AIRTEK® is the result of the collaboration between
Belor and BASF
Why Belor chose BASF's Limus® inhibitor
Urea enzymes are not all the same!
Urea is an enzyme produced by plants and soil organisms, whose structure can vary depending on its origin and depending on the bacteria and fungi that populate and develop it. Thus, for a diverse typology of soils, we have urease enzymes that differ in structure or dynamics and the speed of the urea hydrolysis process.
To inhibit different enzymes we need different inhibitors!
In fact Limus®, our inhibitor of choice for the AIRTEK® product line, combines the effectiveness of two different inhibitors: N-butyl triphosphoric triamide (NBPT) and N-butyl phosphoric triamide (NPPT) in a ratio of 3 to 1.
The AIRTEK® range of products developed with the Limus® inhibitor, invented and patented by BASF, drastically reduces, for a determined period of time, nitrogen losses through the volatilization of ammonia into the atmosphere because it manages to intercept and inhibit the largest possible number of enzymes of wishes with different structures. Therefore the availability of nitrogen for crops increases.

Urea inhibitor and urea function
inhibited with Limus® from BASF
AIRTEK® products inhibit the activity of urease enzyme for a determined period of time, reducing the volatilization of Ammonia (NH3). Limus® is a BASF brand urease inhibitor and has the role of slowing down the activity of the urease enzyme, reducing the volatilization of ammonia, having a low impact on the environment.
For this reason, Belor confidently chose Limus® technology, giving life to the new AIRTEK® product line.
Limus® is one of the most effective urease inhibitors in the world that is applied directly to urea, being the first of its kind in Romania. It has both a role in nitrogen stabilization and an inhibitory role.
Administration of AIRTEK® in the field
The urease enzyme has an activation zone where it fixes urea and in the presence of moisture converts it to carbon dioxide and ammonia, thus making the activation zone available again for the transformation of a new molecule of urea.
The job of the urease inhibitor is to occupy the urease enzyme activation zone, shown in the diagram below, for a set period of time, preventing ammonia from volatilizing and actually increasing the amount available to crops.

Benefits
Reduces volatilization of ammonia from urea
Increases the amount of nitrogen available to plants, inhibiting urease enzymes in the soil
Reduces fertilization costs
Provides efficiency and flexibility in nitrogen fertilization programs
Limus® advantages for farmers
Lower losses mean more nitrogen available to plants, which increases production potential
Nitrogen is available to plants in critical stages of crop development
High returns on investment
More flexible application of fertilizers, independent of weather conditions
Excellent support for farmers for sustainable agriculture
