Innovative Animal Manure Management for Environmental Protection, Improved Soil Fertility and Crop Production
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.
Industrial Farm Animal Production, the Environment, and Public Health
Essential essays on the environmental impacts of factory farms on public health. The rapid—and relatively recent—concentration of food animal production into factory farms makes meat plentiful and cheap, but this type of agriculture comes at a great cost to human health and the environment. In Industrial Farm Animal Production, the Environment, and Public Health, editors James Merchant and Robert Martin bring together public health experts to explore the most critical topics related to industrial farm animal production. The environmental impacts of these concentrated animal-feeding operations endanger the health of farm and meatpacking workers, neighbors, and surrounding communities. Fac...
Proceedings of the National Conference on Next-Generation Sustainable Technologies for Small-Scale Producers (NGST 2022)
This is an open access book.To create a road map for developing and delivering the next generation of soil, air and water technologies in support of sustainable production systems on small and limited resource farms; identify gaps, needs and recommendations for NIFA; and ensure access to technology with consideration for affordability and applicability.
Advances in Hurricane Research
This book provides a wealth of new information, ideas and analysis on some of the key unknowns in hurricane research. Topics covered include the numerical prediction systems for tropical cyclone development, the use of remote sensing methods for tropical cyclone development, a parametric surface wind model for tropical cyclones, a micrometeorological analysis of the wind as a hurricane passes over Houston, USA, the meteorological passage of numerous tropical cyclones as they pass over the South China Sea, simulation modelling of evacuations by motorised vehicles in Alabama, the influence of high stream-flow events on nutrient flows in the post hurricane period, a reviews of the medical needs, both physical and psychological of children in a post hurricane scenario and finally the impact of two hurricanes on Ireland. Hurricanes discussed in the various chapters include Katrina, Ike, Isidore, Humberto, Debbie and Charley and many others in the North Atlantic as well as numerous tropical cyclones in the South China Sea.

New Processes for Nutrient Recovery from Wastes
Global demand for mineral fertilizers is continuously increasing, while large amounts of organic wastes are being disposed without use as a resource, resulting in soil, water and air pollution. Current trends of intensification, expansion and agglomeration of livestock production result in a net import of nutrients that lead to a surplus in some production areas. Therefore, new processes and technologies to recover and re-use nutrients from both solid and liquid wastes are desirable to close the loop on the nutrient cycle in modern human society and address future scarcity of non-renewable nutrients and fossil-based fertilizers. This Research Topic aims to present scientific progress regarding processes and technologies that allow recovery and re-use of nutrients from wastes, the selective recovery of mineral nutrients (ammonia and phosphates), the production of new organic fertilizers, and evaluation of their relative agronomic efficiency. The articles within provide a stronger recognition of the importance of nutrient recovery and upcycling in the new horizons of the circular economy.
