The application of fractals and fractal geometry in soil science has become increasingly important over the last few years. This self-contained and timely book was designed to provide detailed and comprehensive information on the current status of the application of fractal geometry in soil science, and on prospects for its future use. With a detailed and specific introductory chapter, particular attention is paid to comparing and contrasting "fractal" and "fragmentation" concepts. Some uses of fractals, such as to quantify the retention and transport properties of soils, to describe the intricate geometry of pore surfaces and macropore networks, or to elucidate the rooting patterns of various plants, are discussed. Applications of fractals in soil science are both relatively recent and in constant evolution. This book reflects accurately existing trends, by allowing sharp differences among the viewpoints expressed in contributed chapters to be presented to the reader in one self-contained volume.

In a parallel life, when he is not actively leading the team at SIMBIOS, Professor Baveye also is the Kodak Professor of Environmental Engineering at the Rensselaer Polytechnic Institute in Troy, New York. His research program there revolves around the bioclogging of soils and membranes, and is intimately connected with the work done at Abertay.
Jean-Yves Parlange was awarded the Horton Medal at the AGU Fall Meeting Honors Ceremony, which was held on 10 December 2003, in San Francisco, California. The medal honors "outstanding contributions to hydrology."
Bobby A. Stewert Ph.D., is distinguished professor of Soil Science at West Texas A&M University, Canyon Texas.
