Reduce Ammonia Emissions - How does Limus® work?

Limus® minimises urea volatilisation by temporarily inhibiting urease enzymes from converting urea into ammonia – until the urea has been sufficiently washed into the soil.

If you want to stop profits escaping, start by choosing N-Shield® fertilisers protected by Urea.

Nitrogen can be lost as ammonia following the application of Granular urea. UK research suggests average ammonia losses from Granular Urea applied to arable land are 22%, ranging from 2% to 43%. The amount of nitrogen lost is dependent on environmental conditions post application. Important factors include soil moisture content, rainfall and temperature.

Limus® can reduce these losses by up to 98%, improving nitrogen use efficiency on farm, whilst reducing ammonia emissions.

What makes Limus® unique?

Urea is not readily plant available and first needs to be converted into ammonium. This is done by urease enzymes in the soil that bind to the urea. Without sufficient rainfall post application, the ammonium concentration around the urea granule increase, leading to a localised increase in soil PH. This converts the ammonium to ammonia gas.

Urease inhibitors temporarily bind these enzymes, preventing the localised pH to spike and reduce the losses of ammonia. However, different urease require different urease inhibitors. Limus® is the only urease inhibitor on the market with two active ingredients (NBPT and NPTT) enabling it bind to a wider variety of urease enzymes and more effectively minimise losses.
