Short summary
This study evaluated the sensitivity of silicate mineral dissolution rates to intrinsic and extrinsic factors using a soil evolution model, SoilGen2.25. Modelling results showed a dominant role of pH and a direct effect of soil texture on dissolution rates. Clay migration and plant nutrient recycling influenced the pH and thus the dissolution rates. These results demonstrate the need to couple different soil processes in order to explain differences between lab and field dissolution rates.
