“…Riverine hydro-chemical composition, such as the ratio of HCO − 3 to Ca 2+ + Mg 2+ , is usually employed as an indicator to estimate the CO 2 consumption by natural carbonate weathering on the regional/global scale (Hagedorn and Cartwright, 2009;Li et al, 2009). However, fluvial alkalinity may also be produced by other processes including the reaction between carbonates and protons derived from (i) the nitrification of N fertilizer (Barnes and Raymond, 2009;Gandois et al, 2011;Hamilton et al, 2007;Oh and Raymond, 2006;Perrin et al, 2008;Pierson-wickmann et al, 2009;Semhi and Suchet, 2000;Song et al, 2017aSong et al, , 2011West and McBride, 2005); (ii) sulfuric acid forming in the oxidation of reduced sulfuric minerals (mainly pyrite, FeS 2 ) (Lerman and Wu, 2006;Lerman et al, 2007;Li et al, 2011Li et al, , 2008; (iii) organic acid secreted by microorganisms (Lian et al, 2008); and (iv) acidic soil (such as red soil and yellow soil) (Song et al, 2014(Song et al, , 2017b. Given that atmospheric CO 2 is not a unique weathering agent, differentiating between the agents of carbonate weathering is important for the accurate budgeting of net CO 2 consumption by carbonate weathering, especially in agricultural areas where mineral fertilizers are used.…”

“…The increasing consumption of mineral fertilizers is a significant disturbance factor in carbonate weathering and the carbon cycle. Several studies have shown that nitrogen fertilizer additions increased weathering rates and also increased the total export of DIC (dissolved inorganic carbon) from agricultural watersheds (Barnes and Raymond, 2009;Gandois et al, 2011;Hamilton et al, 2007;Oh and Raymond, 2006;Perrin et al, 2008;Pierson-wickmann et al, 2009;Probst, 1986;Semhi and Suchet, 2000;West and McBride, 2005). According to an estimate by Semhi et al (2000), the contribution of N fertilizers to carbonate dissolution was 30 and 12-26 % in two small agricultural carbonate basins in southwestern France: the Girou and the Gers, respectively (tributaries of the Garonne River).…”

“…In the Garonne River basin, which is a large basin (52 000 km 2 ), this contribution was estimated to be 6 % by Semhi et al (2000). Perrin et al (2008) estimated that the contribution of N fertilizer (usually in the form of NH 4 NO 3 ) represents up to 5.7-13.4 and 1.6-3.8 % of the carbonate dissolution in France and across the world, respectively.…”

Abstract. Carbonate weathering, as a significant vector for the movement of carbon both between and within ecosystems, is strongly influenced by agricultural fertilization, since the addition of fertilizers tends to change the chemical characteristics of soil such as the pH. Different fertilizers may exert a different impact on carbonate weathering, but these discrepancies are as yet not well-known. In this study, a field column experiment was conducted to explore the response of carbonate weathering to the addition of different fertilizers. We compared 11 different treatments, including a control treatment, using three replicates per treatment. Carbonate weathering was assessed by measuring the weight loss of limestone and dolostone tablets buried at the bottom of soil-filled columns. The results show that the addition of urea, NH 4 NO 3 , NH 4 HCO 3 , NH 4 Cl and (NH 4 ) 2 CO 3 distinctly increased carbonate weathering, which was attributed to the nitrification of NH + 4 . The addition of Ca 3 (PO 4 ) 2 , Ca-Mg-P and K 2 CO 3 induced carbonate precipitation due to the common ion effect. The addition of (NH 4 ) 3 PO 4 and NaNO 3 had a relatively small impact on carbonate weathering in comparison to those five NH 4 -based fertilizers above. The results of NaNO 3 treatment raise a new question: the negligible impact of nitrate on carbonate weathering may result in an overestimation of the impact of N fertilizer on CO 2 consumption by carbonate weathering on the regional/global scale if the effects of NO 3 and NH 4 are not distinguished.

Chemical weathering and associated nutrient release act as a control on atmospheric carbon dioxide (CO 2 ) concentration. To globally quantify the contribution of chemical weathering and associated phosphorus (P) release on the historical trend in terrestrial carbon uptake, we applied a weathering model under climate reconstructions from four Earth System Models. In these simulations, CO 2 consumption and P release increased from 1850 to 2005 by 11 ± 3% and 12 ± 4%, respectively. Thereby the intensification of weathering due to climate change could have contributed to a small extent to the trend in terrestrial carbon uptake since the pre-Industrial Period. Using a back of the envelope calculation, we found a feedback strength of CO 2 consumption and P release of −0.02 ± 0.01 W m −2 K −1 and −0.02 ± 0.01 W mrespectively. Although being one magnitude smaller than the carbon cycle feedback, the weathering feedbacks are comparable in strength to small second-order feedbacks such as methane, fire, or ozone.

Terrestrial carbon export via inland aquatic systems is a key process in the global carbon cycle. It includes loss of carbon to the atmosphere via outgassing from rivers, lakes, or reservoirs and carbon fixation in the water column as well as in sediments. This review focuses on headwater streams that are important because their stream biogeochemistry directly reflects carbon input from soils and groundwaters. Major drivers of carbon dioxide partial pressures (pCO2) in streams and mechanisms of terrestrial dissolved inorganic, organic and particulate organic carbon (DIC, DOC, and POC) influxes are summarized in this work. Our analysis indicates that the global river average pCO2 of 3100 ppmV is more often exceeded by contributions from small streams when compared to rivers with larger catchments (> 500 km2). Because of their large proportion in global river networks (> 96% of the total number of streams), headwaters contribute large—but still poorly quantified—amounts of CO2 to the atmosphere. Conservative estimates imply that globally 36% (i.e., 0.93 Pg C yr−1) of total CO2 outgassing from rivers and streams originate from headwaters. We also discuss challenges in determination of CO2 sources, concentrations, and fluxes. To overcome uncertainties of CO2 sources and its outgassing from headwater streams on the global scale, new investigations are needed that should include groundwater data. Such studies would also benefit from applications of integral CO2 outgassing isotope approaches and multiscale geophysical imaging techniques.
