Velocity constants were determined for the reactions undergone by atrazine, chlorpropham, diuron, linuron and picloram in the presence of various amounts of soil and water at 95°. the rates of reaction were dependent on the quantity of soil present but not on the extent of adsorption. At high ratios of soil: herbicide the rates were sufficiently fast to suggest that non‐biological chemical degradation could possibly be a significant pathway by which these herbicides are lost from the soil.
