Biochar presence in soil significantly decreased saturated hydraulic conductivity due to swelling
Original language description
The application of biochar on two contrasting soils was tested in order to assess its effects on soil hydraulic properties (SHP) and study the interaction between water and the biochar surface (e.g., the swelling effect). Two contrasting soil types were enriched with 0, 2 and 5% (wt.) doses of grape stalks biochar in order to prepare soil samples for a 14-days continually saturated laboratory experiment. H2O bonds to the biochar surface were detected using FTIR spectroscopy. Results show that water molecules were bound through polar hydrogen bonds to O-H and C-O-H, and these interactions caused (i) intensive swelling, which decreased the bulk density and enhanced the water holding capacity (up to 5% in the case of sandy loam and 5% biochar dose), and (ii) significantly decreased Ks in both soils (with a maximum difference of 82,6%). The results of this laboratory experiment provide useful information about the significant effect of presented biochar in two contrasting soils, and its applica
