End of March 2023, DEFRA clarified the regulations with using urea fertilisers and as originally planned, farmers must use urease inhibitor after April 1st 2024.

In conjunction with BASF, we have been producing N-Shield fertilisers protected by Limus for the past 4 years in the anticipation of DEFRA regulations.

We chose to partner with BASF, to ensure our urease based fertilisers are tried and trusted, with solid data and trial results to support farmers to grow more sustainably.

Limus® from BASF is a dual active, innovative urease inhibitor. And rigorous ADAS Agronomics trials and BASF testing prove it's an innovation that works. By reducing ammonia losses, Limus® delivers equivalent yields to AN and increases the yield of Urea by 5%.

What makes Limus® unique?

** Reduces ammonia emissions by 98%

** Raises performance to the level of AN

** Improves yield by 5% compared to standard Urea

Limus^® is the only urease inhibitor available with two active ingredients enabling it to bind to a wider variety of urease enzymes resulting in less ammonia lost, making Limus^® the most effective urease inhibitor available. The formulation of Limus^® is based on patented BASF polymer technology which provides longer active ingredient stability compared to generic formulations and under normal UK conditions the Limus^® treated urea has effectively a two year shelf life.

Trevor Needham, one of BASF’s Real Results 50 growers based in Nottinghamshire, took part in a tramline trial in conjunction with Thomas Bell & Sons Ltd, comparing ammonium nitrate with Limus^® protected urea - Diamond Fertilisers N-Shield^® Granular Urea 46%N.

Mr Needham said, “My main reason for taking part in the trial was to see if protected urea could become a cost-effective source of nitrogen for us. The trial field is a very light sandy site and I have always considered urea unsuitable for our sand land, particularly in dry years, like this one, because of volatilisation. However, if we can get some efficient use from N-Shield then this may bring back a cheaper source of nitrogen to us.”
