Application of the 2% (w/w) FA-BC also significantly reduced the leaching of total P (81.3%) from the soil column, while maintained an appropriate level of bioavailable P in the soil for sustaining plant growth. The chemical sequestration test and in-situ P k-edge XANES analyses of the FA-BC incubated soils revealed that the labile Ca-P fractions were transformed into stabilized Fe/Al-P complexes. The increased soil pH, a higher degree of soil P saturation, and intensive interaction between P and Fe/Al (hydr)oxides also contributed to the superior ability of the FA-BC amended soils towards P retention. This study provided field-relevant implications for the design and application of engineered biochar for green and sustainable improvement of agricultural soils.]]> Tue 13 Jul 2021 11:50:38 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:54257 Tue 13 Feb 2024 13:32:40 AEDT ]]>
