This book was released on 2020-01-03 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traditionally, livestock manure has been used to provide nutrients for plant growth and to improve soil conditions. However, the increase in concentrated animal feeding operations (CAFOs) results in high levels of plant nutrients, such as nitrogen and phosphorus, in the proximal crop and pasturelands as a result of applying more manure than what is required to meet the local plant nutrient demand. Soil runoff and leaching of land-applied manure can enrich the surface and ground water with nitrogen and phosphorus, leading to eutrophication and hypoxia. In addition, overapplication of animal manure contributes to pathogen spread, the release of hormones and other pharmaceutically active compounds, and the emission of ammonia, greenhouse gases, and odorous compounds. In this Special Issue, we present 11 interesting articles covering the production of renewable energy and fuels, extraction of ammonia from animal manure, the agricultural and environmental benefits of using animal manure or its derived materials such as biochar or ashes, and the difference in microbial communities and pathogen survival after anaerobic lagoon treatment.

Available in PDF, EPUB and Kindle. Book excerpt: Global climate change is a natural process that currently appears to be strongly influenced by human activities, which increase atmospheric concentrations of greenhouse gases (GHG). Agriculture contributes about 20% of the world’s global radiation forcing from carbon dioxide, methane and nitrous oxide, and produces 50% of the methane and 70% of the nitrous oxide of the human-induced emission. Managing Agricultural Greenhouse Gases synthesizes the wealth of information generated from the GRACEnet (Greenhouse gas Reduction through Agricultural Carbon Enhancement network) effort with contributors from a variety of backgrounds, and reports findings with important international applications. Frames responses to challenges associated with climate change within the geographical domain of the U.S., while providing a useful model for researchers in the many parts of the world that possess similar ecoregions Covers not only soil C dynamics but also nitrous oxide and methane flux, filling a void in the existing literature Educates scientists and technical service providers conducting greenhouse gas research, industry, and regulators in their agricultural research by addressing the issues of GHG emissions and ways to reduce these emissions Synthesizes the data from top experts in the world into clear recommendations and expectations for improvements in the agricultural management of global warming potential as an aggregate of GHG emissions
Download or read book Methane and Climate Change written by Peter Smith and published by Earthscan. This book was released on 2010 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Methane is a powerful greenhouse gas and is estimated to be responsible for approximately one-fifth of man-made global warming. Per kilogram, it is 25 times more powerful than carbon dioxide over a 100-year time horizon -- and global warming is likely to enhance methane release from a number of sources. Current natural and man-made sources include many where methane-producing micro-organisms can thrive in anaerobic conditions, particularly ruminant livestock, rice cultivation, landfill, wastewater, wetlands and marine sediments. This timely and authoritative book provides the only comprehensive and balanced overview of our current knowledge of sources of methane and how these might be controlled to limit future climate change. It describes how methane is derived from the anaerobic metabolism of micro-organisms, whether in wetlands or rice fields, manure, landfill or wastewater, or the digestive systems of cattle and other ruminant animals. It highlights how sources of methane might themselves be affected by climate change. It is shown how numerous point sources of methane have the potential to be more easily addressed than sources of carbon dioxide and therefore contribute significantly to climate change mitigation in the 21st century."--Publisher's description.

Download or read book Physicochemical Transformations of Manure to Reduce Greenhouse Gas Emissions Improve Nutrient Use and Minimize Environmental Impacts of Dairy Operations written by Rylie Jo Ellison and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Storage and agricultural applications of manure often result in significant loss of carbon, nitrogen, and phosphorus to the environment through volatilization and leaching. In California, manure management is estimated to be the largest source of greenhouse gas emissions from agriculture, mainly as methane (CH4) and nitrous oxide (N2O), with dairy operations being a key contributor. One of the main challenges with using animal wastes as nutrient sources is the unpredictable nitrogen mineralization rate for crop uptake. Many dairies limit application of manure organic nitrogen to prevent groundwater contamination. With a large range of dairy sizes and types of manure management systems in California, there is also a need for a variety of manure treatment technologies to address these problems. Treatments examined in this dissertation are two physicochemical techniques: chemical solid-liquid separation (coagulation) and hydrodynamic cavitation with chemical stabilization. Physically and chemically transforming animal wastes to exhibit a predictable nitrogen mineralization response is an important research and development priority. Generating a stabilized and easily transportable fertilizer from manure can help reduce environmental concerns related to on-farm nutrient management and enhance the economic feasibility for dairies. Enhancing solid-liquid separation with chemical coagulants traditionally used in wastewater treatment can isolate dissolved and particulate organic matter and phosphorus from manure into stabilized solids (flocs) while leaving the plant-available ammonium-N in the liquid fraction (effluent). In this research, a range of coagulants, including metal salts and organic polymers were tested with multiple dairy process wastewaters. The effects of chemical coagulation on the composition of the separated manure fractions, and the resulting impact on greenhouse gases and nutrient cycling are extensively explored through a series of laboratory incubations of manure effluents and manure-amended soils. Anaerobic incubations of the effluent fractions were performed to determine how both removing coagulated solids from manure process wastewater or leaving coagulated manure flocs in anaerobic storage affects greenhouse gases, CH4 in particular. This simulates how greenhouse gases from anaerobic storage ponds, or lagoons, on dairies would be affected by this treatment practice. In each incubation, regardless of coagulant type or separation of solids, CH4, and/or CO2 and N2O were significantly reduced. Several aerobic soil incubations simulated how adding coagulated manure flocs or effluents would impact the nutrient cycling of chemically separated manures applied to agricultural soils. Coagulation generally tended to stabilize organic matter, and slow C, N, and P mineralization of the solid floc fraction, depending on the type of coagulant used. This could potentially increase C sequestration and reduce nutrient runoff on dairies; however, farmers would need to manage for less nutrient availability. Lastly, the potential for hydrodynamic cavitation to be employed in a dairy manure treatment system was explored. The effects of hydrodynamic cavitation on manure were to break down organic matter and increase nitrogen availability, which could help in regulating the rate of nitrogen mineralization from manure. Hydrodynamic cavitation is also used for sterilization, which could be another benefit for manure applications. However, further work is needed to determine the efficacy of hydrodynamic cavitation for treating manure at a larger scale.
