PARIOplus—A reliable method for determining soil texture?

Abstract The new PARIOplus soil texture measuring system, based on the integral suspension pressure method, a modification of the PARIOclassic, is a method in which the suspension pressure curve measured with a high‐precision sensor is adapted to the modelled Stokes' law of sedimentation by means of inverse modelling. In order to validate the method, soil samples were mixed from artificial material to cover the entire grain size triangle. The results were also compared with those of the burette. This study shows that PARIOplus provides reliable and comparable results with R 2 > 0.99 in all texture classes.
