Professor Moot was pleased to see the Parliamentary Commissioner for the Environment, Simon Upton, has outlined his concerns about Overseer being used in a regulatory context. Prof Moot has critiqued that report and believes there are also further issues related to the use of this model in farm environmental plans. He believes Overseer is a useful for determining P, K and S requirements on farm but should not be used for assessing nitrate leaching for regulation because it is not capable of doing this in real time. These links will direct you to his letter to Damien O’Connor and his critique of the PCEs report on our Dryland Pastures website..
