Urea, treated with urease inhibitor NBPTNovurea - NBPT treated Urea

Novurea is a fertilizer containing 46% nitrogen. The green granule is treated with a urease inhibitor, keeping unwanted nitrogen loss to a minimum. As a result, your investment in nitrogen delivers the maximum benefit to crop growth.

Urease inhibitor stabilises urea

Every soil contains the enzyme urease. As soon as urea is applied this enzyme breaks down urea into ammonium. During this conversion there is a local increase in the pH around the granule. If this pH level exceeds 7, part of the ammonium formed is converted into ammonia gas which evaporates, or in other words volatilises. The degree of volatilisation depends on the soil pH, temperature and moisture. Under European conditions the volatilisation is on average 26% for surface application.

Novurea, nitrogen delivers maximum benefit to crop growth

A urease inhibitor prevents this volatilisation. Novurea is urea that has been treated with a urease inhibitor (NBPT). As soon as Novurea is applied the urease inhibitor delays the conversion of urea into ammonium. As a result, the pH around the granule stays below pH 7. The minimal pH rise means that the nitrogen stays in the stable ammonium form which does not volatilise. More nitrogen is available for crop growth. Your investment in nitrogen delivers the maximum benefit to the crop growth and limits the environmental impact too.
