AS 4419:2018 PDF
This Standard provides manufacturers with a set of requirements which will ensure that soils can support plant growth and to give users, such as growers, landscape architects and consumers, assurance of the suitability and quality of soils.
This Standard sets out requirements and methods of test for general purpose soils, top dressing, topsoil and landscaping mixes, for domestic and commercial use, supplied in either bulk or bagged lots.
NOTES:
1 The requirements of this Standard specify soils suitable for the vast majority of plants but do not cover soils for plants with special requirements, cricket pitch soils, other specialist sporting turf soils or fertilizers.
2 All materials need to fully comply with the provisions of the current version of the State guidelines (or national guidelines in the absence of State guidelines) for use in application to land.
3 Requirements for potting mixes are specified in AS 3743.
4 It is often assumed that the darker the soil the better the quality. As this is not always the case, this specification does not specify colour requirements for soils.
5 Guidelines for taking soil samples are given in Appendix A.
6 Information on selection and use of soils is given in Appendix M
