What is it?
Acid Sulphate Soil (ASS) is the common name given to soil and sediments containing iron sulphides. When drainage and disturbance expose this soil to air, they produce sulphuric acid, often containing toxic quantities of iron, aluminium and heavy metals.

This can result in the acidification of soil, sediment, rock, and water having and extreme negative impact on aquatic communities, agricultural practices, and engineering works. ASS can affect land use and development, and must be considered and managed in the planning stages, before land has been cleared or drained, and before construction can begin.

What is its impact?
Acid sulphate soil, if left untreated, will cause acid water run off which contributes to blue green algae. Numerous negative impacts occur from ASS, across many different industries. ASS affects soil quality, aquatic habitats, groundwater quality, drainage systems and many more factors in both the civil and agricultural industries.

Agricultural Lime

What is it?
Agricultural Lime is a soil additive made from pulverised limestone. Its main use in civil and agricultural industries is to neutralise acid sulphate soils. This gives ASS higher productivity, and makes it less hazardous to plant, people and construction works.

What does it do?
When Aglime is incorporated into ASS, the levels of calcium and magnesium are raised, thus neutralising the soil, and making it more usable.
