Recent changes in the Conservation Compliance Plans for farmers shows the need for improved information on the effective management of crop residues. Residue management requires an understanding of the crop, soil, and climate in which the farming system is located. In this volume, the strategies for effective residue management are described for each region of the country to provide a comparison of the regional differences. The chapters not only describe the knowledge in each region but also suggest some of the needed areas of research required to develop an improved understanding of the processes involved in effective residue management.

Soil Biology is a state-of-the art review focusing on the linkage between biological processes that occur in the soil and their impact on soil quality. Topics considered include the microbial ecology of conservation management systems, dynamic processes of vesicular-arbuscular mycorrhizae, earthworms and soil fauna, microbial processes in the soil, and the degradation of pesticides through microbial processes. The book will interest soil scientists, microbiologists, agronomists, and soil ecologists.
