Fig. 1. Effects of incubated soybean (SB) or Rhodes grass (RG) leachate and P applied on the P sorption after 1.5 h of an Oxisol (OX1) soil (^____ Control; SB: ^{_ __ _} 0.2 mL, ^...... 2 mL; RG: ---- 0.2 mL, ^{... ...} 2 mL). Significant differences in curves- Control: P_sb = 101(±14) log P_sln – 69(±29); 2 mL SB P_sb = 141(±17)*log P_sln – 98(±31) where P_sb indicates P sorbed and P_sln indicates P in solution.
