These mineral concentrations together with pH and soil organic matter data were used to train Cubist models for the prediction of log(Na aqr), log(Mg aqr), log(K aqr), and log(Ca aqr), yielding concordance correlation coefficients of 0.77, 0.87, 0.78 and 0.71, respectively when assessed by cross validation. Aqua regia, also known as “royal water,” was named during the Middle Ages because it was a special liquid that could dissolve even noble metals (like gold and platinum), which did not react well with other solutions.
