Purpose: The information on the effects of ZnONPs on soil biological processes and the resulting changes of ecosystem function is limited in wheat straw return agricultural soil. This study investigated the effects of ZnONPs on soil heterotrophic respiration and biochemical properties in wheat straw return farmland soil. Materials and methods: An 84-day microcosm incubation experiment was implemented after the exposure of different doses of ZnONPs (0, 100, and 500 mg kg−1 dry soil) in a greenhouse under the temperature of 25 ± 3 °C. Soil heterotrophic respiration and soil enzyme activities were detected. Microbial community composition and diversity were analyzed by Illumina MiSeq platform. ..View full abstract
