“…Because of high chemical stability, biochar has a great potential to enhance atmospheric carbon sequestration (Laird et al, 2008;Lehmann et al, 2006). Soil amendments such as biochar, composts or their mixtures can decrease soil bulk density (Abd El-Mageed et al, 2021;Hardie et al, 2014), improve soil structure (Ajayi and Horn, 2016;Juriga et al, 2021), increase soil pH (Horák, 2015) cation exchange capacity (Igaz et al, 2018;Jien and Wang, 2013), soil N availability (Haider et al, 2017;Van Zwieten et al, 2010), organic carbon content (Ajayi and Horn, 2016;Šrank and Šimanský, 2020), soil porosity (Blanco-Canqui, 2017;Githinji, 2014), available water content (Głąb et al, 2016;Ibrahim et al, 2013) and saturated hydraulic conductivity (Jien and Wang, 2013;Toková et al, 2020). Syakila and Kroeze (2011) reported that agricultural N2O emission in 2006 reached 23-31% of the global emissions with the main source being nitrogen fertilizer and manure application to soils.…”
