Jan 1, 2021 · The fate of antibiotic resistance genes in cow manure composting: shaped by temperature-controlled composting stages ARGs, including tetC, tetG, and tetW, were enhanced by 198.77 %, 846.77 % ...
Jul 27, 2023 · In doing so, we developed a novel cow manure composting apparatus based on the target composting quantity method. The new design features a refined ventilation and heating structure, as well as an enhanced control system using PLC and MCGS.
Jun 14, 2021 · Composted cow manure fertilizer makes an excellent growing medium for garden plants. When turned into compost and fed to plants and vegetables, cow manure becomes a nutrient-rich fertilizer. It can be mixed into the soil or used as top dressing. Most composting bins or piles are located within easy reach of the garden.
Jan 1, 2024 · Livestock manure use in agriculture contributes to pollutants like antibiotic resistance genes (ARGs) and resistant bacteria. This practice could potentially facilitate ARGs development in soil ecosystems. Our study aimed to explore ARGs and bacterial communities in cattle manure from Ningxia beef cattle farms with varying breeding periods.
Aug 1, 2023 · This study evaluated the effects of adding mature compost on the decomposition and microbial communities in the aerobic composting of cattle manure. The addition of mature compost shortens the composting cycle and results in a final lignocellulosic degradation rate of 35%.
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.
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
Dec 26, 2023 · It is an excellent source of organic matter, nutrients, and beneficial microorganisms. When applied to the soil, composted cow manure improves soil fertility, enhances nutrient availability, and promotes a healthy soil ecosystem. It also helps to retain moisture in the soil, reducing the need for frequent watering.
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
Jul 1, 2022 · Composting is an effective and necessary modality in the recycling of agricultural wastes such as livestock manure, furfural, and straw. However, the risks of heavy metals (HMs) and antibiotic
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
Dec 7, 2023 · Enhanced corrosion and wear resistance of Zn–Ni/Cu–Al 2022/11/21/ · In order to improve the cathodic protection and wear resistance of cold spraying Zn-based coatings, Zn–Ni/Cu–Al2O3 composite coating was prepared by co-depositing Zn powders, nickel-coated Cu powders, and Al2O3 powders on the steel substrate using the low
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.
Evaluating potential environmental and clinical impacts of industrial antibiotic use is critical in mitigating the spread of antimicrobial resistance. Using soil columns to simulate field application of swine or cattle manure and subsequent rain events, and a targeted qPCR-based approach, we tracked resistance genes from source manures and identified important differences in antimicrobial
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.
