The transfer of antibiotic resistance genes (ARGs) from soils to vegetables negatively impacts human health. This study explored the effects high-dose (18.73 t/ha) application traditional compost (TC) and composts produced through co-composting materials with large-sized (5–10 mm) biochar-amended (LBTC) or small-sized (< 0.074 (SBTC) on distribution ARGs in a soil–cucumber system were explored. Results indicated that SBTC group had highest soil nitrogen, phosphorus, potassium contents, followed by LBTC, TC, control treatment groups. These findings aligned quality weight harvested cucumbers. Bacterial community diversity decreased compost-fertilized soils. Compared their preexperimental values soils, total absolute abundances mobile genetic elements (MGEs) increased 23.88 6.66 times, respectively, group; 5.59 5.23 TC 5.50 1.81 LBTC 5.49 0.47 group. those group, abundance ermB , ermT gyrA qnrS tetC intI1 6–100% Compost significantly ARG cucumbers; most significant effect reduced number host bacteria at phylum level four three.

Optimization and Experiment of Livestock and Poultry Manure Composting Equipment with Vented Heating

Sustainability, Journal Year: 2023, Volume and Issue: 15(14), P. 11353 - 11353

Published: July 21, 2023

As livestock and poultry farming expands in China, the generation of fecal waste has significantly increased. Inadequate management can contribute to environmental pollution. This study seeks optimize small-scale composting systems address inefficiencies limited automation traditional equipment. We redesigned mixing blades refined ventilation heating system, establishing an efficient mechanism energy-saving system. A control incorporating Monitor Control Generated System Programmable logic Controller, was developed for real-time monitoring adjustment capabilities, substantially enhancing levels. The optimization proved effective by reducing cycle from 13 days 11.5 days, increasing GI value 83% 89%, lowering humidity 8.9% 8.1%.
