Title: | Driving factors of soil organic carbon fractions over New South Wales, Australia | Contributor(s): | Gray, Jonathan (author); Karunaratne, Senani (author); Bishop, Thomas (author); Wilson, Brian (author) ; Veeragathipillai, Manoharan (author) | Publication Date: | 2019-11-01 | Early Online Version: | 2019-07-10 | DOI: | 10.1016/j.geoderma.2019.06.032 | Handle Link: | https://hdl.handle.net/1959.11/30608 | Abstract: | We modelled and mapped the distribution of three principal soil organic carbon (SOC) fractions across New South Wales and gained insights into the factors controlling their distribution. Carbon fractions are important for modelling soil carbon dynamics for carbon accounting, and as a potential indicator of soil quality. We considered particulate organic carbon (POC), humic organic carbon (HOC) and resistant organic carbon (ROC), which represent fractions of increasing bio-chemical stability. A dataset of 427 NSW profiles with mid-infrared (MIR) derived carbon fractions and a set of 16 predictor variables were applied. Random Forest and multiple linear regression techniques were applied, for depth intervals to 30 cm. | Publication Type: | Journal Article | Source of Publication: | Geoderma, v.353, p. 213-226 | Publisher: | Elsevier BV | Place of Publication: | Netherlands | ISSN: | 1872-6259 0016-7061 |
