Feb 7, 2022 · Accordingly, developing novel strategies to mitigate the reductive dissolution of the iron oxide component in the passive film of stainless steel would impart improved corrosion resistance. )
Jun 30, 2021 · The composting process involves mixing prescribed amounts of dead birds, poultry litter, a carbon source such as straw, and water. Caked or used poultry litter (usually pine shavings, sawdust, peanut hulls, or rice hulls) and manure is the primary compost medium. These materials supply ammonia nitrogen for the growth of bacteria.
Mar 15, 2021 · Currently, during the composting process, ARGs were mainly affected by three response pathways, (I) “Microenvironment-ARGs”; (II) “Microenvironment-microorganisms-ARGs”; (III) “Microorganisms-horizontal gene transfer-ARGs”, respectively.
Feb 1, 2023 · The coating exhibits excellent corrosion resistance against lead−bismuth eutectic (LBE) compared with the uncoated T91 steel. The results show that the AlTiCrFeMoSi HEA coating has great
May 12, 2020 · The goal of this study was to determine if the composting of poultry manure at a field scale would result in the reduction of antibiotic residues, pathogenic bacteria, and antibiotic resistance genes (ARGs) in the final fertilizer product. A 10-week composting of poultry manure spiked with enrofloxacin, doxycycline, and ciprofloxacin was performed.
Jan 14, 2022 · Composting is an important technology used to treat and convert organic waste into value-added products. Recently, several studies have been done to investigate the effects of microbial supplementation on the composting of agro-industrial waste. According to these studies, microbial inoculation is considered to be one of the suitable for enhancing the biotransformation of organic
Apr 16, 2019 · In this study, we explored the corrosion behaviors of four common materials (commercially pure Ti, cp-Ti; Sandblasting and acid etching-modified Ti, Ti-SLA; nanowires-modified Ti, Ti-NW; and zinc-containing nanowires-modified Ti, Ti-NW-Zn) with excellent biocompatibilities and osteogenic capacities under the macrophages induced-oxidizing microen
Feb 17, 2020 · Clearly, the enrichment in ARGs without composting was much higher than that with composting, which may be due to the many antibiotic residues and ARGs in poultry manure, as poultry manures are regarded as reservoirs of ARGs [39,55,65]. Of course, the amount of antibiotics added to the feed used in different poultry farms is different, and the
Sep 15, 2020 · We sampled water and sediment from 15 streams draining agricultural watersheds with contrasting levels of concentrated poultry operations (Fig. 1).The watersheds, all on the Delmarva Peninsula, ranged from 0.36 to 18.18 km 2 in area (averaging 7.48 km 2), with 30%–94% cropland (Table 1), mostly used as corn-soybean rotations receiving fertilizer applications.
However, co-composting dead birds with poultry litter (Cummins et al. 1992), an acceptable and desirable disposal method that pro- duces a material amenable to land application, has become popular. Land application offers the best solution to manage- ment of the enormous amounts of manures generated on U.S. poultry farms each year.
Sep 1, 2022 · An innovative biodrying-enhanced composting (BEC) system that applies biodrying to composting process as its start-up stage was developed to rapidly process kitchen waste (KW) into highly
Apr 19, 2020 · We make a wall of manure from the deep bedding of our pigs, sheep and chicken houses and then daily add inputs for the compost such as food scraps, weeds, wood chips, old straw, hay, charcoal, sprouted seeds, greywater system cleanouts and anything biodegradable that we come across such as kombucha scobies and leftover whey from making cheese.
Dec 2, 2012 · The high protein bugs and beneficial microbes are a favorite “snack”, as well as, the weed seeds, food scraps, and any edible green plant tossed into the compost pile. This free food not only improves the quality of the eggs, but it also reduces the amount of feed you have to buy.
May 1, 2020 · However, higher organic nitrogen ammonification rate was observed at the thermophilic stage during poultry litter composting, because lignite added in the composting could capture the NH 4 + from
May 9, 2022 · Kate Martignier May 9, 2022 4 7 minutes read An earth floor, deep-litter system has big benefits for the health and well-being of chickens, and it’s also the easiest way I know to build an ongoing compost creation system in which most of the work is done for you.
