Abstract
Our results highlight the particularly low soil production rates of flat terrains in temperate climates. Moreover, they provide evidence that the reactions of mineral weathering actually take place in horizons deeper than 1Â m, while a chemical steady state of both concentrations and U-series disequilibria is established in the upper most soil layers, i.e., above â¼70Â cm depth. In such cases, the use of soil surface horizons for determining weathering rates is precluded and illustrates the need to focus instead on the deepest soil horizons.
