Soils are neither good nor bad, but some have inherent or acquired characteristics that may or may not suit our intended use. Unsuitable characteristics are considered to be soil problems, soil constraints or soil limitations. Only twelve percent of global land is right for agricultural production without much limitation. Some soils have severe limitations for crop production. These soils are so called ‘problem soils’. Many of them do not have enough fertility to be productive; some are arid and saline; some are very sandy and dry; and some are wet and waterlogged for most of the growing season. The global demand for food, wood, fuel, fiber, medicine and other plant products for the 7.2 billion current world population has created such an immense pressure on global soil resources that even the most fertile soils are losing their productive capacity. We are being compelled to bring more and more unsuitable or marginally suitable soils under cultivation. Unless innovative and integrated soil, crop and environmental management practices are adopted for their improvement and sustainable use, further degradation is inevitable. This book, Management of Soil Problems, identifies the problems and discusses management options in a smooth and reader-friendly style. It will be useful for students and professionals of soil science, agriculture, forestry, geography and environmental sciences.

The soil is a fundamental constituent of the Earth's system, maintaining a careful state of equilibrium within the biosphere. However, this natural balance is being increasingly disturbed by a variety of anthropogenic and natural processes, leading to the degradation of many soil environments. Soil Management provides a comprehensive and authoritative introduction to the many problems, challenges and potential solutions facing soil management in the twenty-first century. Covering a range of topics, including erosion, desertification, salinization, soil structure, carbon sequestration, acidification and chemical pollution, the book also develops a prognosis for the future of soil management in the face of growing populations and global warming. Written with the needs of students in mind, each chapter provides a broad overview of a problem, analyses approaches to its solution and concludes with references and suggestions for further reading. Soil Management will be of great value to environmental science and geography undergraduates taking soil management courses in their second or third year.

Document from the year 2011 in the subject Agrarian Studies, University of Greenwich, language: English, abstract: It is widely recognised that environmental problems such as soil degradation (erosion and desertification) affects many agricultural lands globally. These problems have caused soil quality decline, crop yield reduction, economic crisis, poverty, unemployment, and rural urban migration. Soil management practices are considered as the most vital and sustainable possible solution to control soil erosion and desertification. This management include use of organic manure, crop rotation, use of cover crop, intercropping, planting shelter belt and afforestation, provision of water ways, good surface drainage system, restoration of rangeland, regeneration and secondary forest, and political changes.

This is a unique book that deals with the problem soils, their constraints and management in the Indian context. The book starts with the introduction on problem soils and the classification of these soils are included there under. In India, there is wide spread occurrence of soils with different types of constraints for crop production. Such soils are popularly called as “Problem Soils”. Cultivation in these soils is not so easy as several problems have to be tackled during cultivation. It may be either soil droughtiness or acidity or salinity etc. An attempt has been made in this book to cover most of the problematic soils in India. The classification of problem soils has been done based on the limitations they possess and the most dominant limitation is taken into consideration for grouping it under a particular class. Here five broader classes have been identified viz., soils with climatic problems; soils with physical problems; soils with chemical problems; soils with biological problems and soils with problems due to anthropogenic reasons. Note: Taylor and Francis does not sell or distribute the print editions of this title in India, Pakistan, Nepal, Bhutan, Bangladesh and Sri Lanka.

Management of Problem Soils in Arid Ecosystems examines the challenges of managing soils in arid and semiarid regions. These soils contain low organic matter, are not leached, and accumulate lime, gypsum, and/or soluble salts, requiring special management and practices. This book discusses how to identify problems, reclaim the soils, and then use them efficiently and economically. Water management and desertification in these areas are also discussed. It contains extensive references as well as 40 tables and illustrations.

Despite almost a century of research and extension efforts, soil erosion by water, wind and tillage continues to be the greatest threat to soil health and soil ecosystem services in many regions of the world. Our understanding of the physical processes of erosion and the controls on those processes has been firmly established. Nevertheless, some elements remain controversial. It is often these controversial questions that hamper efforts to implement sound erosion control measures in many areas of the world. This book, released in the framework of the Global Symposium on Soil Erosion (15-17 May 2019) reviews the state-of-the-art information related to all topics related to soil erosion.

“Principles of Soil Management and Conservation” comprehensively reviews the state-of-knowledge on soil erosion and management. It discusses in detail soil conservation topics in relation to soil productivity, environment quality, and agronomic production. It addresses the implications of soil erosion with emphasis on global hotspots and synthesizes available from developed and developing countries. It also critically reviews information on no-till management, organic farming, crop residue management for industrial uses, conservation buffers (e.g., grass buffers, agroforestry systems), and the problem of hypoxia in the Gulf of Mexico and in other regions. This book uniquely addresses the global issues including carbon sequestration, net emissions of CO2, and erosion as a sink or source of C under different scenarios of soil management. It also deliberates the implications of the projected global warming on soil erosion and vice versa. The concern about global food security in relation to soil erosion and strategies for confronting the remaining problems in soil management and conservation are specifically addressed. This volume is suitable for both undergraduate and graduate students interested in understanding the principles of soil conservation and management. The book is also useful for practitioners, extension agents, soil conservationists, and policymakers as an important reference material.

Master's Thesis from the year 2007 in the subject Agrarian Studies, grade: Merit class, Natural Resources Institute - University of Greenwich at Medway (-), course: Plant Health and Protection, language: English, abstract: Although it is widely recognised that environmental problems such as soil degradation erosion and desertification threaten sustained agricultural production in many States of northern Nigeria including Adamawa, Bauchi, Borno, Gombe, Jigawa, Kaduna Kano, Katsina, Kebbi, Sokoto and Zamfara. Very little information is available about the current status of the potential impact of soil degradation and whether the situation is worsening in all the States of northern Nigeria. However, it is now clear that the major factor explaining the severity and spatial distribution of soil degradation such as erosion and desertification in northern Nigeria is associated with human impact such as deforestation and mismanagement of land resources. Other factors includes overgrazing, use of mechanized equipment, deforestation and lack of government concern to protect the environment in the region, but few studies have been made on applied issues related to the physical and chemical processes including erosion, runoff and leaching. These problems are widely considered as a serious problem to agricultural production and its environmental consequences will remain an important issue during the 21st century. Possible solutions such as soil management practices will help to minimise/control soil degradations which caused serious hazards to farmer's land in northern Nigeria. Sustainable soil management practices are vital for enhancing and sustaining the productivity of soil, food, livestock, water quality and other related land resources such as forestry in northern Nigeria. It is more efficient in terms of reduced environmental impact, high risk of soil degradation and soil erosion. These management practices are: (a) applying organic manure regularly, (b) growing cover c

This publication reviews issues related to land degradation, with focus on problems of soil fertility management in sub-Saharan Africa. It highlights some successful experiences in the region, constraints and possible solutions specific to the major agro-ecological zones and the importance of the holistic and participatory approaches for soil productivity improvement. The need for action and collaborative efforts of all stakeholders, within the framework of ongoing initiatives, are emphasized. It is hoped that this document will contribute to increase awareness of senior specialists and policy-makers about the problems and alternative solutions towards enhanced and sustained soil productivity.
