Evaluation of Pedotransfer Functions for Predicting the Soil Moisture Retention Curve

Abstract: The soil moisture retention curve (MRC) is time consuming and expensive to measure directly. Several attempts have been made to establish a relation between readily available soil properties, like particle‐size distribution, organic matter content, and bulk density, and the soil moisture retention curve. Those relationships are referred to as pedotransfer functions (PTFs). The objective of this study was to evaluate some PTFs with respect to their accuracy in predicting the soil moisture retention curve. Five … Show more

“…Comparison of PTFs for water content estimation shows poor to good prediction accuracy depending on calculation method and on the location and characteristics of soil samples used for their calibration (Cornelis et al, 2001;Wagner et al, 2001;Givi et al, 2004). Comparison between continuous and class PTFs shows contrasting results, some studies highlighting lower uncertainty with continuous PTFs (Van Alphen et al, 2001), others pointing out that the choice between class and continuous PTFs can be unclear when calculating soil functional characteristics (Al Majou et al, 2007;Rubio et al, 2008).…”

“…Érdemes ezért azokat rendszerezve áttekinteni, ahogy azt a külföldi szakirodalmakban -különböző szempontok szerint -már többen megtették (CORNELIS et al, 2001;WÖSTEN et al, 2001;MCBRATNEY et al, 2002;NEMES et al, 2003;PACHEPSKY & RAWLS, 2004). A becslő módszerek áttekintéséhez az említett szakirodalmakra is támaszkodtam.…”

“…In contrast, measurement of the K (h) curve and water retention curve (WRC) of soils is expensive, time consuming, and labor intensive; and that is why the use of pedotransfer functions (PTF -models that predict these curves from more available data such as particle size distribution, organic matter (OM) content, etc.) has become popular (Cornelis et al, 2001;Schaap et al, 2001;Soracco et al, 2010a). Due to the importance of the WRC and K (h) curve for many processes, it is important to evaluate the efficiency of a PTF that is available, easy to use, and created through the use of a wide database.…”
