A framework relating soil surface condition to infiltration and sediment and nutrient mobilisation in grazing rangelands of North-eastern Queensland, Australia – Site 1 Thalanga

Level 1: General Description


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


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