Introduction

An understanding of water movement and chemical properties is necessary for understanding how agricultural chemicals (nutrients and pesticides) move from the field surface to streams and ground water. Effective conservation practices should account for the interdependent influences between water movement and chemical properties to reduce agricultural-chemical transport to streams and ground water. Environmental managers need to understand that conservation practices designed to control agricultural-chemical transport along one pathway, for example in runoff, may have an undesirable effect in controlling transport along another pathway, for example through soils.
