“…Wollastonite weathering under laboratory conditions is well documented (Huijgen et al, 2006), however, the only experimental data under northern hemisphere cropped conditions is available in our previous pot study (Haque et al, 2019c), and in our recently published field study (Haque et al, 2020). In the latter, we analyzed the soil from two commercial fields in Ontario, where wollastonite was being used as a soil mineralizer, to identify evidence of soil inorganic carbon accumulation (as pedogenic carbonates), and also conducted a field experiment to grow soybean under three different dosages of wollastonite.…”

“…Hence, application of wollastonite in agricultural fields is a known practice; however, using wollastonite for sequestering carbon via terrestrial enhanced weathering is not well reported. In our recent study (Haque et al, 2020), a field-scale wollastonite amendment experiment was conducted at a commercial soybean farm, for verification of CO 2 sequestration and effects on crop yield at field conditions. Soils at two additional farms (leafy vegetables, and potato) that had voluntarily used wollastonite amendment for one or more crop cycles were also studied for evidence of CO 2 sequestration.…”

“…Room temperature Mössbauer spectra were collected at the Department of Chemical Science (University of Padova), by means of a conventional constant acceleration spectrometer mounting an 57 Co source, nominal strength 1850 MBq. The sample was prepared by mixing ≈ 70 mg of wollastonite, gently crushed in acetone, with Vaseline.…”

“…Due to its chemical stability and thermal resistivity, fibrous wollastonite is used as substitute for asbestos in the manufacture of building material [53]. In addition to its traditional uses, wollastonite has also been used as a bioactive material for biomedical applications [54], soil conditioner for agricultural purposes [55], pollutant absorber for environmental applications [56] and raw material for carbonation reactors used for CO 2 sequestration [57]. The main wollastonite mines are located in China, Finland, India, Mexico, and the USA [46].…”
