Fig. 3. Comparison of 0.2 mL additions of complete soybean (SB) leachate (____ Control; _ _
_ _ CL-SB) and the acidified leachate (AL) component (...
... AL-SB) on the P sorption of two Oxisols (OX1 and OX2), an Ultisol (ULT) and a Vertisol (VERT) soil after 1.5 h reaction. Significant differences in curves– OX1 curves- Control Psb = 58(±4) log Psln – 2(±5); CL SB Psb = 58(±6) log Psln – 12(±5); AL SB Psb = 60(±4) log Psln + 3(±6)*; ULT curves- Control Psb = 73(±4) log Psln – 25(±5); CL SB Psb = 79(±5) log Psln – 26(±6); AL SB Psb = 75(±3) log Psln – 38(±5)**; VERT curves- Control Psb = 225(±8) log Psln – 19(±8); CL SB Psb = 232(±12) log Psln – 9(±11); AL SB (VERT) Psb = 242(±19) log Psln – 60(±23)** where Psb indicates P sorbed and Psln indicates P in solution.
