Abstract: Abstract Phosphate and glyphosate molecules compete for sorption sites in soil. The objective of this study was to quantify the impact of Olsen P concentrations in two contrasting soils on phosphate and glyphosate sorption. Soils were a sandy clay loam soil rich in iron oxides (SCL-Fe2O3) and a clay loam soil rich in calcium carbonates (CL-CaCO3). The phosphate Freundlich sorption coefficient (Kf) ranged from 3 to 68 L1/n mg1–1/n kg− 1 in the SCL-Fe2O3 and from 21 to 76 L1/n mg1–1/n kg− 1 in the CL-CaCO3. Glyphosate sorption coefficient...
