Brief description

Data included in the package;
- standard site weather data (daily)
- soil temperature (50 mm) and surface soil water content (volumetric)
- nitrous oxide flux data, derived from manual chamber measurements (variable time steps) - average for treatment
Experimental design (5 treatments by 5 blocks)
Treatments
* No nitrogen applied
* 50 kg N / ha as urea after every second defoliation (simulated grazing)
* 50 kg N / ha as urea coated with nitrification inhibitor (dicyandiamide) after every second defoliation
* 50 kg N / ha as urea coated with nitrification inhibitor (DMPP) after every second defoliation
* 50 kg N / ha as urea coated with urease inhibitor (nBTP) after every second defoliation

All herbage is removed from plots at each harvest, other fertiliser inputs annually based on soil tests
Experiment commenced in July 2012 on a dermosol (drived from quaternary volcanic tuff and scoriaceous) near Noorat (38.17S, 142.97E)
Objective: To assess the potential for inhibitors to reduce emissions of application of urea to pastures
