Comparison of novel urease inhibitors under laboratory conditions

Cattle husbandry is the main source of agricultural ammonia emissions. The major part of these ammonia emissions is released from cattle houses. Thus especially strategies to cut the ammonia release on housing level promise to be very effective to lower the emissions. Therefore the aim of this research project is to test the effectiveness of different novel urease inhibitors in order to reduce the urea breakdown, ammonia emissions from animal facilities respectively and to compare their reduction potential to the commercially available urease inhibitor N-(n-butyl) thiophosphoric triamide (NBTPT). A standardised laboratory measuring system is used to detect the inhibitor with the best reduction potential and to study the dose-effect relationships of the inhibitor under laboratory conditions.
