Quantifying and Modeling Soil Structure Dynamics Quantifying and Modeling Soil Structure Dynamics emphasizes a systems approach to how soil structure changes in response to inputs and to the environment. Soil structure is a dynamic complex system affected by tillage wheel traffic roots soil life shrink swell and freeze thaw. In turn soil structure affects root growth and function soil fauna solute transport water infiltration gas exchange thermal and electrical conductivities traffic bearing capacity and more. Ignoring soil structure or viewing it as static can lead to poor predictions and management. Readers will especially appreciate the description of soil structure influence on endpoints such as environmental contamination and efficient water use and how models should be adjusted to include dynamic soil structure components for accurate outputs page 4 of cover
