Plant Roots
The root system is a vital part of the plant and therefore understanding roots and their functioning is key to agricultural, plant and soil scientists. In Plant Roots Professor Peter Gregory brings together recent developments in techniques and an improved understanding of plant and soil interactions to present a comprehensive look at this important relationship, covering: Root response to, and modification of, soils Genetic control of roots’ responses to the environment Use of modern techniques in imaging, molecular biology and analytical chemistry Practical exploitation of root characters This book will be a vital tool for plant, crop, soil and agricultural scientists, plant physiologists, environmental scientists, ecologists and hydrologists. It will be a valuable addition to libraries in universities, agricultural colleges and research establishments where these subjects are studied and taught.
Soils in the Urban Environment
Urban areas contain a wide variety of open spaces, yet much of this has evolved under the pressures of human population with minimal management. The last 40 years have seen problems of varying severity begin to appear, including contamination, erosion, acidification and compaction. These problems have brought attention to the importance of the soil cover, the need for better understanding it, and the need for its protection. This book is a review of state-of-the-art science for soil in urban areas. Based on a meeting organized by the Nature Conservancy Council and the British Society of Soil Science, the nine chapters cover soil classification, contamination by waste and metals, physical and biological properties, nutrient provision and cycling, vegetation, and soil storage. The book provides a basis from which to plan future research and development programs.

Crop Traits for Defense Against Pests and Disease: Durability, Breakdown and Future Prospects, 2nd Edition
With global populations expected to exceed 9.2 billion by 2050 and available land and water resources devoted to crop production dwindling, we face significant challenges to secure global food security. Only 12 plant species feed 80% of the world’s population, with just three crop species (wheat, rice and maize) accounting for food consumed by 50% of the global population. Annual losses to crop pests and pathogens are significant, thought to be equivalent to that required to feed a billion people, at a time when crop productivity has plateaued. With pesticide applications becoming increasingly unfeasible on cost, efficacy and environmental grounds, there is growing interest in exploiting p...
Science and the Garden
"A thorough update and the introduction of new topics such as biodiversity and conservation has greatly enhanced this new edition: it is a 'must read' for all interested in horticulture and gardening." —John MacLeod, RHS Professor of Horticulture Most conventional gardening books concentrate on how and when to carry out horticultural tasks such as pruning, seed sowing and taking cuttings. This book is unique in explaining in straightforward terms some of the science that underlies these practices. It is principally a book of 'Why' – Why are plants green? Why should one cut beneath a leaf node when taking cuttings? Why do plants need so much water? But it also goes on to deal with the 'Ho...

Constitutional Law
The fifth edition of the casebook, which is suitable either for a one- or two-semester course, strives to make constitutional law easily teachable and readily accessible for students. The authors have selected the cases very carefully and provided extensive excerpts of the opinions so that students get a good sense of the Court's reasoning. Text boxes call the students' attention to important aspects of each opinion, and the book is filled with introductions, points for discussion, hypotheticals, and executive summaries. The authors present a diversity of views on every subject, and, reflecting some of their own disagreements, the authors have written point-counterpoint discussions on many disputed questions.
Gregory of Nyssa Against Eunomius
It seems that the wish to benefit all, and to lavish indiscriminately upon the first comer one’s own gifts, was not a thing altogether commendable, or even free from reproach in the eyes of the many; seeing that the gratuitous waste of many prepared drugs on the incurably-diseased produces no result worth caring about, either in the way of gain to the recipient, or reputation to the would-be benefactor. Rather such an attempt becomes in many cases the occasion of a change for the worse. The hopelessly-diseased and now dying patient receives only a speedier end from the more active medicines; the fierce unreasonable temper is only made worse by the kindness of the lavished pearls, as the Gospel tells us. I think it best, therefore, in accordance with the Divine command, for any one to separate the valuable from the worthless when either have to be given away, and to avoid the pain which a generous giver must receive from one who treads upon his pearl,’ and insults him by his utter want of feeling for its beauty.
