Reducing risks of antibiotics to crop production requires land system intensification within thresholds

F. Zhao, L. Yang, et al.

This study by Fangkai Zhao, Lei Yang, Haw Yen, Qingyu Feng, Min Li, and Liding Chen unveils how land system intensification in China enhances crop production yet poses significant soil antibiotic pollution risks. When the pollution risk quotient exceeds a certain threshold, crop yields could drastically drop, highlighting the need for sustainable land management practices.

Abstract

Land system intensification has substantially enhanced crop production but also created soil antibiotic pollution, undermining crop production. This study projected soil antibiotic pollution risks to crop production in China and linked them to land system intensification. Projections suggest crop production will substantially decrease when the soil antibiotic pollution risk quotient exceeds 8.30–9.98. Land systems explain most variability in antibiotic pollution risks (21–66%). The study indicates that land system intensification below minimum thresholds at multiple scales is required for acceptable antibiotic pollution risks related to crop yield reduction.
