Soil acidification refers to the increasing level of hydrogen ions found within the soil profile.
Increasing soil acidity directly affects the chemical nature of the soil, subsequently affecting the biological communities living within the soil and the soils physical structure. The resulting degradation of the acidifying soil leads to issues such as compaction and an increased pressure from weeds and decreased productivity.
Acidic soils commonly occur throughout the higher rainfall zones of the state however are becoming increasingly common in the Murray Mallee. Soil acidification in lower rainfall zones is often linked with continuous cropping systems and can lead to a decreased production of cropping and pasture species.
