Reducing Ammonia Emissions from Urea Fertilisers
REDUCING AMMONIA EMISSIONS FROM UREA FERTILISERS
At the end of March, DEFRA welcomed the proposed alternative approach that will be delivered through the Red Tractor farm assurance scheme and FACTS advisers from 2023.The alternative approach will mean scheme members can:-
- only use untreated or unprotected urea fertilisers from 15th January to 31st March each year
- use urease inhibitor-treated or protected urea fertilisers throughout the rest of the year
Diamond Fertilisers offer N-Shield® fertilisers, which are protected by Limus® from BASF, a unique urease inhibitor which offers a range of benefits to farmers.
REDUCES AMMONIA EMISSIONS BY UP TO 98%
BASF have extensively tested the efficacy of Limus® in both laboratory conditions and in the field, and time and time again it has proven its strength as a highly effective urease inhibitor, reducing ammonia emissions by up to 98%.
INCREASES APPLICATION TIMING FLEXIBILITY
Limus® protected urea fertilisers can be applied independent of weather conditions as they effectively prevent these losses. This not only simpliﬁes fertilisation programmes considerably, it also allows for greater flexibility and a more efﬁcient use of resources.
IMPROVES YIELD BY 5% COMPARED TO UNPROTECTED UREA
Comprehensive sets of replicated trials were carried out by ADAS and BASF to look at the performance of Limus® protected
RAISES PERFORMANCE TO THE LEVEL OF AMMONIUM NITRATE
As part of the wide-ranging DEFRA funded NT26 project, the performance of the urease inhibitor, NBPT (one of the active ingredients in Limus®) was evaluated as an alternative to ammonium nitrate (AN). The project concluded that granular urea plus NBPT matched AN for performance in winter cereals, according to average ﬁgures taken from 10 locations.
As the only urease inhibitor with two active ingredients, Limus® more effectively minimises ammonia losses, ensuring greater availability for crops and higher yields.
STORAGE & STABILITY
The stability of urease inhibitors when added to urea can be limited. Limus® contains BASF patented polymer technology, providing longer a.i. stability versus generic NBPT and 2-NPT formulations. Even at 20°C Limus® is stable for more than 12 months, giving conﬁdence that even if purchased a year in advance, Limus® will still work effectively.
All Diamond Fertilisers are stored undercover to protect the fertiliser and prolong the shelf-life, ensuring the product arrives on farm in pristine condition.
QUALITY GRANULAR UREA
Our Granular Urea is sourced from trusted manufacturers renowned for providing a high quality product. These manufacturers are reliable for consistency in size and for spreadability characteristics.
