Longâ€term effect of biochar on physical properties of agricultural soils with different textures at preâ€industrial charcoal kiln sites in Wallonia (Belgium)

Besides its carbon (C) sequestration potential, biochar is being promoted as an amendment to improve soil quality. Burying biochar in soils is known to affect soil physical quality in the short-term (<5 years), although the intensity of these effects depends on soil texture and biochar concentration especially. However, the long-term effects of biochar remain largely unknown, yet are important to quantify given biochar's persistency in soils. The objective of this study was therefore to assess the long-term effect of biochar on physical properties as a function of biochar concentration for... Mehr ...
