Topically applied chemical, fate

Kinetics of reactions in soil and aquatic environments is a topic that is of extreme importance and interest. Most of the chemical processes that occur in these systems are dynamic, and a knowledge of the mechanisms and kinetics of these reactions is fundamental. Moreover, to properly understand the fate of applied fertilizers, pesticides, and organic pollutants in soils with time, and to thus improve nutrient availability and the quality of our groundwater, one must study kinetics.
