Abstract

The aims of this study were to investigate how management practises and topography influence the variability of key soil properties and to test the efficacy of various analytical techniques for predictive high resolution soil mapping. The AA. sampled soil properties measured in an intensively managed orchard in the Adelaide Hills, South Australia using a stratified sampling design for alleys and tree-lines in order to distinguish potential management effects from effects of natural soil variability. Key soil properties were determined using standard techniques and predictions using mid-infrared partial least-squares (MIR-PLS). Total organic carbon (TOC), electrical conductivity (EC) and coarse fraction were significantly different in tree-line and in alley. The degree of correlation between soil properties and terrain parameters was influenced by the different management regimes
