Sažetak
The data of 45 soil profiles from a 16 × 16 km grid across Slo­venia was analysed to develop a local pedotransfer function (PTF) for bulk den­sity (.b) estimation. In total, 106 soil horizons were considered. Concentration of organic carbon (OC) was found to be well correlated (r = -0.861, p < 0.001) with .b. Two separate line segments were fitted to the data, which was partitio­ned into two intervals, based on OC content (below 36.0 g/kg and above 36.0 g/kg). Nearly 80 % of the variability in .b is explained with segmented re­gression. The local PTF was compared with published PTFs and four valida­tions indices (MPE, SDPE, RMSPE and R2) confirmed the highest prediction quality of the local PTF. The differences of carbon stock (Cpool) estimation, based on usage of different PTFs could be higher than 160 t OC per hectare. Predic­tion of carbon stocks could be substantially improved by calibration of the mo­dels coefficients with data stratified according to each unique soil type.
