Reported methods for determination of carbonate content in sediments can be divided into five types due to the following rationales. First, based on the reaction between carbonate and hydrochloric acid (Lamas et al., 2005), carbonate content can be calculated by determining the consumed HCl through an acid-base titration method (Yang et al., 2016b).
Soil calcium carbonate (CaCO3) content is an important soil property. The prediction of soil CaCO3 content is necessary for the sustainable management of soil fertility. In this work, we attempted to incorporate environmental variables directly and through regression models into the framework of Bayesian maximum entropy (BME) to predict CaCO3 content. …
