Jan 15, 2021 · Nowadays, composting is a better option to solve these problems. Accordingly, this study explored the effects of co-composting swine manure with different inoculants dominated by Phanerochaete chrysosporium (p), Aspergillus niger (a), and Bacillus licheniformis (b) on the simultaneous removal of multiple antibiotics and resistance genes and
Jun 22, 2022 · One way to increase yields in agriculture using organic alternative is the introduction of manure-based composts into the soil. However, the use of such composts carries a risk of soil contamination with antibiotic resistance genes (ARG) from the gut and manure of the livestock. The contamination of the composts with heavy metals or antibiotics can increase this risk, while the
Jul 1, 2020 · The variation of antibiotic resistance genes (ARGs) and influential factors in pig manure composting were investigated by conducting simulated composting tests using four different supplement materials (wheat straw, corn straw, poplar sawdust and spent mushroom).
Jul 15, 2019 · Due to the intensive use of feed additives in livestock farming, animal manure has become a hotspot for antibiotics, heavy metals, and antibiotic resistance genes (ARGs). Unlike antibiotics, heavy metals cannot be degraded during composting and thus could pose a persistent co-selective pressure in the proliferation of antibiotic resistance.
May 5, 2023 · Composting pig manure can help to break down organic matter and pathogens, as well as improve soil structure and water-holding capacity. Moreover, composting pig manure can also reduce the volume and weight of manure, making it easier to handle and transport. By using pig manure as fertilizer responsibly and considering composting as an option
This equipment consists of transmission device, running gear, turning device and other main components. During turning, SEEC wheel type compost turner can blend the raw material and treated pig manure will be moved 0.7 meter to 1 meter away. By this method, you can realize high-efficiency turning and uniform blend.
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
May 15, 2017 · Successful co-composting of chestnut forest green waste and MDF sludge was achieved. Pig manure decreased the C/N ratio and increased moisture content of the mixture. Active composting process was sustained for about two months. The addition of MDF sludge strongly reduced nitrogen losses during composting.
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.
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
Jun 12, 2023 · This study was conducted to evaluate the abundance of antibiotic resistant bacteria and their resistance genes from agriculture soil supplemented with pig manure. Uncultivable soil sample was
