“…(11). This process of carbonate weathering by protons released from nitrification has been demonstrated by many studies, from the laboratory to the field (Barnes and Raymond, 2009;Bertrand et al, 2007;Biasi et al, 2008;Errin et al, 2006;Gandois et al, 2011;Hamilton et al, 2007;Oh and Raymond, 2006;Perrin et al, 2008;Semhi and Suchet, 2000;Song et al, 2017aSong et al, , 2011West and McBride, 2005). We have noted that the R w values in NH 4 HCO 3 and (NH 4 ) 2 CO 3 treatments are less than half those in the urea treatment despite adding the same amount of fertilizerderived NH 4 (approximately 1.07 mole).…”

“…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).…”

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.

Vpliv kmetijske dejavnosti in kislih usedlin iz zraka na preperevanje karbonatov na majhnem kraškem kmetijskem območju na jugozahodu Kitajske Da bi določili izvor in tok DIC (raztopljen anorganski ogljik) smo vrednotili učinek uporabe dušikovih gnojil in kislih usedlin na preperevanje karbonatov. Pri tem smo se poslužili hidrokemičnih postopkov in analize δ 13 C DIC podzemne vode v kraškem zaledju reke Quinmugan (QURS), ki je del manjšega kmetijskega območja na jugozahodu Kitajske. Rezultati so pokazali naslednje: (1) Izmerjene so bile opazne časovne spremembe v koncentraciji glavnih elementov in δ 13 C DIC v podzemni vodi v različnih mesecih; to je še posebej očitno v deževnem obdobju in času gnojenja, ko so bile zabeležene izrazito povečane koncentracije DIC, Ca ) and HCO 3 − of groundwater in different months averaged 11.1 % and 6.7 %, respectively, and the contributions of carbonate dissolution by sulphuric acid originated from the atmospheric acid deposition to total concentrations of (Ca

Chemical weathering and the role of sulfuric and nitric acids in carbonate weathering: Isotopes (¹³C, ¹⁵N, ³⁴S, and ¹⁸O) and chemical constraints

Multiple isotopes (13C‐DIC, 34S and 18O‐SO42−, 15N and 18O‐NO3−) and water chemistry were used to evaluate weathering rates and associated CO2 consumption by carbonic acid and strong acids (H2SO4 and HNO3) in a typical karst watershed (Wujiang River, Southwest China). The dual sulfate isotopes indicate that sulfate is mainly derived from sulfide oxidation in coal stratum and sulfide‐containing minerals, and dual nitrate isotopes indicate that nitrate is mainly derived from soil N and nitrification. The correlation between isotopic compositions and water chemistry suggests that sulfuric and nitric acids, in addition to carbonic acid, are involved in carbonate weathering. The silicate and carbonate weathering rates are 7.2 t km−2 yr−1 and 76 t km−2 yr−1, respectively. In comparison with carbonate weathering rates (43 t km−2 yr−1) by carbonic acid alone, the subsequent increase in rates indicates significant enhancement of weathering when combined with sulfuric and nitric acids. Therefore, the role of sulfuric and nitric acids in the rock weathering should be considered in the global carbon cycle.
