Tillage for Sustainable Cropping is a state of the art examination of diverse tillage systems and tillage induced edaphic changes and their implications for soil productivity and the environment. It provides a rational framework for tillage systems that takes soil and climatic characteristics and the availability of other edaphic inputs into consideration. This well referenced volume also examines soil sustainability in terms of pollution greenhouse gases water contamination growing production demands and soil degradation and looks at the way crops respond to tillage techniques in terms of weed growth root growth crop yields and more. 195 pp.

Democracy and Press has it and it seems like many other countries want it. Despite the banter in today's media many Indians are still in the dark when it comes to knowing and acting upon their rights and responsibilities as citizens of a democratic society. In refreshingly candid and straight to the point language editor takes readers of all ages on an A Z trip through our government's structure from its earliest beginnings to definitions of basic components and concepts. This volume in the series takes a close look at the role of the press in a democracy through a collection of essays by journalists and scholars. The essays examine the orientation of the press in a democracy the function of the press in democracies the government and the press the structure and nature of the Indian Press and the future of news and journalism. The collection is aimed at correcting mistaken impressions about Indian media that mainstream conventional journalism is the only legitimate journalism that journalism as practiced currently in the India is the only valid model and that Indian journalism is not affected by journalistic trends and developments in other nations. The text offers a great deal of information about the history of democracy the development and processes of Indian Government and the people who have contributed to our country. 260 pp.

Hardbound. Zustand: Reprint. Contents: Preface. Introduction. 1. Intensive cropping and related concerns. 2. Efficient input use: terminology and requisites. 3. Toward efficient water use. 4. Toward efficient nutrient use. 5. Toward efficient use of energy in tillage. 6. Toward sustainability of high-production systems. 7. Modeling for efficient input use. References. Index. " Intensive Cropping combines the basic and applied aspects of soil water, nutrients, and energy management to help you optimize your crop yields and maximize the use of these inputs in intensively farmed regions. In Intensive Cropping, you will explore the need for extreme farming and related concerns and concepts, including: vCreating methods to conserve water by reducing runoff deep seepage, and evaporation losses v Supplementing irrigation with surface and groundwater vUnderstanding the process of water uptake and the effects on root dynamics and water use v Reducing gaseous, leaching, and erosion losses in your fields vUsing combinations of organic manures, crop residues, chemical fertilizers, and biofertilizers for soil maintenance vImplementing conventional and emerging tillage systems, such as conservation tillage for improving soil quality vExamining case studies of contrasting edaphic requirements of rice-wheat systems."
