Environmental and agricultural modeling and assessment have a multitude of uses for soil parameters governing retention and transport of water and chemicals in soils. These parameters are notorious for the difficulties and high labor costs involved in measuring them. Good estimates instead of direct measurements may be accurate enough for many applications. Pedotransfer functions provide such estimates by utilizing available soil survey information to translate data we have into data we need. This book is the first book on the topic. It provides the unique compendium of pedotransfer functions, summarizes the vast international experience in this field, and shows how the value of soil data can be increased by using them in pedotransfer functions to predict soil hydrologic and related properties. The book is a rich source of information crucial for environmental research and applications.

"The book presents many pedotransfer results that will be useful in helping engineers, soil and environmental scientists, and researchers across a range of soil-related disciplines. This book will help readers develop a greater understanding of how to parameterize hydrological processes by using the availble information...The authors present state-of-the-art in addressing the fundamental issues of simplicity, reliability, accuracy, and utility of pedotransfer functions to predict soil hydrologic properties and processes and related phenomena...The book relates pedotransfer functions to water and solute models and gives excellent references to these models..." - M.K.
