Mapping soil carbon on New Zealand farms

As part of an joint New Zealand/Australian research project funded via the New Zealand Government's commitment to the Global Research Alliance on agricultural greenhouse gases and the Australian Filling the Research Gap programme, New Zealand researchers have produced a new, cost effective technology and method to provide improved estimations of soil carbon stocks on farm.

The project used soil spectroscopy for rapid soil carbon analysis, and provides digital soil mapping for accurate assessment of the spatial variability of soil carbon stocks.

A case study produces a farm scale soil carbon map for Massey University's Tuapaka hill country farm near Palmerston North.
