N-Shield® fertilisers are protected by Limus®, a unique urease inhibitor, which offers a range of benefits to farmers. The application of Limus® to Granular Urea minimises volatilisation and adheres with guidance in the government’s Code of Good Agricultural Practice for Reducing Ammonia Emissions.

At the end of March 2022, 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.

Nitrogen losses to the environment are significantly reduced, so more remains in the soil available for plants, which can therefore improve yields.

Limus® Nitrogen Management helps support optimal nitrogen availability for more consistent yields. The combination of two active ingredients (NBPT + NPPT) in Limus® brings higher crop yields than urea with NBPT as a stand-alone active ingredient.** With Limus®, the yield performance of urea is raised to the level of AN fertilisers.

1. Reduces Nitrogen Losses

2. Increases yields by 5%*

3. Higher Nitrogen Availability
