I think the news media sometimes loses sight of the fact that one day my sons and nephews will carry on this business. This land is like a big savings account to me, and I want to protect that account. A consultant tests the soil and decides what extra nutrients the Warrens crops will require. Because nitrogen, potash, phosphorus, herbicides and insecticides all are very expensive, the applications are calculated to such a degree that the crop zeros-out those elements. This allows for the added environmental benefit - no excess nutrients.
Efficiency is everything.
There is no room for error in farming.
