Dispersion of clay plates by changing soil pH – WA (Video)
This Soil Quality Knowledge Base video uses graphics to explain, at a molecular level, how clay platelets at a neutral pH have negatively charged faces and positive charges edges. The clay platelets stick together. If the pH increases (becomes alkaline) the edge charges become negative and the clay platelets disperse. While the content focuses on Western Australia, the information is applicable to other Australian regions [1:15].#
Audience: RSP, tertiary students, landholders, SFSG, consultants, school students
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
