A framework relating soil surface condition to infiltration and sediment and nutrient mobilisation in grazing rangelands of North-eastern Queensland, Australia Site 4 – High Range

Level 1: General Description


This study aims to provide evidence that grazing induces variations in soil surface condition, infiltration and runoff composition. The objective of the study is to develop a framework relating to ground cover and soil surface condition from lands under grazing.


Six sites underwent a series of rainfall simulations to determine infiltration and runoff properties. Key surface soil features were recorded and the soil cores were taken to determine infiltration, moisture and compaction.

Key Findings

  • In general an increase in infiltration rate and a decrease in sediment concentration with an increase in ground cover was noted;
  • Greatest variations in infiltration were noted for covers <25% ground cover, while the greatest variation in sediment loss was noted for covers >75%; and
  • Total N and P losses did not correlate well with cover. However, concentrations of N and P were primarily influenced by sediment concentrations.


The selected sites are located within the Burdekin River Catchment west of Townsville.
