Book Description
The majority of meat, milk, and eggs consumed in the United States are produced in concentrated animal feeding operations (CAFO). With concentrated animal operations, in turn comes concentrated manure accumulation, which can pose a threat of contamination of air, soil, and water if improperly managed. Animal Manure: Production, Characteristics, Environmental Concerns, and Management navigates these important environmental concerns while detailing opportunities for environmentally and economically beneficial utilization.

Book Description
About 5% of all U.S. cropland is currently fertilized with livestock manure. Expanded environmental regulation through nutrient management plans will likely lead to wider use of manure on cropland, at higher production costs, but with only modest impacts on commodity demand, or farm structure. While current use is limited, expanded gov¿t. support could lead to a substantial increase in manure use as a feedstock. However, current energy processes are unlikely to compete with fertilizer uses of manure, because they leave fertilizer nutrients as residues, in more marketable form, and because manure-to-energy projects will be most profitable in regions where raw manure is in excess supply, with the least value as fertilizer. Charts and tables.

Book Description
The rapidly changing nature of animal production systems, especially increasing intensification and globalization, is playing out in complex ways around the world. Over the last century, livestock keeping evolved from a means of harnessing marginal resources to produce items for local consumption to a key component of global food chains. Livestock in a Changing Landscape offers a comprehensive examination of these important and far-reaching trends. The books are an outgrowth of a collaborative effort involving international nongovernmental organizations including the United Nations Food and Agriculture Organization (UN FAO), the International Livestock Research Institute (ILRI), the Swiss College of Agriculture (SHL), the French Agricultural Research Centre for International Development (CIRAD), and the Scientific Committee for Problems of the Environment (SCOPE). Volume 1 examines the forces shaping change in livestock production and management; the resulting impacts on landscapes, land use, and social systems; and potential policy and management responses. Volume 2 explores needs and draws experience from region-specific contexts and detailed case studies. The case studies describe how drivers and consequences of change play out in specific geographical areas, and how public and private responses are shaped and implemented. Together, the volumes present new, sustainable approaches to the challenges created by fundamental shifts in livestock management and production, and represent an essential resource for policy makers, industry managers, and academics involved with this issue

Book Description
A rapidly changing and expanding livestock and poultry production sector is causing a range of environmental problems on local, regional and global scales. Animal Manure Recycling: Treatment and Management presents an accessible overview of environmentally friendly technologies for managing animal manure more efficiently and in a sustainable manner. The book describes the physical and chemical characteristics of animal manure and microbial processes, featuring detailed examples and case studies showing how this knowledge can be used in practice. Readers are introduced to the sustainable use of animal manure for crop fertilisation and soil amelioration. Environmentally friendly technologies for reducing emissions of ammonia, odour and the greenhouse gases nitrous oxide and methane are presented, and reduction of plant nutrient losses using separation technologies is introduced. Finally and most importantly, the book describes methods to commercialise and transfer knowledge about innovations to end-users. Topics covered include: Regulation of animal manure management Manure organic matter: characteristics and microbial transformations Greenhouse gas emissions from animal manures and technologies for their reduction Technologies and logistics for handling, transport and distribution of animal manures Bioenergy production Animal manure residue upgrading and nutrient recovery in bio-fertilisers Life cycle assessment of manure management systems Innovation in animal manure management and recycling Animal Manure Recycling: Treatment and Management presents state-of-the-art coverage of the entire animal manure chain, providing practical information for engineers, environmental consultants, academics and advanced students involved in scientific, technical and regulatory issues related to animal manure management.

Table of Contents Knowing the Value of Green Manure Using green manure for a richer fertile soil Table of Contents Introduction A Green Manure Experiment The Green Manure Revolution Taking Care Of the Green Manure Crop Types of Green Manures Mustard As a Green Fertilizer Ryegrass Purifying “Dirty” Land “The Little Man” Paucity of Water? Conclusion Lime in Your Soil Author Bio Publisher Introduction A good example of green manure – Phacelia tanacetifolia For a number of us gardeners out there, experienced as well as newbies, the moment somebody tells us about nourishing the soil, our minds immediately go back straight to the packages of chemical fertilizer that we have bought so recently. And if we are organically minded, we think of the compost that has been decomposing in one corner of our garden, for the past 6 months. I wrote a book called Feeding the Hungry Soil about how you can feed the hungry side with a large amount of natural compost, leaf compost, poultry manure, and bone meal and other ways in which the soil can replenish the nourishment which it has lost during the growing of your harvest. If you are interested in knowing more about this particular essential area of helping your garden to grow naturally you can purchase this book on Amazon. This book is a continuation of how you can keep feeding the land. Naturally, you are going to be using time-tested and timeworn methods, which have been used for millenniums, and which have never poisoned the earth. Not many people know about green manuring. When I spoke about this to a horticulturalist friend, he said in a really tired sort of way – oh, you so boring botanists, whatever will you think up next? When I told him all about green manuring, he told me that he really did not have the time and the energy to promote this particular face of agriculture in his agriculture college, because really, who would like to dig deep in the ground, and put in green fertilizer? He had much better and less wearying things to do. When I told him that this was the way in which city soil in which the sand content was really high, could be made fertile again, he told me to experiment beforehand, and show him the proof, in a herb garden, so that he may think of applying this part of gardening know-how in his agricultural curriculum and practical practice. So, why am I advocating green manuring? If you are a person of Faith, just look around you. Give thanks to the bounty given to you by Mother Nature and by God. After that, you may want to look at the holy Bible. In Leviticus, God said that the land has to rest every 7 years.

Book Description
In his insightful new book, Holy Shit: Managing Manure to Save Mankind, contrary farmer Gene Logsdon provides the inside story of manure-our greatest, yet most misunderstood, natural resource. He begins by lamenting a modern society that not only throws away both animal and human manure-worth billions of dollars in fertilizer value-but that spends a staggering amount of money to do so. This wastefulness makes even less sense as the supply of mined or chemically synthesized fertilizers dwindles and their cost skyrockets. In fact, he argues, if we do not learn how to turn our manures into fertilizer to keep food production in line with increasing population, our civilization, like so many that went before it, will inevitably decline. With his trademark humor, his years of experience writing about both farming and waste management, and his uncanny eye for the small but important details, Logsdon artfully describes how to manage farm manure, pet manure and human manure to make fertilizer and humus. He covers the field, so to speak, discussing topics like: How to select the right pitchfork for the job and use it correctly How to operate a small manure spreader How to build a barn manure pack with farm animal manure How to compost cat and dog waste How to recycle toilet water for irrigation purposes, and How to get rid ourselves of our irrational paranoia about feces and urine. Gene Logsdon does not mince words. This fresh, fascinating and entertaining look at an earthy, but absolutely crucial subject, is a small gem and is destined to become a classic of our agricultural literature.
