|  Trees, Acid Sulfate Soils (ASS) and microbial migration
Acid sulfate soil (ASS) is the common name given to soils and sediments containing iron sulfides, the most common being pyrite. When exposed to air due to drainage or disturbance, these soils produce sulfuric acid, often releasing toxic quantities of iron, aluminium and heavy metals (QLD state gov classification). Which trees do you think would perform better in ASS? Tuckeroo Ivory Curl Crows Ash |

| Re: Trees, Acid Sulfate Soils (ASS) and microbial migration
Big open question Depends on for what purpose and where? Residential, commercial, farming or community and therefore is soil amelioration viable / possible Had some ‘success’ on an acid, salty project through soil testing, mulching, soil amelioration and profiling but it can tend to be ongoing therefore scope of project is important |

crusin_long Sorry I should have defined the growing environment as an urban forest with amenity and recreational value. |
