Soils play a critical role in supporting agricultural production. Subsoils, below 20 cm, underpin fundamental agroecosystem sustainability traits including soil carbon storage, climate regulation and water provision. However, little is known about the ecological stability of subsoils in response to global change.

- Growing evidence shows that using manure with residual antibiotics increases soil antibiotic resistance genes (ARGs), but the impact of long-term antibiotic-free fertilization is not well understood.
- This study found that while long-term fertilization affects the diversity of ARGs minimally, antibiotic-free manure leads to lower increases in ARG abundances compared to chemical fertilizers.
- However, combining antibiotic-free manure with chemical fertilizers resulted in higher nutrient levels and enhanced certain microbial populations, indicating that while antibiotic-free practices help reduce risks, they don’t completely eliminate ARGs, suggesting a need for broader strategies in agriculture to combat antibiotic resistance.
Reducing antibiotic levels in soil ecosystems is vital to curb the dissemination of antimicrobial resistance genes (ARGs) and mitigate global health threats. However, gaps persist in understanding how antibiotic resistome can be suppressed during antibiotic degradation. Herein, we investigate the efficacy of a biochar biofilm incorporating antibiotics-degrading bacterial strain (Arthrobacter sp.

In this study, the paddy fields fertilized with chemical fertilizer, swine compost, and no fertilizer were investigated to assess the transfer of ARGs from soil to rice. Soil and plant samples were collected at day 0, 7, 30 and 79 representing various stages of paddy growth.
