Available in PDF, EPUB and Kindle. Book excerpt: We are entering a new era in production agronomics. Agricultural scientists the world over call for the development of techniques that simultaneously increase soil carbon storage and reduce agriculture's energy use. In response, site-specific or precision agriculture has become the focus and direction for the three motivating forces that are changi

Download or read book Push Button Agriculture written by K. R. Krishna and published by CRC Press. This book was released on 2017-03-16 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers three main types of agricultural systems: the use of robotics, drones (unmanned aerial vehicles), and satellite-guided precision farming methods. Some of these are well refined and are currently in use, while others are in need of refinement and are yet to become popular. The book provides a valuable source of information on this developing field for those involved with agriculture and farming and agricultural engineering. The book is also applicable as a textbook for students and a reference for faculty.

Download or read book Optimizing Nitrogen Management in Food and Energy Production and Environmental Protection written by J. Galloway and published by CRC Press. This book was released on 2002-01-01 with total page 1042 pages. Available in PDF, EPUB and Kindle. Book excerpt: The production of food and energy interfere with the natural nitrogen cycle of the earth. Many of these changes are beneficial, while others are detrimental to societies and the environment. The changing nature of nitrogen in the global environment crosses scientific disciplines, geographical boundaries and political divisions and challenges the creative minds of natural and social scientists, economists, engineers, business leaders and planners. The papers in this book give readers a panoramic view of the changing nature of reactive nitrogen in the global environment, enabling them to make better choices about nitrogen management in food production and consumption, energy production and use, and environmental protection.

Available in PDF, EPUB and Kindle. Book excerpt: Evidence has been mounting for some time that intensive row-crop agriculture as practiced in developed countries may not be environmentally sustainable, with concerns increasingly being raised about climate change, implications for water quantity and quality, and soil degradation. This volume synthesizes two decades of research on the sustainability of temperate, row-crop ecosystems of the Midwestern United States. The overarching hypothesis guiding this work has been that more biologically based management practices could greatly reduce negative impacts while maintaining sufficient productivity to meet demands for food, fiber and fuel, but that roadblocks to their adoption persist because we lack a comprehensive understanding of their benefits and drawbacks. The research behind this book, based at the Kellogg Biological Station (Michigan State University) and conducted under the aegis of the Long-term Ecological Research network, is structured on a foundation of large-scale field experiments that explore alternatives to conventional, chemical-intensive agriculture. Studies have explored the biophysical underpinnings of crop productivity, the interactions of crop ecosystems with the hydrology and biodiversity of the broader landscapes in which they lie, farmers' views about alternative practices, economic valuation of ecosystem services, and global impacts such as greenhouse gas exchanges with the atmosphere. In contrast to most research projects, the long-term design of this research enables identification of slow or delayed processes of change in response to management regimes, and allows examination of responses across a broader range of climatic variability. This volume synthesizes this comprehensive inquiry into the ecology of alternative cropping systems, identifying future steps needed on the path to sustainability.

Download or read book Crop Evolution, Adaptation and Yield written by L. T. Evans and published by Cambridge University Press. This book was released on 1996-05-02 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this major 1993 work, Lloyd Evans provides an integrated view of the domestication, adaptation and improvement of crop plants, bringing together genetic diversity, plant breeding, physiology and aspects of agronomy. Considerations of yield and maximum yield provide continuity throughout the book. Food, feed, fibre, fuel and pharmaceutical crops are all discussed. Cereals, grain legumes and root crops, both temperate and tropical, provide many of the examples, but pasture plants, oilseeds, leafy crops, fruit trees and others are also considered. After the introductory chapter, the increasing significance of crop yields to the world's food supply is highlighted. The next three chapters consider changes to crop plants over the last ten thousand years, including domestication, adaptation and improvement. Aimed at research workers and advanced students in crop physiology and ecology, agronomy and plant breeding, this book also reaches conclusions of relevance to those concerned with developmental policy, agricultural research and management, environmental quality, resource depletion and human history.
