Interpretive Summary:

Technical Abstract: Conservation management systems such as those that include reduced tillage or cover crops are gaining popularity because of environmental concerns and the need to reduce production costs. These practices result in an increased accumulation of plant residues on the soil surface, which have important implications for the deposition / interception and fate of applied chemicals such as herbicides. Changes in soil characteristics such as increased microbiological activity, sorption capacity, and preferential channeling through soil profiles, have an influence on the dissipation of herbicides, and these factors are discussed in this review.
