Download Determination of the N20 emission factor for animal dung applied in late autumn in three regions of New Zealand

This report presents findings from a field study conducted to determine the nitrous oxide emission factors from application of animal excreta, following application in late autumn 2008 in three regions of New Zealand onto six different soil types. Results enabled the refinement of nitrous oxide emission factors to be determined - EF3 decreases as follows: cow urine > cow or cattle dung = sheep dung.
