Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: 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.

This book was released on 1997-01-01 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmentally Sustainable Development Studies and Monographs Series No. 19. Five years have passed since the United Nations Conference on Environment and Development, better known as the Rio Earth Summit. Almost all the countries of the world attended the conference and committed themselves to the policies and programs laid out in Agenda 21, the action plan of the summit. The World Bank and other international agencies have sought to be active partners in implementing the agenda. This report is part of the Bank's current efforts to review the progress made over the past five years and to make plans for improved effectiveness for the future. The paper is divided into two parts. Part I looks at the broad picture, assessing some of the large challenges for the future and outlining thematic principles. Part II provides concise reviews of the majority of the chapters of Agenda 21 and relates them to the standpoint of Bank activities.

Download or read book Problematic Soils And Their Management written by Abhay Kumar and published by New India Publishing Agency. This book was released on 2021-10-30 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: The soils which possess characteristics that make them uneconomical for the cultivation of crops without adopting proper reclamation measures are known as problem soils. For the management of problematic soils, some general principles have to be considered for proper implementation of the reclamation measures. Some soils have serious physical and chemical limitations to cultivation. Physical limitations can be managed by irrigation, drainage, mulching, manuring, tillage, and soil conservation measures such as terracing, contouring, and cover crops, whichever is appropriate. Some chemicals are also added to the soil as an integral part of the reclamation program adopted to improve the saline, alkali and other soils. This book contains 19 chapters on Soil quality and health, Distribution of Waste land and problem soils in India and Jharkhand, Soil forming factors and Processes Reclamation and management of Saline and sodic soils, Acid soils and Acid Sulphate soils, Calcareous soils, Eroded and Compacted soils, Flooded soils, Polluted soils, Irrigation water-quality and standards, Efficient utilization of saline water in agriculture, Remote sensing and GIS in diagnosis and management of problem soils, Multipurpose tree species, Bio remediation through MPTs of soils, land capability land suitability classification, Problematic soils under different Agro-ecosystems, etc
