Abstract
Soil pH is commonly measured in water pH(H2O) or pH(KCl). The relationship between pH(H2O) and pH(KCl) across all Bulgarian soils were investigated and results examining the effect of soil type on the relationship were presented. Several functions were used to estimate dependence between the two measures. For all soils and depths, a linear regression accounted for 95.32% of the variation, which predicts pH(KCl) very well. From the analysis of data follows that they were differentiated into three clusters.Keywords
