Why is the soil in Australia considered old?
Australia’s soils are old. During the last ice age (around 20,000–26,000 years ago) many land masses were covered by ice sheets, which scraped away the soil as they moved over the continents. As the exposed fresh rocks weathered, new and nutrient rich soils were created.
What causes poor soil quality?
A major cause of reduced soil quality is soil erosion, the removal of the topsoil. … Soil erosion by wind pollutes the air and can damage plants through a sandblasting effect. Compaction, accumulation of salts, excess nutrients and chemicals, and toxic chemicals are also significant soil quality concerns.
Why is the soil in Australia so red?

Where is desertification in Australia?
Desertification in some form is estimated to have occurred over about 42% of the 5 million km2 of arid and semiarid lands in Australia. The most common form of desertification is loss of perennial grasses from grasslands, savannas, and open woodlands, often with a replacement by inedible shrubs.
