<p>Emerging research findings suggest that widespread adoption of enhanced rock weathering (ERW) in the field is a promising approach to reduce greenhouse gas emissions and promote plant growth. However, the obstacles to the field-scale application of ERW need to be surmounted first, due to the release of toxic trace elements during wollastonite weathering. Here, we explored crop yield, nutrient uptake, and potentially toxic trace elements enrichment in response to wollastonite applications (0, 2.5, 5, and 10 t ha^–1) with a randomized block design in a typical soybean growing field in northeastern China. We found that 10 t ha^–1 wollastonite application provided the best agronomic benefit, while it did not significantly increase potentially toxic micronutrients in the plants and soil. Specifically, compared with no wollastonite, 10 t ha^–1 wollastonite application increased soybean yield and shoot biomass by 41.2% and 19.3%, respectively. The content of grain protein, nitrogen (N), carbon (C), and calcium (Ca) under 10 t ha^–1 wollastonite application was increased by 11.9%, 8.6%, 1.4%, and 3.5%, respectively, compared to no wollastonite. In addition, wollastonite application reduced copper (Cu) content in the seed and shoot by 10.4–15.9% and 9.0–16.3%, respectively, compared with no wollastonite. Wollastonite application also increased the soil pH and NH₄⁺-N content, and reduced the content of NO₃^–-N and chromium (Cr). Yield and shoot biomass tended to increase with higher wollastonite rates, while the risks of Cr uptake by the seed, and soil nickel (Ni) and arsenic (As) enrichment were significantly increased. Altogether, our results provide a systematic assessment of the effects of using wollastonite as a soil amendment on crop-soil nutrient content and potential toxic element enrichment in the first year. These findings help dispel short-term concerns and provide practical guidance for large-scale field application of wollastonite.</p>
