This Soil Quality Knowledge Base webpage includes a diagram that shows the differences betwen gravel soils and non-gravel soils. It explains the key differences: high nitrogen mineralisation (breakdown of soil organic matter to plant-available nutrients), waxy coating that repels water, concentration of soil organic matter. These processes require further research. This information was previously published as an ebook, Soil Quality: 9 Gravel soil. While the content is written for Western Australian soils, it may also apply to other southern 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
