Field experiments were conducted in North and South Dakota, with sugar beets and potatoes grown under irrigation, to determine the effect of nitrogen fertilizer additions on the relative availability of soil and fertilizer phosphorus to plants. The addition of nitrogen fertilizer generally increased the percent of the total phosphorus absorbed by plants from bands of concentrated superphosphate. The percent of the total plant phosphorus derived from the fertilizer tended to decrease later in the season. Detailed studies with sugar beets at one location indicate that the percent of the total plant P coming from the fertilizer tended to increase with plant growth.
