Truog P, Bray P, Olsen P, resin P, and surface P were all determined on samples of 17 surface soils from Michigan (from 5 great soil groups), and each soil was cropped in the greenhouse with barley for 4 weeks to determine P uptake and A values. Ca‐P, Al‐P, Fe‐P (by the Chang and Jackson procedure), and organic P were determined on 10 of these soils. Correlation analyses indicate that short‐term uptake of P by barley in the greenhouse was highly correlated with Truog P, while A values, which may be more indicative of seasonal availability, were most highly correlated with Olsen, resin, and Bray P. Organic P and Fe‐P did not contribute to the P removed by any of the measurements. Truog P apparently removed portions of both the Ca‐P and Al‐P fractions, and P removed by cropping was also derived from these two fractions. All the other measurements were highly correlated with only Al‐P.
