The specific surface area of biochars ranged from 96.06–110.83 m2 g^–1. Hierarchical analyses of the chemical compositions of feedstocks and biochars enabled grouping of the materials respectively into four and five distinguished clusters. Three principal components (PC) explained 86.8% and 83.3% of the variances in the feedstocks and biochars, respectively. The PC1 represented the content of the major nutrients (N, P and K), whereas PC2 and PC3 represented other nutrients (secondary and micronutrients) contents and physicochemical properties (pH and EC). The results of this study suggested that biochars produced from different manures and biosolids may potentially be a source of soil nutrients and trace elements. In addition, different biochars may be applied to different nutrient-deficient soils to avoid plausible nutrient and potentially toxic element contamination.]]> Wed 07 Feb 2024 14:49:22 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:37252 Tue 17 Nov 2020 16:34:38 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:46441 Thu 24 Nov 2022 14:07:36 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:8051 Sat 24 Mar 2018 08:35:03 AEDT ]]>
