Impacts of soil type on the temporal dynamics of antibiotic resistance gene profiles following application of composted manure.

Farmland application of composted manure is associated with a risk of dissemination of antibiotic resistance genes (ARGs) in agricultural soils. However, the impact of soil type on the temporal dynamics of ARGs in agricultural soil remains largely unclear. The aims of this study were to study the persistence of composted manure-derived ARGs in six soil types representative for Chinese agriculture and to explore the underlying environmental drivers of soil ARG profiles in a controlled greenhouse experiment.
