Human and veterinary antibiotics during composting of sludge

Oct 5, 2018 · Composting is an aerobic biological decomposition process where pH, C/N ratio, and moisture are controlled in the initial mixture to be composted. These key factors determine the microbial development and the organic matter stabilization. Microorganisms growing during composting reflect the evolution and the performance of the process.

Combined effects of composting and antibiotic administration

Apr 1, 2021 · Background Research is needed to delineate the relative and combined effects of different antibiotic administration and manure management practices in either amplifying or attenuating the potential for antibiotic resistance to spread. 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

Review on the fate of antimicrobials, antimicrobial

Mar 5, 2021 · Fate of hormones during composting. Several studies have evaluated composting to remove hormones in manure. After a 76-day composting study, the total concentrations of steroid hormones in beef cattle manure were reduced by up to 87% (Bartelt-Hunt et al., 2013). A study on poultry manure reported that the levels of water-soluble E2β and

Impacts of pile temperature on antibiotic resistance, metal

Nov 20, 2020 · The characteristics of the raw materials are shown in Table S1. The composting experiment was conducted on a lab-scale cylinder composting reactor (1000 mL) (Fig. S1). Each composting reactor contained 500 g of the mixed stuff and the reactor was placed in a water bath for temperature control. The entire composting process lasted for 6 weeks.

Vermicomposting: a holistic approach for sustainable crop

Apr 4, 2024 · Vermicomposting yields a valuable byproduct called vermi-wash, which enhances crop resistance against diseases, stimulates seed germination, and improves overall plant vigor.

Electric field-assisted aerobic co-composting of chicken

Jan 1, 2024 · The composting materials and composting operations were similar to those described by Tang et al. (2019) and Fu et al., (2022a). Composting experiments were carried out using three composting systems (EFAC, CAC, and CCMC) using the material mix proportions (Table 1). An electric field with a DC voltage of 5 V was applied to the compost in the

Composting Animal Manures: A guide to the process and - NDSU

Composting and utilizing compost are advantageous tools in nutrient management plans that, when managed properly, benefit crops and reduce the potential to pollute. Compost is a mixture of organic residues (manure, animal carcasses, straw, etc.) that have been piled, mixed and moistened to undergo thermophilic [high heat, 113 to 160 degrees

Cow manure compost‐based products as alternative rhizobial

Jun 24, 2023 · Cow manure compost (CMC) has been used widely as soil amendment to improve soil fertility and health, and to minimize environmental impacts. However, direct use of commercial CMC-based products as alternative rhizobial carrier materials is rare, it could promote inoculant commercialization.
