The products of the AUREA line are slow release fertilizers.
They contain Ureic nitrogen fully treated with N (butyl) thiophosphoric triamide (NBPT), a molecule which hinders the urease enzyme.
It is a urease inhibitor and it impedes the transformation of Ureic nitrogen into ammonia (which is highly volatile) through the temporary inhibition of the enzyme.
The urease enzyme, in nature, is produced by fungus and bacteria present in the soil in huge quantities.
Immediately after the application of a top dressing, urea comes into contact with the urease enzyme which produces, by hydrolysis, ammonia carbonate, causing the volatilization of ammonia into the air.
Additionally, due to the hydrolysis, groups of hydroxyl OH are freed up, causing an increase of the pH value, and also resulting in a decline of the alkaline conditions of the soil. The urease inhibitor stabilizes the nitrogen as urea and avoids the rapid transformation into ammonia that would otherwise occur.
Thus ureic nitrogen has more time available to ground in the soil in such a way that volatilizations are notably decreased (it reduces the volatilization of nitrogen up to 50 %, especially important in hot and dry climates).
Moreover as the nitrogen is available to the plants for a longer period of time, the plants can satisfy their needs proportionally in all the critical vegetative stages. This enables an increased yield and quality, permitting less interventions and dosages.
The AUREA fertilizers are environment-friendly products and are in accordance with the European Commission’s directives regarding the reduction of CO2 emissions in the atmosphere.
