The soil clay mineralogy did not change systematically with depth (0- 10, 10- 20 and 20- 30 cm) and showed large variations spatially. The high proportion of kaolinite was probably due to the removal of 2:1 phyllosilicates by the formation of 1:1 kaolinite through weathering, which also reduced the cation exchange capacity (CEC) and electrical conductivity (EC, soil: water ratio of 1:5) of soils by aging. Soils were classified as silty loam to loam with a low clay size (≤ 2]]> Wed 07 Apr 2021 13:31:51 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:728 Wed 07 Apr 2021 13:31:42 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:480 Wed 07 Apr 2021 13:31:24 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:479 Wed 07 Apr 2021 13:31:24 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:301 Wed 07 Apr 2021 13:31:11 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:182 53 mum) macro-C fraction, and a decrease in exchangeable Ca and Mg was found in the agricultural soils, compared with forest soils. Physically protected C in the <53 μm fraction, as indicated by UV photo-oxidation, was similar among soils. Wet sieving indicated a decline of both C and N concentration in water-stable aggregates and the degree of macro-aggregation under agricultural soils, compared with the forest soils. However, soil structural changes under cropping were mainly related to a decline in the >5 mm sized aggregates, with no deleterious increase in the proportion of 0.10 mm aggregates. Solid state C-13 NMR spectroscopy indicated a decrease in O-alkyl and alkyl C under pasture and cropping compared with forest soils, which was in agreement with the decline in the macro-C fraction. Characterisation of C chemistry following UV photo-oxidation showed that charcoal C (dominant presence of aryl C) accounted for 30% of the total soil organic C, while other functional groups (polysaccharides and alkyl C) were probably protected within micro-aggregates. Based on soil organic C and aggregate stability determinations alone, the implications for soil physical quality, soil loss, and diffuse pollution appear minimal.]]> Wed 07 Apr 2021 13:31:02 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:14318 Thu 25 Nov 2021 11:44:15 AEDT ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:15214 Thu 02 Jun 2022 15:16:59 AEST ]]>
