These lecture notes describe the major soils of the world and their properties, genetic formation, regional distribution, their management and associated land use. The World Reference Base for Soil Resources (WRB) is used throughout the text, as the basis for a universal classification system for soil correlation. The aim of the publication is to make the WRB accessible to young scientists. It is intended to facilitate the study of soils and the exchange of soil information, and provides a common language for soil science.
This publication is a revised and updated version of World Soil Resources Reports No. 84 and 103 and presents the international soil classification system. Every soil in the world can be allocated to one of the 32 Reference Soil Groups as defined in this document, and can further be characterized by a set of qualifiers. The resulting soil name provides information on soil genesis, soil ecological function and soil properties relevant for land use and management. The same system, refined slightly, may be used to name the units of soil map legends, thereby providing comprehensive spatial information. By accommodating national soil classification systems, the World Reference Base facilitates the worldwide correlation of soil information.
This book publishes consolidated information on the soils of Nepal from all possible sources. The Survey Department, Government of Nepal, conducted two national scale soil survey projects to classify soils of Nepal (Land Resource Mapping Project ended in 1985, and National Land Use Planning Project ended in 2021). Both projects adopted the United States Department of Agriculture system of soil classification. Besides, National Soil Science Research Center (previously known as Soil Science Division) of Nepal Agricultural Research Council and Soil Management Directorate, Department of Agriculture, also worked on soils of Nepal. To date, the information on the soils of Nepal is not published in well-documented form but has been reported widely as gray literature (project report or government report) or peer-review articles. 'The Soils of Nepal’ is a part of ‘World Soils Book Series’ which constitutes twelve chapters—covering broad aspects such as soil research history, climate, geology, soil classification and mapping, and soil fertility. Furthermore, information about soil properties and relation between soil constituents of the dominant soil types of Nepal and their scope of use in the context of land use are described. This book also tries to simplify the intricate relationship among soil, culture, and people. Each chapter contains a comprehensive, richly illustrated, and up-to-date overview of the soils of Nepal. We believe it fulfils a quest for a global audience including students, educators, extension workers, and soil scientists, who are interested to know the young soils of Nepal.
A celebrated biologist's manifesto addressing a soil loss crisis accelerated by poor conservation practices and climate change "Jo Handelsman is a national treasure, and her clarion call warning of a looming soil-loss catastrophe must be heard. Add her clearly written alarm to other future-shocks: climate change, pandemics, and mass extinctions."--Laurie Garrett, Pulitzer Prize winner and author of The Coming Plague: Newly Emerging Diseases in a World out of Balance "The ground beneath our feet is slipping away as we lose the precious soil that sustains us. Jo Handelsman's writing--as rich and life supporting as the soil itself--is a riveting warning."--Alan Alda, actor, writer, and host of the podcast Clear+Vivid with Alan Alda This book by celebrated biologist Jo Handelsman lays bare the complex connections among climate change, soil erosion, food and water security, and drug discovery. Humans depend on soil for 95 percent of global food production, yet let it erode at unsustainable rates. In the United States, China, and India, vast tracts of farmland will be barren of topsoil within this century. The combination of intensifying erosion caused by climate change and the increasing food needs of a growing world population is creating a desperate need for solutions to this crisis. Writing for a nonspecialist audience, Jo Handelsman celebrates the capacities of soil and explores the soil-related challenges of the near future. She begins by telling soil's origin story, explains how it erodes and the subsequent repercussions worldwide, and offers solutions. She considers lessons learned from indigenous people who have sustainably farmed the same land for thousands of years, practices developed for large-scale agriculture, and proposals using technology and policy initiatives.
Long-awaited second edition of classic textbook, brought completely up to date, for courses on tropical soils, and reference for scientists and professionals.
This book provides an overview of the distribution, properties, and function of soils in Japan. First, it offers general descriptions of the country’s climate, geology, geomorphology, and land use, the history of the Japanese soil classification system and characteristics and genesis of major soil types follow. For each region – a geographic/administrative region of the country – there is a chapter with details of current land use as well as properties and management challenges of major soils. Maps of soil distribution, pedon descriptions, profile images, and tables of properties are included throughout the text and appendices.
This book presents a comprehensive and up-to-date overview on soils of Greece. It includes sections on soil research history, climate, geology, geomorphology, major soil types, soil maps, soil properties, soil classification, soil fertility, land use and vegetation, soil management, soils and humans, soils and industry, future soil issues. The book summarizes what is known about the soils in Greece in a concise and highly reader-friendly way.
Audience: Students studying environmental science or participating in an Envirothon or Science Olympiad will find Know Soil, Know Life is an easily accessible resource. Undergraduate students in introductory ecology and environmental science classes will have a manageable soils textbook. Scientists in related disciplines wildlife, forestry, geology, hydrology, biology, zoology will enjoy this engaging introduction to soils.
An illustrated overview of the sustainability of natural resources and the social and environmental issues surrounding their distribution and demand.
This is the first comprehensive book on Argentinian pedology. It discusses the main soil types of Argentina, their geographical distribution, classification, functions, agricultural use, ecological aspects, and the threats to which they have been subjected during centuries of intensive and extensive management. The description of the soils is accompanied by a complete set of data, pictures and maps, including benchmark profiles and an overview of the country's agricultural production. It also deals with future scenarios of the relationships between soil science and other disciplines and the main challenges that soil science will face in the future. Further, the book explores aspects of the main soil forming factors, such as climate, vegetation, geology and geomorphology, making use of new, unpublished data and elaborations, and presents a history of pedological research in Argentina.
