Novurea – NBPT treated Urea

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

Stabilised urea

Every soil contains the enzyme urease. As soon as urea is applied, this enzyme changes urea into ammonium. During this transition there is a local increase in the pH around the granule. If this pH level exceeds 7, part of the ammonium converts to 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 26% on average for surface application.

Novurea: maximum benefit for crop growth

Novurea is urea that has been treated with a urease inhibitor (NBPT). This urease inhibitor prevents volatilisation. 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 ammonium is stable and does not volatilise, making more nitrogen available for crop growth.

Novurea delivers more value for money per kg real crop-available nitrogen than untreated urea. Your investment in nitrogen delivers the maximum benefit for crop growth and limits the environmental impact too.
