Fertilizer costs have become important factors in crop production in recent years because of (a) increased energy costs associated with fertilizer manufacturing and (b) material shortages. Since this trend will probably continue, it is important that fertilization practices maximize economic returns and fertilizer efficiencies. We have been evaluating the P fertilization needs of some of'the major crops grown in southern Idaho since 1973. This report compares the increased net crop value resulting from P fertilization at different soil test P levels.
