Apr 1, 2021 · Here, we carried out a comprehensive parallel examination of the effects of small-scale (> 55 °C × 3 days) static and turned composting of manures from dairy and beef cattle collected during
Create the compost pile: Build a compost pile in a designated area of your garden or use a compost bin. Layer the cow manure and organic materials, making sure to maintain the carbon-to-nitrogen ratio of 30-to-1. Keep it moist: Water the compost pile regularly to keep it moist but not soggy.
Sep 5, 2016 · Livestock manure is often subjected to aerobic composting but little is known about the variation in antibiotic resistance genes (ARGs) during the composting process under different concentrations of antibiotics. This study compared the effects of three concentrations of oxytetracycline (OTC; 10, 60
May 31, 2015 · Fate of Antibiotics and Antibiotic Resistance during Digestion and Composting: A Review. al., 2014). The presence of antibiotics and antibiotic resistance genes (ARGs) in cattle manure and swine manure has also been well documented. For example, Chen et al. (2007) reported up to 3.69 and 5.00 to 9.22 log copies g-1 of erythromycin resistance
Mar 15, 2021 · Antibiotic resistance genes (ARGs) have been diffusely detected in several kinds of organic solid waste, such as livestock manure, sludge, antibiotic fermentation residues, and food waste, thus attracting great attention. Aerobic composting, which is an effective, harmless treatment method for organic solid waste to promote recycling, has been identified to also aid in ARG reduction. However
Jul 27, 2021 · 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 manure in a
Apr 5, 2024 · Use a compost turner, like a shovel or pitchfork, to move the compost from the edges to create another pile. Shovel the compost from the middle of the original pile onto the new one. Water the manure again and let it sit until the cow dung compost reaches 130°F for three straight days.
Mar 6, 2024 · Our results demonstrate that composting reduced more high-risk resistance genes at the transcriptomic level in cattle manure than conventional stockpiling. This finding not only underscores the effectiveness of composting in reducing antibiotic resistance in manure but also highlights the importance of employing RNA analyses alongside DNA analyses.
Feb 1, 2024 · Simplified inoculation lifted cow-manure composting performance at industrial-scale. • Inoculation raised temperature by 7–10 °C, extending 50 °C + period from 12 to 26 days. • Key bacteria Bacillus, Lysinibacillus, Clostridium thrived during thermophilic stage. •
4 Best Compost Machines for Beginner Composters - GreenCitizen. This Countertop Compost Machine Turns Scraps into Compost in . Mar 27, 2024 · The Lomi countertop compost machine makes turning kitchen scraps into compost the easiest thing ever.
Jul 21, 2023 · This study was designed to investigate the efficiency of improved composting equipment in enhancing the composting process of livestock manure. The optimized equipment addresses issues of poor mixing effect, low automation level, and extended composting cycles in traditional composting .
Dec 26, 2023 · Composted cow manure has many advantages. It helps improve soil structure, enhances moisture retention, and promotes the growth of beneficial microorganisms. Additionally, composted cow manure has a more neutral pH compared to fresh or aged manure, making it suitable for a wider range of plants.
Jan 14, 2022 · Previous studies reported that inoculation of microbes into the composting led to improved mineralization , accelerated the composting process of OPEFB from 64 days to 50 days and enhanced the compost maturity of rice straw and cattle manure by an increase in total nitrogen, phosphorus and potassium content .
Oct 15, 2023 · During composting, pH is a crucial indicator of microbial activity and population composition [51].The variation in pH values during composting is also shown in Fig. 1.At the start of the composting process (Day 0), the pH of BPA pile mixture was 4.3, known to be due to food waste acidification, which produces organic acids as well as some volatile acids of low-molecular-weight
Jun 15, 2022 · 1. Introduction. Globally, more than half of all antibiotics produced are used in animal husbandry (Van Boeckel et al., 2017; Wang et al., 2019).The larger amount of antibiotics utilization produced selective pressure for microbe in livestock fermentation systems to obtain and remain antibiotic resistance genes (ARGs), and the resistant ability was fostered gradually by the enrichment of the
