The authors have developed an elaborate simulation program to measure the results achieved in crop production and farm income of the use of any operating procedure in any environment. Because this
program has proved useful not only for the analysis of ...AND THE DESERT SHALL REJOICE, but also for irrigation managers who have an opportunity today to choose from among alternative operating procedures, it has been
published separately. Part Two was originally published by the United States Department of Agriculture as Technical Bulletin Number 1431, (1971, rev.1978) and is again available, with the program instructions, contained
on a disk that is affixed to the text for use on either a personal or mainframe computer.
