Soil properties

  • Soil texture

    Soil texture refers to the proportion of sand, silt and clay sized particles that make up the mineral fraction of the soil.

  • Soil structure

    Soil structure refers to the way soil particles group together to form aggregates (or peds).

  • Soil colour

    Colour can be a useful indicator of some general soil properties and processes occurring below the surface.

  • Soil ph

    Soil pH is a measure of the acidity or alkalinity of the soil. Having the correct pH is important for healthy plant growth.

  • Soil carbon

    Soils can store, cycle and emit as gases different forms of carbon, and soil carbon is an indicator of soil health.

  • Soil water

    Water supply through soils is vital for both plants and soil organisms.

  • Soil fertility

    For plants to be healthy, they need a steady supply of nutrients from the soil. A shortage or excess of nutrients can affect plant growth.

  • Soil sodicity

    Sodicity is a natural feature of many Queensland soils. Soils are often considered sodic when the amount of sodium impacts soil structure.
