Mr. Bill Callanan:

It does not include banding, but if we look at it in the round, given the area they have, there is certainly availability of other lands in terms of receipt of slurries, which we assume would be one of the things farmers will avail of. We have to be careful. Any modelling is dependent on the assumptions we make, and whether farmers will engage in alternative actions will determine the exact figure. That is what I am saying to the Senator.

For example, a number of years ago Holland brought in a phosphorus quota. That phosphorous quota directly impacted the number of dairy cows, yet their milk volume went up. They took 120,000 cows out of the system and their milk volume went up. It is very difficult. My job is just the science of it and I am not political, but in terms of modelling the impacts of these, we can do them but they all depend on the assumptions we make. That is the point. The volume of milk being produced by our own cows and internationally has grown in terms of processing and so on.
