The authors explore the response of crop productivity and soil inorganic carbon to ERW in farmland and analyze the contribution and prioritization of environment drivers for the above change. A series of monitoring trials were established in a multi-agroclimatic region in central China from 2019 to 2021. Firstly, crop productivity and SIC change mediated by ERW were evaluated by applying 10 kg m−2 mixed rock powder in field trials. Secondly, the random forest and correlation network analysis were used to quantify the influence of climate, soil, and management drivers on yield and SIC change. Finally, the carbon footprint of silicate rock powder was calculated by life cycle analysis.
