Book Description
This book describes the outstanding features of the ecology and bio geography of the Indian region, comprising former British India, Nepal, Bhutan, Ceylon and Burma. It summarizes the results of nearly four decades' studies and field explorations and discussions with students on the distribution of plants and animals, practically throughout this vast area and on the underlying factors. A number of specialists in geology, meteorology, botany, zoology, ecology and anthropology have also actively collaborated with me and have contributed valuable chapters in their respective fields. India has an exceptionally rich and highly diversified flora and fauna, exhibiting complex composition, character and affinities. Although the fauna of the Indian region as a whole is less completely known than its flora, we are nevertheless fairly well acquainted with at least the salient features of its faunal characters to enable us to present a meaningful discussion on some of the outstanding peculiarities of the biogeography of India. A general synthesis of the available, though much scattered, information should prove useful to future students of biogeography throughout the world.

Book Description
The red soils of China are typical in their chemical, physical and mineralogical characteristics of red soils in other tropical and sub-tropical areas of the world, particularly in South America, Africa and south-east Asia. For the most part, these soils are highly weathered and inherently infertile. They are acidic, nutrient deficient, poor in organic matter and have a low water-holding and supplying capacity. They cannot sustain arable cropping systems without the most careful management and are highly susceptible to soil erosion, particularly on sloping land. It is the purpose of this book to present recent research showing how the problems associated with using the red soils in China for sustainable agricultural production can be overcome, using a variety of traditional and novel approaches. In principle, these approaches should be useful in other tropical and sub-tropical countries faced with the problem of making the best use of their fragile red soil resources. The term "in principle" is used deliberately because, of course, the different red soil countries invariably operate within dissimilar socio-economic frameworks. At the present time, China may be considered to be in the process of an "industrial revolution", rather like that that took place in Britain in the late eighteenth and early nineteenth centuries.

Book Description
This Book Brings Out The Possibilities Of Generalizations Of Behaviour Of Soils And Hence Of Predicting The Required Engineering Properties Without Elaborate Testing. We Recognize That A Single Approach Cannot Be Evolved For All Soil Types And Hence The Necessity For Classifying Soils Into Different Categories And To Use Appropriate Model For Each. First Of All, Based On Mechanism Of Stress Transfer And Interaction Between The Phases, Two Obvious Classes, The Fine Grained And Coarse-Grained Soils Have Been Differentiated.The Discussions Bring Out That Because Of Identical Mode Of Stress Transfer, The Mechanical Behaviour I.E., Compressibility, Shear Strength Relations, Permeability Variations Etc. Can Be Generalized For All Fine Grained Soils, Enabling The Prediction Of Behaviour Of Such Soils With Just The Knowledge Of Certain State And Index Properties. The Sequence Of Discussion Is On The Characterization Of Specific Soil States And Prediction Of Proportion Starting From The Ideal Saturated Uncemented Soils, Both Normally And Over Consolidated, Cemented Saturated Soils And Partly Saturated Soils.In Dealing With The Behaviour Of Coarse Grained Soils, The Importance Of Microfabric And The Difficulties In Possible Generalizations Are Discussed. Perhaps The Unique Feature Of This Book Is That The Division Of The Chapters Is Based On Different Soil States, All The Mechanical Behaviours Being Discussed Under Each Soil State.The Book Will Be Of Interest To Both Academicians And Practising Engineers, Researchers And Postgraduate Students. It Would Serve As A Textbook For Undergraduate Students With Prior Knowledge Of Basic Soil Mechanics.

Book Description
Applied Geographers have the knowledge, tools and skills to help resolve these conflicts and play an essential part within a multi-cultural world in which understanding, tolerance and sensitivity are fundamental to social and economic well-being and to the good management of our natural environment. Geography was always applied, long before it became an identified academic discipline; much geographical knowledge was created for specific purposes. Since the discipline was established, individuals have used their knowledge in a wide range of contexts and for various types of clients. For the first half of the 20th century, the development of geography as an academic discipline was closely associated with its educational role, especially in the preparation of teachers and of teaching materials. Increasingly, however, geographers responded to societal changes—especially the extending role of the state—by promoting their discipline as a potential contributor in a range of activities. Some, like L. Dudley Stamp, argued that geographers’ factual knowledge regarding environments and places plus their understanding of spatial organization principles should be applied in town, city, country, and regional planning. This could just involve information provision, but increasingly it was argued that geographical analyses could inform the understanding of current patterns and trends and the preparation of plans for the future. Such geographical involvement expanded in the late 20th century as pressures grew on universities to orient their work more to societal needs and to undertake applied research for public- and private-sector sponsors. A useful book for those who are interested in the study of this subject. It may equally be liked by the general readers interested in studying the topic as also the academics, public administrators and practitioners. Contents: • Population Geography • Economic Geography • Political Geography • Regional Planning • Geography of India

Book Description
This book catalogues the multi-scale impact of agronomy and economy on Cardamom, known as the “Queen” of spices. Cardamom is the second most important spice crop in the world, after Black pepper, known as the “King” of spices. Spices were the symbols of luxury and royalty, and cardamom was used in the manufacture of perfumes during the Greek and Roman times. It became one of the most important Oriental spices used in both Greek and Roman cuisine as well as its pharmacological applications. The book is divided into 15 chapters and concentrates on aspects of cardamom production and processing, the taxonomic aspects of cardamom, chemistry, pathology, entomology and is concluded with the future of cardamom. Special emphasis is given to the utility of “The Nutrient Buffer Power Concept”, a soil management technique in precise fertilizer management, especially with regard to Potassic fertilizers in cardamom production.

Book Description
This book discusses how research efforts have established an organic link between pedology and edaphology of five pedogenetically important soil orders as Alfisols, Mollisols, Ultisols, Vertisols and Inceptisols of tropical Indian environments. The book highlights how this new knowledge was gained when research efforts were complemented by high resolution mineralogical, micro morphological and age-control tools. This advancement in basic and fundamental knowledge on Indian tropical soils makes it possible to develop several index soil properties as simple methods to study their pedology and edaphology. More than one-third of the world’s soils are tropical soils. Thus the recent advances in developing simple and ingenuous methods to study pedology and edaphology of Indian tropical soils may also be adopted by both graduate students and young soil researchers to aid in the development of a national soil information system to enhance crop productivity and maintain soil health in the 21st century.
