Previously titled "Solute Movement in the Soil-Root System", this text describes in detail how plant nutrients and other solutes move in the soil in response to plant uptake. It provides a basis for understanding processes in the root zone so the effect of a range of variations can be predicted.

Agricultural ecology, or agroecology, deals in general with the structure and function of agroecosystems at different levels of resolution. In this text/reference, the authors describe in terms of agroecology the tropical environments of sub-Saharan Africa, Southeast Asia, and Latin and Central America, focusing on production and management systems unique to each region.

This text explains the difference between the variable charge soils of tropical and subtropical regions, and the constant charge soils of temperate regions. It focuses on the chemical properties of the variable charge soils - properties which have an important bearing on soil management practices.

As human activities in the New World Tropics (neotropics) increase in intensity and extent, so too do the interactions between natural and human-dominated ecosystems. This book of essays will treat the interaction between the sociocultural and biophysical aspects of managing the resource base in these regions.
