Book Synopsis Physicochemical Transformations of Manure to Reduce Greenhouse Gas Emissions, Improve Nutrient Use, and Minimize Environmental Impacts of Dairy Operations by : Rylie Jo Ellison

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.

This book was released on 2013-11-21 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes guidelines prepared by the U.S. Country Studies Program for the evaluation of options to mitigate greenhouse gas emissions. The U.S. Country Studies Program developed these guidelines in collaboration with Lawrence Berkeley National Laboratory to provide developing countries and countries with economies in transition with reference materials for national mitigation assessments. Over 50 countries participating in the program have used the guidelines, which have been refined to reflect their comments. The guidelines delineate a step-wise methodology for evaluating greenhouse gas mitigation options for the energy and non-energy sectors and describe the applications of common analytical tools. The U.S. Country Studies Program uses these guidelines in conjunction with intensive training workshops and follow up technical assistance during the lifetime of each country's study. The program uses similar reference materials to assist counties with their greenhouse gas emission inventories and evaluations of climate change vulnerability and adaptive responses. These guidelines serve three purposes: to assist countries in making decisions about the scope and methodology for mitigation assessments; to provide countries with guidance and step-by-step instructions on each element of a mitigation assessment; and to help countries determine which analytical tools are best suited to their needs and describe procedures for applying these tools. This book describes the application of the most common and readily available methods and analytical tools. Countries are encouraged, where appropriate, to use their own methods.

This book was released on 2021-05-27 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Like many other economies in transition, Kyrgyzstan, Tajikistan and Uzbekistan face the dual challenge of promoting development and reducing greenhouse gas (GHG) emissions, and ruminant systems are central for achieving both goals. Given the important economic, nutritional and environmental roles that ruminant systems play in Central Asia, Kyrgyzstan, Tajikistan and Uzbekistan, we conducted a GHG assessment (based on Tier 2 methodology according 2006 IPCC Guidelines) to understand the role of ruminants and grasslands in emissions and soil organic carbon sequestration in the region. This study found that enteric methane and manure management are the predominant sources of emissions from cattle systems; however, the study found that regions with high GHG emissions from the cattle systems also had the highest soil carbon stocks. This is mainly due to the high apportion of carbon into the soil from manure and organic amendments. Thus, in these regions, tailored practices could likely reduce GHG emissions through practices that can increase organic carbon storage. This project was the first step in understanding the role of ruminants through advanced GHG accounting methods and serve as a basis for these countries to take on larger climate investment projects and catalyse climate action through sustainable livestock development.

Del Grosso and published by John Wiley & Sons. This book was released on 2020-01-22 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crop, livestock, and forestry productions systems are important sources and sinks of greenhouses gases, but estimates of the magnitude of gas fluxes are more uncertain than those for other economic sectors such as transportation and electricity generation. Recent improvements in process-level un-derstanding, modeling software, and observational data used for model testing have increased the accuracy of model predictions, but substantial uncertainty remains, particularly regarding the potential for different management practices to mitigate emissions. The chapters in this volume demonstrate that both simple methods and complex models have strengths and limitations depending on stake-holder interest, scale of application, and other factors. Future improvement can be facilitated by or-ganizing model input and testing data into web-accessible databases and by making model algorithms more available and transparent.
