Erosion Victoria, December 2021

Second visit during the 2021 Summer season to reassess the Victorian site locations from Autumn. Monitoring erosion risk based on dry aggregates and groundcover percentages.

This farm is located west of Merbein South in the Millewa.

Victoria, Grazed and Ungrazed

2021 Summer Erosion Victoria Grazed and Ungrazed

1. Grazed is a sandy loam which was bare through 2019, but established a crop in 2020 and where electric fencing was used to protect the eastern side of the paddock from grazing. 2. Ungrazed is a sandy loam on the western grazed side of the paddock directly adjacent to 1. Grazed. Summer monitoring showed 1. ground cover of 46% and dry aggregate of 24% with a medium risk of erosion and 2. Ungrazed with ground cover of 67% and dry aggregate of 39% with a low risk of erosion

Victoria, Flat Calcareous Soil

2021 Summer Erosion Victoria Flat Calcareous Soil

Flat Calcareous Soil is a poor calcareous sandy loam flat that blew through 2018 and 2019 but established crop in 2020. Being near sheep feeders it has attracted reasonable grazing pressure and sheep tracks. Summer monitoring showed 3. Flat Calcareous Soil with ground cover of 27% and dry aggregate of 49% with a medium risk of erosion

2021 Summer Erosion Victoria Sandy Soil

Sandy Soil or Sandy Loam during Summer monitoring showed 4. Sandy Soil with ground cover of 48% and dry aggregate of 27% with a medium risk of erosion

Ungrazed is a sandy loam on the western grazed side of the paddock directly adjacent to 1. Grazed. Autumn monitoring showed 1. Grazed with a residue height of 9cm, ground cover of 63% and dry aggregate of 25% with a low risk of erosion and 2. Ungrazed with a residue height of 1cm, ground cover of 13% and dry aggregate of 19% with a high risk of erosion
