Uncertainty analysis for spatial prediction of soil saturated hydraulic conductivity
Shui kexue jinzhan, 2012 Pedotransfer functions are commonly used to predict soil hydraulic characteristics.However,the analysis of prediction uncertainty is often ignored by researchers.In an attempt to reduce the prediction uncertainty and to improve the applicability of ...

Predicting soil organic matter content using soil color at three locations with different land use in Zagreb (Croatia) [PDF]
Journal of Central European Agriculture, 2021 Soil organic matter (SOM) plays a key role in ecosystems. Reduction of its content due to land-use changes has a negative impact on the soil, but also on the wider environment. Accordingly, SOM content is routinely analyzed in the laboratory.

Anais da Academia Brasileira de Ciências, 2021 Agriculture needs methodologies that assist in the determination of soil attributes and variability mapping attributes with greater levels of detail. Therefore, the objective of this research was to evaluate magnetic susceptibility as auxiliary variable ...

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2015 Soil is a huge reservoir of water used by plants in periods without precipitation and significantly affects the hydrological balance of any territory. To evaluate the hydrological balance of any piece of the land given, it is therefore necessary to carry

Deriving regional pedotransfer functions to estimate soil bulk density in Austria
Die Bodenkultur, 2021 Soil bulk density is a required variable for quantifying stocks of elements in soils and is therefore instrumental for the evaluation of land-use related climate change mitigation measures. Our motivation was to derive a set of pedotransfer functions for

Retention curves of soil from the liz experimental catchment obtained by three methods
Soil and Water Research, 2009 The retention curves were measured in the soil from the Liz experimental catchment (Šumava). The sand table and pressure extractor methods were used to obtain a 13-point retention curve for undisturbed soil samples taken from 6 depths. The data points of

Development of pedotransfer functions for Brazilian soils
Conjecturas, 2022 Pedotransfer Functions (PFT’s) have several applications in the agri-environmental field, hydrodynamically characterizing soils in a less costly and more accessible way. The work proposed to develop equations that characterized Brazilian tropical soils through numerical validations available in the HYBRAS database, comparing them with others available ...

New generation of hydraulic pedotransfer functions for Europe [PDF]
European Journal of Soil Science, 2014 Summary A range of continental‐scale soil datasets exists in Europe with different spatial representation and based on different principles. We developed comprehensive pedotransfer functions ( PTF s) for applications principally on spatial datasets with continental coverage.

Functional Evaluation of Pedotransfer Functions for the Estimation of Soil Hydraulic Properties [PDF]
Soil Science Society of America Journal, 1992 Abstract Pedotransfer functions (PTFs) are often used for estimating hydraulic properties such as the moisture retention characteristic and the pressure head‐hydraulic conductivity relationship. Both properties are essential for the description of water and solute movement in unsaturated soils.
