The soil texture representation with the standard texturalfraction triplet sand–silt–clay is commonly used to estimate soilproperties. The objective of this work was to test the hypothesis that otherfraction sizes in the triplets may provide a better representation of soiltexture for estimating some soil parameters. We estimated the cumulativeparticle size distribution and bulk density from an entropy-based representationof the textural triplet with experimental data for 6240 soil samples. The resultssupported the hypothesis. For example, simulated distributions were notsignificantly different from the original ones in 25 and 85 % of cases whenthe sand–silt–clay and very coarse+coarse + medium sand − fine + very finesand − silt+clay were used, respectively. When the same standard andmodified triplets were used to estimate the average bulk density, thecoefficients of determination were 0.001 and 0.967, respectively. Overall,the textural triplet selection appears to be application and data specific.
