What is Origin SUSTAIN®?

Origin SUSTAIN is the new name for KAN.

Origin SUSTAIN is a range of high quality N and NS granular fertilisers manufactured in the UK. It is designed to minimise volatilisation loss associated with the urea form of nitrogen.

Origin SUSTAIN is powered by AGROTAIN® technology and is proven in numerous UK trials.

Origin SUSTAIN stabilises nitrogen against volatilisation loss so it remains available for the crop.


Origin SUSTAIN – Works

A comprehensive series of independent and replicated trials in the UK has compared crop yield from Origin SUSTAIN against ammonium nitrate. Trials have been conducted on full range of crops, including Wheat, Barley, Oilseed Rape, Sugar beet, Potatoes and Grass. Results from the replicated trials have shown Origin SUSTAIN performance is equal to or better than ammonium nitrate.

SUSTAIN has been used by farmers from John O’Groats to Lands End.

Origin SUSTAIN contains AGROTAIN(R), proven to be the most effective urease inhibitor on the market in minimising volatilisation. The active ingredient in AGROTAIN(R) is reviewed and registered by the European Commission.



Summary on Spring Barley AN versus SUSTAIN

AN at 40 kg/ha: 4.81 t/ha
SUSTAIN at 40 kg/ha: 5.79 t/ha
AN at 80 kg/ha: 6.67 t/ha
SUSTAIN at 80 kg/ha: 6.74 t/ha
AN at 130 kg/ha: 7.33 t/ha
SUSTAIN at 130 kg/ha: 7.62 t/ha
AN at 170 kg/ha: 8.07 t/ha
SUSTAIN at 170 kg/ha: 8.35 t/ha

A three-year trial by government agencies in Northern Ireland and the Republic of Ireland showed that switching to SUSTAIN would reduce greenhouse gas emissions by 73% when compared to nitrate-based


SUSTAIN fertiliser gave a 6% increase in Spring Barley yield compared to ammonium nitrate when averaged across all treatments.


Origin SUSTAIN – Spreads

Even and accurate spreading is integral to the overall effectiveness and agronomic performance of a fertiliser, with significant yield losses likely before visual symptoms of uneven spreading are apparent.

Origin SUSTAIN uses high quality, size matched granules with a high crush strength to ensure even, accurate spreading with no nutrient segregation.

The spreader settings and quality of spread pattern of SUSTAIN has been independently assessed across the most popular fertiliser spreaders by experts, SCS.

Origin SUSTAIN – Saves

There are several agronomic, economic and practical benefits to farmers from using Origin SUSTAIN, including:

  • Contains 33% more N than AN. Its higher concentration gives farmers financial savings in transport, storage, handling and spreading compared to AN.
  • Typically lower cost per kg of N than AN.
  • Reduces waste packaging and product handling from using fewer tonnes.
  • No security restrictions associated with transport, handling and storing the product.
