Fig. 7. Relationship between runoff algal-available phosphorus (AAP) concentration, runoff sediment (SED) concentration, and Bray P1 (B1) soil extraction values. Symbols: ${circ}$ indicates chisel-plowed plots, ${blacktriangleup}$ indicates no-till plots. The AAP concentration = 0.1 + 0.0013B1 - 0.035SED + 4.4 x 10^-4 B1 x SED - 5.7 x 10^-7 B1²; R² = 0.82, P = 0.001.
