Feb 21, 2024 · The whole manure composting process can be divided into three reaction phases according to the temperature profile. At the beginning of manure composting, it was the mesophilic stage from day 4 to 20 (Fig. S1a). The temperature at the day 20 was above 50 °C, indicating that the manure composting enters to the thermophilic phase (Fig. S1a).
Oct 25, 2020 · Soil health is the capacity of the soil to provide an environment for optimum growth and development of plants, while also ensuring the health of animals and humans. Animal manure has been used for centuries as a source of nutrients in agriculture. However, many other soil properties that contribute to soil health are affected when manure is applied. Bulk density, aggregate stability
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
In total, 16 manure samples were found to be mcr-1 positive, with a detection frequency of 31% in 51 samples. The numbers of mcr-1 gene copies in 12 positive manure samples with a high prevalence of mcr-1 were 10 7 -10 9 copies/g dry weight. During composting, >90% of mcr-1 in the manure was eliminated in 15 days at high temperature (44-65 °C

Mar 1, 2020 · Abstract. Composting has been widely used to turn livestock manure into organic fertilizer. However, livestock manure contains various contaminants including antibiotics and antibiotic resistance genes (ARGs). Here we investigated the variation of antibiotic resistome and its influencing factors during a commercial livestock manure composting.
Apr 15, 2021 · In another composting experiment conducted by Chang et al. (2019a), it has been reported that SRGs (sul1 and sul2) were overwhelmingly increased from 1.2 × 10 8 to 1.2 × 10 11 copies per gram of dry compost.
