visible fertiliser is present on pasture.
It is an offence to feed this product to animals.

Crop-safety
This product may include up to 1.5% biuret. Some crops are sensitive to urea or biuret specifically, seek advice before using SustaiN for the first time on a crop (or at higher rates or different timing than used previously).

Compatibility
SustaiN can be blended with other Ballance fertiliser products immediately prior to application. Consult your Ballance Agri-Nutrients Ltd technical advisor prior to blending to ensure only suitable Ballance products are used that are compatible with SustaiN. The SustaiN application rates/ha and timings must not be exceeded when applying in a fertiliser blend.

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

Keep out of reach from children and pets.
In event of emergency call 0800CHEMCALL (0800 243 622).
