Pedotransfer functions (PTFs) are physical–mathematical models which allow estimating soil hydraulic properties from soil data. In the absence of direct measurements, they represent a valuable tool for providing agro-ecological models with soil input estimations, whose accuracy is currently a key issue, especially in field- and regional-scale modelling which rely on soil information databases. The class library IRENE_DLL (Integrated Resources for Evaluating Numerical Estimates – Dynamic Link Library) is a repository of statistical methods and procedures designed to properly handle comparisons between model estimates and actual measurements. A distinct feature is the support for developing integrated evaluation indices based on a two-stage, fuzzy-based approach. We implemented this approach into PTFIndicator, a Microsoft Excel application based on IRENE_DLL, to evaluate the performance of PTFs. This paper introduces the overall functioning of the application, and briefly discusses one relevant worked example.
