DairyNZ are modelling N leaching under urine patches from cows fed different pastures.The soil moisture data from the Scott Farm eddy flux site will be used to calculate daily average air filled porosity of the soil.  Air filled porosity influences urine infiltration into the soil and hence urine patch size, which in turn influences N leaching. Therefore daily average air filled porosity values will improve modelled N leaching estimates. 
Modelling efforts are still underway and no manuscript has been prepared yet.
