The cation exchange capacity (CEC) of soil is an important parameter since it is an indicator of the fertility and physicochemical quality of the soil. There are several methods to find and estimate the CEC of soils. This work aims to compare the direct ammonium distillation method and the exchangeable base summation method based on the analysis of 65 samples taken from 0 to 0.20 m depth of soils in the northern and western areas of Honduras. Initially, the analyses of pH, % organic matter, % clay, and exchangeable bases (Ca, Mg, K, and Na) extracted with ammonium acetate at pH 7.00 were carried out. In addition, they were determined by atomic absorption, exchangeable acidity (H and Al), extracted with 1N KCl determined by titration. Subsequently, the CEC was determined by direct method of soil washing and ammonium distillation. The data was subjected to Pearson correlation analysis and ...
