This book is intended for students and soil scientists who want to know about the state of the art in soil sciences in Chile. The book merges a comprehensive bibliographical review of the soil surveys carried out throughout the length and breadth of Chilean territory during the past 40 years and more recent information obtained by the authors in a number of field studies. As its starting point the book presents a general overview of important features related to Chilean soils, such as geology and geomorphology, climate, land use and vegetation. In this long and narrow country different soil formation factors and processes have resulted in a broad variety of soil bodies, from the extremely arid Atacama desert to the Patagonian and Antarctic zones. This book provides a description and classification (mainly Soil Taxonomy) of the most important soil types. Particularly important are soils derived from volcanic materials, which cover extensive areas of Chile. The book also deals with soil management topics in relation to the chemical, physical and biological properties of Chilean soils and it includes a number of examples from throughout the country. Finally, the book shows how man has induced severe soil degradation problems in Chile, such as erosive soil degradation, non-erosive soil degradation and land desertification.

Plants depend on physiological mechanisms to combat adverse environmental conditions, such as pathogen attack, wounding, drought, cold, freezing, salt, UV, intense light, heavy metals and SO2. Many of these cause excess production of active oxygen species in plant cells. Plants have evolved complex defense systems against such oxidative stress. The

Volcanic eruptions are generally viewed as agents of destruction, yet they provide the parent materials from which some of the most productive soils in the world are formed. The high productivity results from a combination of unique physical, chemical and mineralogical properties. The importance and uniqueness of volcanic ash soils are exemplified by the recent establishment of the Andisol soil order in Soil Taxonomy. This book provides the first comprehensive synthesis of all aspects of volcanic ash soils in a single volume. It contains in-depth coverage of important topics including terminology, morphology, genesis, classification, mineralogy, chemistry, physical properties, productivity and utilization. A wealth of data (37 tables, 81 figures, and Appendix) mainly from the Tohoku University Andisol Data Base is used to illustrate major concepts. Twelve color plates provide a valuable visual-aid and complement the text description of the world-wide distribution for volcanic ash soils. This volume will serve as a valuable reference for soil scientists, plant scientists, ecologists and geochemists interested in biogeochemical processes occurring in soils derived form volcanic ejecta.

The purpose of this report is to review and summarise published research on the efficiency and management of riparian buffer zones (RBZ) with respect to the attenuation of sediment and nutrients, and biodiversity enhancement. While there have been numerous studies on the efficiency of RBZ with respect to sediment and nutrients, many of these studies have been small-scale and site-specific. Therefore, a review of these studies needs to consider an assessment of the catchment scale factors that influence the effectiveness of RBZ in attenuating catchment loads.

'Without vision the people perish.' So wrote the poet William Blake. Lord Northbourne (1896-1982) was a man of exceptional and comprehensive vision, who diagnosed the sickness of modern society as stemming from the severance of its organic links with the wholeness of life. But like his better-known younger contemporary E. F. Schumacher (author of Small is Beautiful), whose work developed along very similar lines, Northbourne's occupation as a practicing organic farmer (he coined the term) was joined to a deep conviction that humanity does not live by bread alone, and that the fullness of life properly integral to human nature demands obedience to sacred law. Thus his vision of life came to embrace the interrelationship of God, humanity, and the soil as a unity presupposing a way of life in stark contrast to that of the myopic, mechanististic world he saw encroaching on all sides. And so, as it becomes increasingly evident that such a way of life stands to emperil our very future and that of the delicate ecosystem on which all life depends, it is time to re-examine the work of this pioneering thinker. In an age of specialization and fragmentation, we have much to learn from Northbourne, whose vision of what is required by a truly meaningful and sustainable society embraced religion, farming, the arts, the rural crafts, monetary form, and traditional metaphysics. Northbourne's later works, Religion in the Modern World and Looking Back on Progress, present his wider reflections on the Divine and human society, but always with the sensibility of a man who knows the soil, recalling in many ways the writings of Wendell Berry. He corresponded with Thomas Merton, as well as mountaineer and Tibetan Buddhist Marco Pallis (The Way and the Mountain), who introduced him to the school of perennialist writers. Northbourne translated René Guénon's The Reign of Quantity and the Signs of the Times, described by Huston Smith as one of the truly seminal books of the twentieth century, as well as Frithjof Schuon's Light on Ancient Worlds and Titus Burckhardt's Sacred Art in East and West. He was also an accomplished flower gardener and watercolorist, and a frequent contributor to the British periodical Studies in Comparative Religion, described by Schumacher as one of the two most important journals to read. Sophia Perennis is republishing all three of Northbourne's works, a fourth volume of uncollected essays spanning agriculture and metaphysics, as well as the 23-volume Collected Writings of René Guénon, including The Reign of Quantity. Lord Northbourne (1896-1982) was a man of exceptional vision, who already in the 1940s diagnosed in detail the sickness of modern society as stemming from the severance of its organic links with the wholeness of life. A leading figure in the early organic farming movement, his writings profoundly affected such other pioneers as Sir Albert Howard, Rolf Gardiner, Ehrenfried Pfeiffer, and H. J. Massingham. His path led him on to a profound study of comparative religion, traditional metaphysics, and the science of symbols, which he employed in incisive observations on the character of modern society. His later writings exercised considerable influence on his younger contemporaries E. F. Schumacher and Thomas Merton, and in many ways anticipate the essays of Wendell Berry. The republication of this milestone ecological text will be followed by three volumes of Northbourne's later metaphysical and cultural writings. "A major text in the organic canon, too long out-of-print" - Philip Conford, The Origins of the Organic Movement "We have tried to conquer nature by force and by intellect. It now remains for us to try the way of love." - From the book (possibly for front cover, if not too long?)

Forests and woodlands provide an enormous range of goods and services to society, from timber and firewood to medicinal plants, watershed protection, destinations for tourists and sacred sites. Only when these are understood and valued can forests and their resources be properly managed and conserved. This work shows how the complicated network of benefits can be untangled and sets out the different approaches needed to value them. It covers the analysis of plant-based markets, non-market valuation and decision frameworks such as cost-benefit analysis.

In this book, agronomist Ricardo Ayerza and agricultural engineer Wayne Coates trace the long and fascinating history of chia's use, then reveal the scientific story of the plant and its modern potential. They compare fatty acid profiles of chia with our other major sources--fish oil, flaxseed, and marine algae--and provide evidence that chia is superior in many ways. Here are just some of the benefits that chia provides: - chia has the highest known percentage of alpha-linolenic acid, and the highest combined alpha-linolenic and linoleic fatty acid percentage of all crops- chia has more protein, lipids, energy, and fiber--but fewer carbs--than rice, barley, oats, wheat, or corn--and its protein is gluten-free- chia is an excellent source of calcium, phosphorus, magnesium, potassium, iron, zinc, and copper- chia is low in sodium: salmon has 78 times as much, tuna 237 times as much- chia exhibits no evidence of allergic response, even in individuals with peanut and treenut allergies- chia doesn't give off a "fishy flavor," unlike some other sources of omega-3 fatty acid- superior to other plant and marine sources of omega-3- low in sodium- high in protein, lipids, and fiber- fewer carbs than most other grains- valued as an energy source for athletic endurance.
