Reviewing Mathematical Models for Pesticide Leaching Studies

Leaching is an unavoidable phenomenon associated with the pesticide applications. Leaching of pesticide does not only indicate the efficiency of a pesticide molecule, but also degree of the environmental contamination. Leaching is the process by which a pesticide molecule enters the soil-water ecosystem. Hence, to access the leaching behavior of a pesticide molecule, various models are used globally. This paper reviewed some globally adapted leaching models and tried to find the best fitted model for leaching study.
