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
Feb 1, 2024 · The dosage was calculated based on the carbon and nitrogen content of the straw and pig manure, and the crushed straw and pig manure were thoroughly mixed to form a fluffy composting material, and a carbon to nitrogen ratio of 25:1 was secured. The water content was adjusted to 60 % using distilled water. 2.2. Experimental design
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.
Sep 19, 2023 · While the application of manure to improve soil quality has attracted attention, the effect of pig manure application rates on soil acidity remains poorly understood. In this study, we analyzed the changes and correlations between soil acidity, pH buffer capacity (pHBC), soil chemical properties, and crop yields after 8 years of pig manure application at different rates (i.e., 0, 7.5, 15, 30
Aug 1, 2020 · The influence of compound microbial agents on antibiotic resistance genes (ARGs) in pig manure composting was investigated. The results show that the addition of microbial agents promoted the
Jul 1, 2020 · By investigating the profile variation of 36 ARGs and 4 mobile genetic elements (MGEs), the succession of bacterial communities and the change in physicochemical factors during pig manure composting, this study aimed to: 1) determine the environmental behaviors and removal efficiencies of ARGs in pig manure composting; 2) determine the impact
The influence of compound microbial agents on antibiotic resistance genes (ARGs) in pig manure composting was investigated. The results show that the addition of microbial agents promoted the reduction of total ARGs and the maximum removal efficiencies for absolute abundance (77.2%) and relative abundance (64.5%) were observed in the repeated
Nov 1, 2023 · The use of phosphoric acid modified biochar reduced the abundance of 9 ARGs by 89% during a 42-day composting of pig manure (Chen et al., 2022). Qiu et al. (2022a) reported that the relative abundance of 8 target ARGs decreased by 84% during chicken manure composting supplemented with diatomite and bentonite. Due to its higher specific surface
Mix everything well and be sure to keep it moist (though not sodden) to start the decomposition action. At least once a month, head to your compost pile and turn it with a pitchfork. This will supply the compost with air, which is necessary to help get the microbes going. It will also further mix the ingredients, too.
Sep 1, 2022 · Industrial-scale aerobic composting of livestock manures with the addition of biochar: Variation of bacterial community and antibiotic resistance genes caused by various composting stages. Pengcheng Zhu, Yuxin Wu, +4 authors. Weihua Guo. Published in Environmental Pollution 1 September 2022. Environmental Science, Biology. View on PubMed. doi.org.
Turning manure is essential to composting manure. Turning compost incorporates oxygen into the system, homogenizes the pile and breaks up clumps. Turning allows more contact of manure with microbes. Producers have various ways to turn the pile. The two most common for turning compost are with a windrow turner (Figure 7) or bucket tractor.
Livestock manure is one of the most important pools of antibiotic resistance genes (ARGs) in the environment. Aerobic composting can efectively reduce the spread of antibiotic resistance risk in livestock manure. Understanding the efect of aerobic composting process parameters on manure-sourced ARGs is important to control their spreading risk.
The antibiotics removal ef ciency (except dano oxacin and. fi fl. enrooxacin) was accelerated in the early composting stage (1–14 days) by biochar. fl. addition, the pile temperature had a
