An inter-laboratory study was conducted to determine the variability of three aglime analysis methods. The methods evaluated were; total Ca and Mg analysis, neutralization of 0,5 mol dm-3 HCl and a resin suspension method. It was found that the resin suspension method not only significantly gave the best reproducibility between laboratories, but it proved to be the most discriminatory between samples, as it is sensitive to all aspects involved, such as fineness, chemical purity and other physical properties.
