Reviewers comment Our reply RC1: Comments 62: How does this older Gaillardet number compare to those more recently produced by co-author Hartmann's papers and Moon et al. (2014)? C1 BGD Interactive comment Printer-friendly version Discussion paper I would consider citing all of these sources and giving a range of the CO2 consumption rate by silicate weathering is In line 67 and 68 we gave the range and considered the suggested authors. RC1: 71-76: Work by Porder and Hilley, as well as Waldbauer and Chamberlain (2005) should be cited in this paragraph or previously The work of Porder and Hilley (2011) is cited in line 80, and Waldbauer and Chamberlain (2005) is cited in line 64. RC1: 97: Have others done this type of analysis or suggested this since von Liebig and Playfair (1843)? We rephrased the sentence. According to Liebig's Law of the minimum(von Liebig and Playfair, 1843), biomass productivity will be limited by the scarcest nutrient in the soil. This law is widely applied to biological populations and in many ecosystem models. The new sentence is in line 103 to 106. RC1: 108: What about changes in precipitation and runoff? The weathering rates of minerals are controlled by the following mechanisms: (i) soil pH (
