2014 meeting of the Agricultural Inventory Advisory Panel

Papers considered

Four papers were presented to the panel for consideration:

Recommendations regarding EF₃ emission factors and methodology were not approved. The panel decided further clarification of values and methodologies was required for points 17 and 18 of the paper.
The panel agreed to the recommendation to alter point 19 of the IPCC 2006 guidelines regarding urea.
Regarding the nitrogen retention paper, the panel:

did not agree with the recommended updates to (a) and (b) N retained in liveweight gain: cattle and sheep as they were not well-backed by the reporting
were concerned about adopting (c) N retained in liveweight gain: deer as the recommendation was based on a study which included deer not prevalent in New Zealand
suggested changes should be made to (d) dairy cattle % crude protein of milk
were concerned about (e) beef cattle % crude protein of milk as it contained data from breeds not found in New Zealand
agreed with the recommendation in (f) sheep % crude protein of milk but asked that additional analysis be done
recommended (g) deer % crude protein of milk be calculated from breeds prevalent in New Zealand
accepted (h) N retention in wool, provided the figure in the paper is quoted from the ARC report
noted that recommendation (i) N velvet % needed to account for the conversion factor for dry matter
accepted recommendation (j) deer growth period.

Copies of the papers presented to the panel, and the minutes taken, are included below.
