Hon DAMIEN O'CONNOR: There are two parts to that. In terms of nitrous oxide, for example, the Government brought in a maximum level of 190 kilograms per hectare of synthetic nitrogen that could be applied. The issue of methane, biogenic methane, nitrous oxide, and carbon dioxide, they all play a different part in the system, they all have different life cycles, and the Government's working on all these particular areas. The issue of stock numbers and stocking rates: it is simply not sensible to have a set figure per hectare across the variants of soil types, of farming systems, and of individual capabilities of the farmers. So we think we're doing the right thing in working with the industry.
