Impact of grapevine biochar on some hydro-physical characteristics of silt loam soil – laboratory measurements

Year, pages: 2019, 166 - 171

This study is focused on some hydro-physical characteristics of silt loam soil and their changes after biochar amendment. The used biochar was produced from wooden parts of grapevine (Vitis) in UNIPYR reactor in AgroBioTech Research Center in Nitra, Slovakia. There were established 4 sets in laboratory: pure soil and soil-biochar mixtures with 20, 40 and 80 t ha-1 biochar amendment. Our results confirmed more scientific studies that adding biochar into the soil decreased soil bulk density, particle density and increased porosity. Saturated hydraulic conductivity increased only for higher biochar concentrations in our research. Based on our measurements the optimal amount of grapevine biochar for improving hydro-physical characteristics of silt loam soil was 40 t ha-1.
