There is a major new report out called “Status of the World’s Soil Resources”. Chapter 15 is titled “Regional Assessment of Soil Change in the Southwest Pacific”. Very catchy, I know but there is a wealth of information here about NZ soil status if you like to get down and dirty in this area.
There are familiar NZ names in the contributors (and credits):
“Regional Coordinator/Lead Author: N.J. McKenzie (ITPS/Australia) Contributors: J.A. Baldock (Australia), M.R. Balks (New Zealand), M. Camps Arbestain (ITPS/New Zealand), L.M. Condron (New Zealand), M. Elder-Ratutokarua (Secretariat Pacific Community/Fiji), M.J. Grundy (Australia), A.E. Hewitt (New Zealand), F.M. Kelliher (New Zealand), J.F. Leys (Australia), N.J.
