The economic effect of applying phosphorus at planting of durum wheat is directly correlated to the phosphorus that is available to the plants from the soil. For bicarbonate soluble phosphorus levels less than 6 ppm, there will likely be a positive economic effect from applying some phosphorus. At this site the soil phosphorus level was 4.8 ppm and the application of 200 pounds of 16-20-0 caused an increase in yield of 2101 pounds per acre. A cost of $23 per acre with a return of $168 per acre.
