Abstract

Herbicide soil/solution distribution coefficients (K(d)) are used in mathematical models to predict the movement of herbicides in soil and groundwater. Herbicides bind to various soil constituents to differing degrees. The universal soil colloid that binds most herbicides is organic matter (OM), however clay minerals (CM) and metallic hydrous oxides are more retentive for cationic, phosphoric, and arsenic acid compounds. Weakly basic herbicides bind to both organic and inorganic soil colloids. The soil organic carbon (OC) affinity coefficient (K(oc)) has become a common parameter for comparing herbicide binding in soil; however, because OM and OC determinations vary greatly between methods and laboratories, K(oc) values may vary greatly. This proposal discusses this issue and offers suggestions for obtaining the most accurate K(d), Freundlich constant (K(f)), and K(oc) values for herbicides listed in the WSSA Herbicide Handbook and Supplement.
