This paper investigates whether selected properties of<br \/>\nextensively weathered, low&nbsp;fertility soils&nbsp;can be predicted using high-resolution reflectance<br \/>\nspectra over the range 400\u20132500&nbsp;nm. Clay content, carbonate concentration,&nbsp;organic<br \/>\ncarbon&nbsp;content and&nbsp;iron oxide&nbsp;content were analysed for 300 soil samples collected from the<br \/>\nJamestown, Belalie district, South Australia. The paper also examines the efficacy of this soil<br \/>\nanalysis methodology to supplement or replace traditional soil sampling in soil survey to<br \/>\nincrease sampling density and improve the spatial resolution of soil maps.<br \/>\nReflectance spectra were obtained from air-dried samples under controlled laboratory<br \/>\nconditions using an ASD FieldSpec Pro&nbsp;spectroradiometer. Partial least squares regression was<\/p>\n<p>used to examine relationships between&nbsp;soil mineralogy, clay content and organic carbon and the<br \/>\nreflectance spectra and identify the wavelengths contributing to prediction of these soil<br \/>\nproperties. Results show that it is possible to predict clay content, soil organic carbon, iron oxide<br \/>\ncontent and carbonate content. Cross-validation&nbsp;R 2 &nbsp;values for all analyses were above 0.5 and the<br \/>\nresidual prediction difference (RPD) was acceptable for all soil properties. Carbonate and clay<br \/>\ncontent were more accurately predicted than iron oxide and organic carbon. All samples were<br \/>\ncollected from the same geographical area such that they represented physical properties over a<br \/>\nnaturally occurring range and provide a prediction that could be related to subsequent image<br \/>\nanalysis or be used to carry out local scale soil survey. A rapid and reliable form of soil mapping<br \/>\ncould be developed from this methodology.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>It is becoming increasingly important to improve spatial resolutions of soil maps as a fundamental information layer for studying ecological processes and to tackle&nbsp;land degradation.
