Sep 1, 2021 · Aerobic composting is commonly used to dispose livestock manure and is an efficient way to reduce antibiotic resistance genes (ARGs). Here, the effects of different quality substrates on the fate of ARGs were assessed during manure composting. Results showed that the total relative abundances of ARG
Oct 15, 2021 · The purpose of this study was to investigate the heavy metal resistant bacteria (HMRB) community succession and bacterial activity in poultry manure (PM) composting. Five different concentration of chicken manure biochar (CMB) at 0%, 2%, 4%, 6%, and 10% on a dry weight basis was applied with initial feedstock (poultry manure + wheat straw) and indicated with T1, T2, T3, T4, and T5.
Feb 1, 2022 · In addition, studies have also investigated that the succession and evolution of heavy metal resistant bacteria during composting (Zhou et al., 2021; Liu et al., 2021), which revealed heavy metal resistant bacteria played an important role in improving composting quality and efficiency. However, response strategies of microbial community to
Jul 21, 2023 · As livestock and poultry farming expands in China, the generation of fecal waste has significantly increased. Inadequate waste management can contribute to environmental pollution. This study seeks to optimize small-scale composting systems to address the inefficiencies and the limited automation of traditional composting equipment. We redesigned the mixing blades and refined the ventilation
Aug 1, 2022 · Composting organic waste compared to landfilling prevents ground water from being polluted due to leachate from landfilling organic matter (Ayilara et al., 2020). Stable compost is also much easier to handle in terms of storage and transport compared to raw organic waste which in this case is raw chicken manure (Akdeniz, 2019).
Mar 7, 2024 · The Benefits of Chicken Manure. As a non-synthetic organic fertilizer, chicken manure has numerous benefits. Nutrients: It is a complete fertilizer that contains the macronutrients nitrogen, phosphorus, and potassium, as well as important micronutrients such as calcium needed for healthy plant growth. Soil amendment: Chicken manure is more than
Feb 29, 2024 · Step 2: Building Your Compost Pile. Select a shaded spot for your compost pile or bin to protect it from drying out too quickly. A balance of green (nitrogen-rich) and brown (carbon-rich) materials is crucial. Layer your chicken manure with carbon sources like dry leaves, straw, or shredded paper to encourage aerobic decomposition, which is
Apr 1, 2023 · 3.1.2. pH. The pH of both groups increased at first with a fast and slow trend, then decreased gradually before finally stabilizing (Fig. 1 b).With the initial compost pH at 7.03, the peak pH of treatment reached 8.17, which was 6.38 % higher than the peak pH of control (7.68) (P < 0.05).
Jul 27, 2021 · ABSTRACT. Manure storage can affect the concentration and prevalence of antibiotic-resistant bacteria (ARB) and antibiotic resistance genes (ARGs) in cattle manure prior to land application. The objective of this study was to compare stockpiling and composting with respect to their effectiveness in reducing ARB and ARGs in beef cattle
Mar 15, 2021 · Totally identified top 10 bacterial community from phylum to species level as illustrated in Fig. 1, Fig. 2.The dominant phyla were Firmicutes (52.87–14.31%), Actinbacteria (35.20–4.99%), Bacteroidetes (0.05–15.07%) and Proteobacteria (0.01–20.27%) within the samples, which are ubiquitous and most abundant in composting system, and the results are similar to previous studies by Awasthi
Mar 15, 2024 · It was reported that the number of deaths due to antibiotic resistance would reach 10 million per year by 2050, which would be much higher than the number of deaths due to cancer [6]. Aerobic composting is a cost-effective way to treat organic waste by reducing the mass of organic matter while decomposing pollutants and killing pests [7].
Sep 26, 2023 · Abatement of antibiotic resistance genes (ARGs) in livestock manure by composting has attracted attention. This study investigated the effect of adding magnesium-modified biochar (MBC) on ARGs and microbial communities in chicken manure composting. Twelve genes for tetracyclines, sulfonamides, and macrolides, and mobile genetic elements were measured in the compost pile. The results showed
May 12, 2020 · The goal of this study was to determine if the composting of poultry manure at a field scale would result in the reduction of antibiotic residues, pathogenic bacteria, and antibiotic resistance genes (ARGs) in the final fertilizer product.
Sep 28, 2023 · Choose the right container: Use a compost bin or designated area to contain the chicken manure and other organic matter. Provide proper airflow: Ensure adequate aeration in the compost pile by turning it regularly or using a compost tumbler, allowing oxygen to reach the microorganisms responsible for decomposition.
Mar 3, 2023 · Compost has four ingredients: carbon, nitrogen, air, and water. Nitrogen and carbon are often described as greens and browns, but it can be deceiving – Chicken poop is definitely brown, but it’s a nitrogen source so technically “green,” just like kitchen scraps. The litter used in the coop, whether it be leaves, straw, or wood shavings
