The Soil colour section of the Soil Quality Knowledge Base discusses how soil colour serves as an indicator of internal drainage and helps distinguish soil layers. It explains how mineral and organic matter influence soil colour, with iron and aluminium oxides contributing to red, yellow, grey, and bluish-grey hues. For objective assessment, soil colour can be compared to standard Munsell Soil Colour Charts. While the content is written for Western Australian soils, the principles are applicable to other Australian regions. #
This is a carefully curated database of important soil resources. The data base is not exhaustive but rather a library of the resources we believe are the most useful for the audience. Each resource has been added after careful consideration against our selection criteria, including but not limited to its scientific validity, accessibility, and readability. The library generally does not include most academic research papers but may include some open-source papers written in accessible English.

SSA reminds users that these resources are a guide only. Our understanding of soil science is improving continuously so it is important to check the suitability of the information for your purpose with an appropriately qualified professional such as a Registered Soil Professional or a Certified Professional Soil ScientistÂ
