dc.descriptionThis study was conducted in the districts of Rusizi, Korongi and Musanze districts, Rwanda in areas where travertine is found. The objective of the study was to characterize the chemical compositions of travertine for use in amending soil acidity for crop production. Thirty two samples of travertine from different deposits at Mashyuza (Rusizi), Gishita (Karongi) and Mpenge and Rwaza (Musanze) were analysed to establish their CaO and MgO contents. Percentages by weight of CaO and MgO in samples were determined using X-ray fluorescence. Results revealed that travertine from Mashyuza and Rwaza has the highest CaO wt% content followed by Gishyita. Mpenge deposits had the lowest content CaO% . There was no significant difference among sites for MgO contin travertine. The tratio of CaO:MgO in Mpenge, Mashyuza and Gishita was within a range required to prevent deficiency of Ca and Mg in acid soils where maize and beans are grown.
