N-Shield® | How does Limus® work?

How it works

HOW IT WORKS

Limus® is applied to Granular Urea in liquid form. The liquid soaks into the granule, rather than coating it. Simple!

UREASE INHIBITOR

Urease enzymes in the soil convert urea into ammonium. This temporarily raises the pH of the soil around the urea.If the PH spike is not buffered by sufficient rainfall, it results in volatilisation.

Urease inhibitors (e.g. NBPT) block urease enzymes, slowing down this conversion and hence ammonia volatilization

TWO ACTIVE INGREDIENTS

Limus® is the only urease inhibitor available with two active ingredients (NBPT and NPPT), enabling it to bind to a wider variety of urease enzymes, compared to a standard urease inhibitor, thus more effectively protecting the urea from ammonia volatilisation.

This dual-active combination, along with a multi-patented, innovative formulation makes Limus® the most effective urease inhibitor available.

FORMULATION &
STORAGE STABILITY

Limus® formulation contains BASF’s patented polymer technology, providing longer a.i. stability vs. generic NBPT and 2-NPT.

The stability of urease inhibitors when added to urea can be limited. Limus® contains a 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.
