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
Mar 15, 2022 · The compost mixture is periodically turned, which exposes the compost mixture to the air to maintain aerobic conditions and to keep composting temperature from getting too high. The turning frequency varies from 2 to 10 days, depending on the type of mix, volume, and ambient air temperature, and can be reduced as the compost ages.
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).
Enhancing the compost maturation of swine manure and rice straw by applying bioaugmentation. Wei‐Kuang Wang & Chih‐Ming Liang* Microorganisms capable of decomposing cellulose, xylan, starch
Jan 1, 2024 · At the end of composting, FM reduced the abundance of intI1, intI2, ISCR1, and Tn916/1545 by 29.7%–81.7% in FM compared with CK. The total abundance of MGEs in FM compost products was reduced by 96% compared with the initial feedstock. The results indicated that composting effectively reduced the contamination and spread of MGEs in the
Feb 1, 2022 · However, M3 bacteria had a nominal abundance at the later stage of composting, indicating they were easy to be eliminated in the process of microbial succession. The abundance of M4 bacteria was lower during L, M and H composting than that of CK composting (p < 0.05), indicating that they were susceptible to the addition of heavy metals. M Ⅲ
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.
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
Apr 21, 2021 · The current study investigated the impact of chicken litter application on the abundance of multidrug-resistant Enterococcus spp. in agricultural soil. Soil samples were collected from five different strategic places on a sugarcane farm before and after manure application for four months.
Jun 1, 2023 · The inoculation of Bacillus subtilis into cattle manure and straw composting prolonged the thermophilic phase of composting by 1–2 days and accelerated compost maturation [8]. Bacillus was inoculated into rice straw could alter the bacterial community of compost, thereby promoting the lignocellulose degradation [23] .
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.
Apr 8, 2022 · The temperature of the composting process lasted for 14 days in control composting and 18 days in composting with biochar (Fig. 1a). The extended thermophilic phase is common for this organic
Aug 11, 2022 · Background Antibiotics and antibiotic resistance genes (ARGs) used in intensive animal farming threaten human health worldwide; however, the common resistome, ARG mobility, and ARG host composition in different animal manures and mixed manure composts remain unclear. In the present study, metagenomic assembly and cross-sample mapping were used to comprehensively decipher the common resistome
Oct 3, 2022 · Antibiotic resistance caused by antibiotic resistance genes (ARGs) threatens human health. ARGs in animal manure can be degraded by composting. This study explored the changes in ARGs and microbial communities during co-composting of pig manure and tea stalks with (T) thermophilic microbial agents, including Geobacillus toebii ZF1 and Geobacillus sp. ZF2 for 15 days in a 4 L vacuum flask
