The Testing soil nutrients section of the Soil Quality Knowledge Base emphasises that soil testing is a valuable tool for detecting conditions, such as nutrient deficiencies or toxicities, that may restrict plant growth. The webpage provides detailed information and infographics on essential nutrients, including nitrogen, phosphorus, potassium, sulfur, and trace elements, and offers guidance on selecting appropriate laboratories for soil analysis. Additionally, it discusses the interpretation of test results, and how to develop a fertiliser recommendation model based on soil test calibration curves and critical soil test levels. There is also a link to a nutrient calculator for rainfall pastures. While the content focuses on Western Australia, 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
