Victoria, Grazed and Ungrazed

2021 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. 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

Being near sheep feeders it has attracted reasonable grazing pressure and sheep tracks. Autumn monitoring showed 3. Flat Calcareous Soil with a residue height of 1cm, ground cover of 13% and dry aggregate of 19% with a low risk of erosion
