Dr. Elaine McGoff:

It is not where we want to end up. Denmark, which has quite high stocking density, is improving water quality but it has moved to house systems. None of us in this room want to end up with cattle housed indoors. It is much more nitrogen efficient but it is bad for an awful lot of other reasons. It is not a very good magic wand solution but if you want to address nitrates and keep the same stocking density, that is where you end up.
