NZAGRC comment - Should this have an acknowledgment to NZAGRC funding in it?
PGgRC comment - Approved. Some interesting results but I agree with Gerald on where this might lead to, is it going to be cost effective to pump the methane from sheds into the soils . Will South Island soils have similar properties to Dairy No1 - mainly alluvial. 
MPI - comment - The conclusion could be better rather than just noting need for further research. Needs some quantitative results.
