Edible ectomycorrhizal mushrooms (EEMMs) comprise more than 1000 species and are an important food and forest resource. In this volume of Soil Biology, internationally recognized scientists offer their most recent research findings on these beguiling fungi. Topics covered include: complex ecological interactions between plants, EEMMs, and soil organisms; comparative genomics, high-throughput sequencing and modern research tools; genetic selection of fungal strains and techniques for inoculating plants; economic and social considerations surrounding wild collected EEMMs; and practical information concerning soil management and EEMM cultivation. The book will be a useful guide for anyone interested in soil ecology, forestry, or the genetics and cultivation of EEMMs, and provides an extensive knowledge base and inspirations for future studies on these ecologically and economically important fungi.

After giving a brief history of tillage practices and implements used throughout the world dating back to ancient times, this book goes on to describe the basic soil mechanics techniques needed to calculate the forces developed in soil by simple-shaped cutting tools. The methods of measuring soil mechanical properties, water pressure in soil and shear rate effects are touched upon. A review is given of two and three dimensional soil cutting mathematical mechanics models to predict soil cutting forces and soil volumes disturbed by cutting and tillage tools, as well as the state-of-the-art of soil loosening, structural rearrangement and plant growth as affected by tillage tools. The author also includes an introduction to the analysis of traction machines. There are many numerical examples of mechanical analyses and predictions worked out in the various sections of the book as well as numerous unsolved problems at the end of a number of the chapters. Written in a textbook style, this monograph is ideal for anyone wanting to learn modern techniques for the mechanical description of soil cutting and tillage forces and soil volumes disturbed.

This popular book incorporates modern approaches to physics. It not only tells readers how physics works, it shows them. Applications have been enhanced to form a bridge between concepts and reasoning.
