Book Description
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.

Book Description
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.

Book Description
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.

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

Book Description
How can the United States meet demands for agricultural production while solving the broader range of environmental problems attributed to farming practices? National policymakers who try to answer this question confront difficult trade-offs. This book offers four specific strategies that can serve as the basis for a national policy to protect soil and water quality while maintaining U.S. agricultural productivity and competitiveness. Timely and comprehensive, the volume has important implications for the Clean Air Act and the 1995 farm bill. Advocating a systems approach, the committee recommends specific farm practices and new approaches to prevention of soil degradation and water pollution for environmental agencies. The volume details methods of evaluating soil management systems and offers a wealth of information on improved management of nitrogen, phosphorus, manure, pesticides, sediments, salt, and trace elements. Landscape analysis of nonpoint source pollution is also detailed. Drawing together research findings, survey results, and case examples, the volume will be of interest to federal, state, and local policymakers; state and local environmental and agricultural officials and other environmental and agricultural specialists; scientists involved in soil and water issues; researchers; and agricultural producers.

Book Description
The main objective of this book is to integrate environmental knowledge observed in local agriculture, based on the understanding of soils science and ecology, and to propose possible technical solutions and a more integrated approach to tropical agriculture. The chapters describe and analyze the ecological and technical countermeasures available for mitigating environmental degradation due to the increasing agricultural activities by humans, based on our scientific understanding of traditional agriculture in the tropics. This is an effective approach, as such ecological and technical tools previously involved in traditional activities are expected to be easily incorporated into present agricultural systems. The book starts with a rather classical pedological issue and analyzed traditional agricultural practices with different resource management strategies in terms of their modification of natural biological processes. It focuses on the present situation of tropical agriculture; that is, resource utilization in modern agriculture after application of technical innovation (increased application of chemical fertilizers as well as agricultural chemicals). Here, possible technical approaches to resource management that reasonably support agricultural production whilst mitigating environmental degradation are discussed. The negative impacts of agricultural development on our environment are rapidly growing, yet we are increasingly dependent on the agricultural sector for food and energy. The situation is similar in the tropics, where subsistence agriculture with low input management has long comprised most agricultural systems. Comparison of ecological and/or agronomical studies between different continents are still rare; therefore, this analysis may help clarify what is an essential problem when considering technical transportation beyond continents and/or between temperate and tropical regions.
