Peter J. Gregory is Chief Executive of East Malling Research and a Professor at the Centre for Food Security, School of Agriculture, Policy & Development, University of Reading. He is also the author of the Wiley-Blackwell-published book, Plant Roots, and co-author of the second edition of Science and the Garden. Stephen Nortcliff is Emeritus Professor at the Soil Research Centre, Department of Geography and Environmental Science, University of Reading.

No doubt it will be bought by many libraries and should be of interest to those intending to specialise in soil science through a Masters course for example. (European Journal of Soil Science, 1 October 2013) The book is a superb foundation for in-depth class discussion. Summing Up: Highly recommended.
