Hardbound. Condición: As New. New. Contents 1. Introduction. 2. Soil resource evaluation. 3. Remote sensing. 4. Soil classification. 5. Soil productivity constraints. 6. Assessment of irrigation water quality. References. The book Soil Resource Inventory and Management of Problematic Soils cover almost all the significant aspects in six different chapters. One of the primary objectives of this book is to provide comprehensive information on methods of land evaluation and problem soils. This book has been prepared based on undergraduate course of Soil Science Syllabi of Agricultural Universities of India. It covers different types and methods of soil resource inventory classification based on soil taxonomy and land evaluation methods for scientific land use planning. An attempt has been made to include remote sensing for inventorying mapping of soils and its applications in agriculture. The chapter 5 defines the characteristics of physical and chemical oriented soil problem and remedial measures to regain the quality of soil back to its original or normal productivity form. The concentration and composition of dissolved constituents in a water determine its quality for irrigation purpose. The last chapter 6 forms an important supplement to evaluate the quality of irrigation water for agriculture based on various criteria. This textbook will be useful not only to the undergraduate students but also to the Scientists of Agricultural Universities. 184 pp.…

Environmental pollution. 8. Agricultural and industrial pollution. 9. Waste management and recycling. 10. Environmental impact assessment and environmental protection. Glossary. Subject index. This book is designed to meet the needs of students who enroll for ecology and environmental science. A vast literature on this subject is available but this book is a single volume discussion covering all the aspects of ecology and environment. This book is a current and comprehensive yet not encyclopedic intended for an introductory audience. Much effort has taken to provide all possible information and the subject is discussed in multiple angles to cater the diverse interests of the reader. This book is divided into eleven chapters covering ecology ecosystem bio diversity spheres of earth environmental pollution wastes management environmental laws impact assessment environmental agencies and environmental organization. Needless to say this book would be highly useful to the under graduate and post graduate students of science subject. University faculty dealing with ecology and environmental pollution would find this book as an invaluable reference book. In fact this book is not only meant for students and teachers but also for the people who are very much concerned with the well being of our environment. The pictorial representations in this book are not just concerned with the related subject but provide extra information associated with particular subject in providing supplementary knowledge and hence increasing the knowledge by leaps and bounds. Though it is not possible to include the pictures for each and every terms associated with ecology and environment but effort has been made to include the pictures which are more relevant to the subject and will help in understanding the subject. The photos were carefully selected to add realism to the subject and to increase the interest of the reader. Since student use of the text was one of our primary concerns we made a concentrated effort to write a book that is highly usable to understand the basic and fundamental concepts of ecology and environment. To achieve this goal the book is written concisely and well illustrated. Important terms are printed in boldface type within the body of the text and a glossary is included at the end of the text for easy reference. 288 pp. …

Application of nutrients. References. Appendices. The book entitled "Nutritional Disorders in Crop Plants" has been designed to cater the needs of the under graduate and post graduate students and scientists of both agriculture and horticulture. It will also serve as both guide and ready reckoner for the extension officials of both agriculture and horticulture in understanding the principles of crop nutrition as well as in diagnosing nutritional disorders. The book will be highly useful for policy makers and planners in understanding the field problems in crops particularly nutritional disorders. This book contains 22 chapters. First 16 chapters are devoted mainly in explaining the basic concepts of plant nutrition. Four chapters are dealt with nutrient absorption and analysis. The chapter 21 is fully allotted to hunger signs of both field and horticultural crops and the last chapter 22 explains about the remedial measures. The nutrient deficiencies are very well explained and discussed. …
