The adsorption and degradation of two herbicides, 2,4,dichlorophenoxyacetic acid (2,4‐D) and 2,4,5‐trichlorophenoxyacetic acid (2,4,5‐T), were examined in three soils either freshly amended or preconditioned for 2 months with sewage sludge. Sludge additions generally enhanced herbicide degradation, but had no effect on 2,4‐D degradation in a soil with a history of 2,4‐D applications. Fresh sludge additions had little effect on herbicide adsorption by soils, while preconditioning the sludge‐soil mixtures generally increased herbicide adsorption.
