Abstract

Using, the soil-water sorption partitioning coefficient (Kd), this study quantified the spatial variation of 2,4-D sorption by soil in an undulating-to-hummocky terrain landscape near Minnedosa, MB, Canada. Herbicide sorption was most strongly related to soil organic matter content and slope position, with greatest sorption occurring in lower landscape positions with greater soil organic matter content. The relation between sorption and slope position was more pronounced under conventional tillage (CT) than under long-term zero-tillage (ZT). Using multivariate regression and three independentvariables (soil organic matter content, soil clay content and soil pH), the prediction of herbicide sorption by soil was very good for CT (R-2 = 0.89) and adequately for ZT (R-2 = 0.53).
