Hydrological, ecohydrological, and terrestrial biosphere models depend on pedotransfer functions for computing soil hydraulic parameters based easily measurable variables, such as textural physical properties. Several have been derived in the last few decades, providing divergent estimates of parameters. In this study, we quantify how uncertainties embedded using different propagate to ecosyste...

Mollisols of Santa Fe have different tilth and load support capacity. Despite the importance of these attributes to achieve a sustainable crop production, few information is available. The objectives of this study are i) to assess soil physical indicators related to plant growth and to soil mechanical behavior; and ii) to establish relationships to estimate the impact of soil loading on the soi...

The paper aim is to propose a new regression model for relating soil variables of difficult or complex measurement with other variables easier to measure, in order to predict the first one based on data about the last ones. The measurements are taken along soil lines called transects. The study of these relations (pedotransfer functions) presents the complexity of simultaneous presence of 3 ele...
