Urease and Nitrification Inhibitors are efficiency enhancers contributing to reduce nitrogen losses from fertilisers.

Efficiency Enhancers are a key element of agronomic sustainability: they enable an improved efficiency of fertilising products by ensuring better climate protection and increasing yield potential.

Key Facts

9 M cars

The overall potential impact of inhibitors on emissions from N fertilisers sums up to 32 M tons of CO2 equivalent à equivalent to removing 8.9 M cars from the streets.


NH3 Urease inhibitors reduce NH3 emissions by 70%.


Nitrification inhibitors (NI) reduce N2O emissions by 38% as well as nitrates leaching by 18%.

Why use efficiency enhancers?

Nitrogen fertilisers – just as other fertilisers – are used to boost yields, but only about 50% of the applied N is taken up by the crop while the rest is released into the atmosphere, in deeper soil layer, the ground water and/or fixed at soil particles. These losses pose a challenge for human health, climate and biodiversity. Nitrogen stabilisers such as urease and nitrification inhibitor technologies are one of the solutions to address this challenge.
