Feb 1, 2024 · Greenhouse gas (GHG) emissions from manure management processes deserve more attention. Using three industrial-scale experiments, this study comprehensively evaluated the effects of different aeration coupled with semi-permeable membrane-covered strategies on the structure and function of bacterial communities and their impact on GHG emissions during dairy manure aerobic composting.
Jul 18, 2023 · Key Points. Cattle manure is a valuable source of key nutrients including nitrogen (N), phosphorus (P), potassium (K), sulphur (S), magnesium (Mg), and calcium (Ca), as well as certain micronutrients. Cattle manure is a dilute fertilizer due to its high content of water and organic materials. Manure with straw and bedding is an excellent source
This review article presented the current status and traditional agricultural waste (livestock manure and crop straws) utilization , the art of aerobic fermentation process including ultrahigh temperature fermentation and composting. The selection of livestock manure and crop straws as agricultural waste for this review article is due to
2023/3/22/ · Developing new uses and markets for manure may result in both economic and environmental benefits. The ERS report, Increasing the Value of Animal Manure for Farmers (AP-109, March 2023), uses data from the USDA Agricultural Resource Management Survey (ARMS) to describe current manure production, handling, storage,
Aug 1, 2023 · The production of organic fertilizer by aerobic composting of cattle manure is an important way of its resource utilization. This study evaluated the effects of adding mature compost on the decomposition and microbial communities in the aerobic composting of cattle manure.
For example, N is recommended at rates of 50 or 100 kg ha −1 year −1 from chemical fertilizer and at rates of 30–60 tons ha −1 of cattle manure for the first year of saffron production. Composted cattle manure at a rate of 60 tons ha −1 is among the suggested recommendations for sustainable saffron production (Dobermann and Cassman
Oct 16, 2019 · Thus, C60 can be recommended for cattle manure composting because of its nutrient conservation and mitigation of major gas and GHG emissions. Schematic of the experimental setup.
Elevated temperature is necessary to destroy pathogens and weed seeds in manure or other organic materials. Environmental Protection Agency (EPA) regulations for composting municipal waste require that the temperature be maintained at 131oF or above for at least three days to destroy pathogens.
Manure Composting. Composting is one of the best ways to store manure and improve soil structure and fertility. For beef enterprises, composting can reduce odors and flies, minimize nitrogen losses, decrease pathogens, and provide a consistent supply of organic fertilizer. For an effective cow manure compost, mixing and turning is essential.
Oct 1, 2010 · Composting cattle manure produces a stabilized product that leads to the development of microbial populations, which causes numerous physico-chemical changes in the waste mixture (Cai et al., 2007) and improves the handling characteristics of manure by reducing volume and weight (Eghball and Power, 1999, Adamtey et al., 2009).
Aug 3, 2016 · Results: e data revealed the nutrient loading coe cients (NLCs) of VS, TN, and TP on. agricultural land were 1.48, 0.60, and 0.66, respectively. ese values indicat ed that the loss. of nitrogen
Nov 1, 2021 · The results showed that the industrial mixed-material composting mode was beneficial to the continuation of the high-temperature period for composting (the heat lasts for 20 days), and the high
Apr 2, 2024 · We used microbiology and molecular biology techniques to screen out high-temperature and low-temperature-resistant saprobiotics for compost and prepared a compound fermentation bacteria agent to rapidly ferment cattle manure into high-quality organic fertilizer in low-temperature season. Conventional composting and high-throughput techniques were used to analyze the changes of physical and
May 1, 2024 · This study is expected to improve the understanding of how contaminated livestock manure can be effectively utilized. 2. Materials and 2.1. Composting process. Fresh dairy cattle manure and wheat straw were obtained from Jinyindao Farm in Daxing, Beijing and wheat fields in Lianyungang, Jiangsu Province, respectively.
While the Shannon diversity varied between manure compost types, the diversity of sheep and cattle manure composts were significantly higher compared to pig and chicken manure composts at both composting phases (bacteria: F 1,23 = 12.5, P = 0.002; fungi: F 1,23 = 6.07, P = 0.022, Figures 2A,B).
