THE DECEMBER, 1968 issue of the "Journal of Agriculture" included, as part of an article on the economics of nitrogen fertiliser use, a lift-out section for farmers to complete and return to the Journal.
In the lift-out, farmers were asked to calculate their fertiliser costs and answer a series of questions about the use of nitrogen on their farms.
