Nitrogen enrichment suppresses revegetated shrub growth under increased precipitation via herb-induced topsoil water limitation in a desert ecosystem in northern China

Background and aims Revegetated woody plant communities are widely distributed in degraded drylands, and they are expected to be intrinsically sensitive to precipitation change and nitrogen enrichment. However, the interactive effects of precipitation and nitrogen on them remain largely unknown. This study aimed to examine how revegetated plant community responds to an increase in precipitation and nitrogen enrichment.
