Comparison of pedotransfer functions to estimate the van Genuchten parameters from soil survey information

The aim of our research is to compare the reliability of the methods estimating the parameters of the water holding capacity function (VKF) with the data content of our transparent maps and to examine their further development in the Hungarian Detailed Soil Physics and Hydrology Database (MARTHA). have been used (Bakacsi et al., 2012). They estimated the FAO (1995) physical diversity category of a given soil based on the hygroscopicity (hy) of the soil. On the basis of the pedotransfer functions of Wösten et al. We examined the relationship between hy and the five-category FAO physical variety in the MARTHA database
