Hon DAVID PARKER: That will be a decision for the next Government, after the election. In the meantime, there is a new input control which puts a limit of 190 kilograms of synthetic nitrogen to be applied per hectare per annum. This is estimated to require a change in practice from an estimated 20 percent of dairy farms—80 percent of dairy farmers already meet this standard. The package also strengthens the existing nitrogen toxicity attribute in the National Policy Statement for Freshwater Management by requiring protection of 95 percent of vulnerable species from the toxic effects of nitrate levels, up from 80 percent in the current national policy statement.
