Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: Whole farm nutrient budgets (WFNB) enable producers to link dairy herd management with traditional field nutrient management plans. The objective of this study was to calculate WFNBs of nitrogen, phosphorus, and potassium (N, P, and K) at a commercial farm in New Brunswick and in Prince Edward Island. Reliable estimates of N fixation from alfalfa and red clover on the farms were obtained with adjustments to the Høgh-Jensen et al. (2004) dry matter conversion models. The farms had surpluses of N, P, and K. Both farms imported feed as well as nutrient inputs for crop production. Surpluses of all nutrients were typical in comparison to WFNBs of similar dairy farms; however, the nutrient use efficiencies were low. The imported manure and fertilizer used in the crop production components contributed to surpluses of N and P which could likely be reduced to improve overall farm nutrient use efficiency.

This book was released on 2017-02-17 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agricultural Systems, Second Edition, is a comprehensive text for developing sustainable farming systems. It presents a synthetic overview of the emerging area of agroecology applications to transforming farming systems and supporting rural innovation, with particular emphasis on how research can be harnessed for sustainable agriculture. The inclusion of research theory and examples using the principles of cropping system design allows students to gain a unique understanding of the technical, biological, ecological, economic and sociological aspects of farming systems science for rural livelihoods. This book explores topics such as: re-inventing farming systems; principles and practice of agroecology; agricultural change and low-input technology; ecologically-based nutrient management; participatory breeding for developing improved and relevant crops; participatory livestock research for development; gender and agrarian inequality at the local scale; the nature of agricultural innovation; and outreach to support rural innovation. The extensive coverage of subjects is complemented with integrated references and a companion website, making this book essential reading for courses in international agricultural systems and management, sustainable agricultural management, and cropping systems. This book will be a valuable resource for students of agricultural science, environmental engineering, and rural planning; researchers and scientists in agricultural development agencies; and practitioners of agricultural development in government extension programs, development agencies, and NGOs. Provides students with an enhanced understanding of how research can be harnessed for sustainable agriculture Incorporates social, biological, chemical, and geographical aspects important to agroecology Addresses social and development issues related to farming systems

This book was released on 2020-12-04 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: New York City's municipal water supply system provides about 1 billion gallons of drinking water a day to over 8.5 million people in New York City and about 1 million people living in nearby Westchester, Putnam, Ulster, and Orange counties. The combined water supply system includes 19 reservoirs and three controlled lakes with a total storage capacity of approximately 580 billion gallons. The city's Watershed Protection Program is intended to maintain and enhance the high quality of these surface water sources. Review of the New York City Watershed Protection Program assesses the efficacy and future of New York City's watershed management activities. The report identifies program areas that may require future change or action, including continued efforts to address turbidity and responding to changes in reservoir water quality as a result of climate change.
Download or read book Organic Farm Management Handbook 2023 written by Nic Lampkin and published by Organic Research Centre. This book was released on 2023-09-30 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Organic Farm Management Handbook from the Organic Research Centre is the only source of information on the costs and performance of organic farming. One of the key barriers is the lack of current information on the costs and business performance of organic farms and related management issues that is vital to anyone contemplating the seismic shift to organic farming. The revised OFMH will provide that information – utilising in depth historical data and expert opinion. It is the essential tool for understanding the economics of organic farming in the UK. It can: Help with business plans and budgets Provide a means of assessing the viability of specific crops and livestock Advise on conversion related innovations such as new marketing approaches.

Available in PDF, EPUB and Kindle. Book excerpt: Long-Term Farming Systems Research: Ensuring Food Security in Changing Scenarios presents the legacy and heritage of Long-Term Experiments (LTEs) in Agriculture while also addressing the challenges and potential solutions. The book discusses how LTEs form an important asset in understanding agriculture’s significant influence on life on earth. As global governments and development agencies try to achieve the Global Sustainable Development Goals (SDGs) of the United Nations, this book’s content is of unprecedented importance, providing insights into the interactions of agricultural production with ecological, economic and societal aspects. In this regard, this book offers a thorough resource of information based on experiences from various ongoing LTEs in different parts of the world. The contextual variety and geographic diversity presented in this book makes it useful for agricultural and environmental scientists, as well as students and educators in such fields. --- From the Editors: "Thanks to the excellent panel of our contributing authors, in this book, we have attempted to offer the widest possible thematic and geographical coverage on LTEs. Experts from different institutions leading LTEs across the globe have provided their perspectives on different aspects of LTEs, not only highlighting the unique knowledge contribution of LTEs, but also discussing the unique challenges of effectively managing LTEs and maintaining their relevance to changing scenarios. We hope that this book will offer something for everyone interested in the history, present and future of our agroecosystem." Provides a comprehensive resource of information generated in various LTEs across the globe, with a focus on various aspects of farming systems, crop management practices, plant, soil and human nutrition as well as on capacity development Presents a holistic view on interactions of agricultural production and its relationship to the environment and society Identifies challenges and lessons learned from different LTEs and provides recommendations for potential solutions

Download or read book Organic Crop Production Ambitions and Limitations written by Holger Kirchmann and published by Springer Science & Business Media. This book was released on 2008-12-16 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many people believe that organic agriculture is a solution for various problems related to food production. Organic agriculture is supposed to produce healthier products, does not pollute the environment, improves the fertility of soils, saves fossil fuels and enables high biodiversity. This book has been written to provide scientifically based information on organic agriculture such as crop yields, food safety, nutrient use efficiency, leaching, long-term sustainability, greenhouse gas emissions and energy aspects. A number of scientists working with questions related to organic agriculture were invited to present the most recent research and to address critical issues. An unbiased selection of literature, facts rather than standpoints, and scientifically-based examinations instead of wishful thinking will help the reader be aware of difficulties involved with organic agriculture. Organic agriculture, which originates from philosophies of nature, has often outlined key goals to reach long-term sustainability but practical solutions are lacking. The central tasks of agriculture - to produce sufficient food of high quality without harmful effects on the environment - seem to be difficult to achieve through exclusively applying organic principles ruling out many valuable possibilities and solutions.
