Standards

Soil Science Australia is committed to ensuring that the highest standards of work are adhered to. This is the primary reason that our Certified Professional Soil Scientist accreditation exists.

We also serve on various committees that inform the multidisciplinary Standards Australia.

If you are a soil scientist and interested in nominating for one of the many Standards Australia committees, please get in contact. Soil Science Australia regularly nominates individuals and has an internal process for organisational position development and support of individuals acting on behalf of Soil Science Australia.

The Australian Soil and Land Survey Field Handbook revisions and proposed changes

ASLSFH changes discussed and agreed to:

  • Addition of extratidal Flat (ETF) and subtidal flat (SBF)
  • Agreement to add 2 codes in relation to DEM derivation of slope (coarse and fine)
    • Fine DEM: Slope derived from a DEM finer than 10 m resolution, calculated to give the effective slope of the line of steepest descent over interval of 20 m centred on the observation. (e.g. LIDAR, Air Photo-derived).
    • Coarse DEM: Slope derived from a DEM with 10 m to 30 m resolution, calculated to give the effective slope of the line of steepest descent over interval of 20 m centred on the observation site. (e.g. the national 1 second DEM and contour-based DEMs).
  • B horizon definition – amendment to the same definition as per the new edition of the ASC

Proposed changes for consideration include:

  • Revision of microrelief codes and definitions
  • Revision of microrelief codes and definitions
  • A and A2 horizon definition
  • D horizon definition
  • Addition of an M horizon
  • Horizon suffix definitions
  • Permeability and drainage definitions
  • Ash horizons
  • Surface condition definitions
  • Substrate lithology terms

Please contact your relevant representative to submit a proposed change for consideration.

Invitation to review The Australian Soil Classification (ASC)

The Third Edition of the ASC is getting close to completion. There have been substantial changes to the Second Edition, most notably the introduction of a new Soil Order – the Arenosols – to cater for deep sands. This new edition is the collective effort of the ASC Working Group, and many fellow soil scientists, over the last few years.

A pdf of the new edition is available for viewing or download, and comments and suggestions are invited and indeed welcomed by anyone with an interest in this area. Feel free to distribute it as widely as you wish. It is important that we get it right.

Details of the (many) changes in the new edition are provided in the report Preface, and email addresses where comments and suggestions can be sent are listed inside the cover.
Deadline for comments is 29 February 2020.
