SAGIT Benchmark Testing Results and Analysis from Dr Nick Berry

Nick discusses the testing results conducted by the South Australian Grains Industry Trust by Trengrove Consulting. The testing aimed to compare different mills and chaff material types in the industry. Nick provides insights into the testing process, the outcomes, and the implications for the industry. The video includes essential data and highlights seed size and energy impact.

06:50 Why small seeds are harder to kill
08:28 What is a normal Ryegrass seed size in Australian Paddocks?
08:47 Are seeds smaller than 2.1 actually viable?
09:00 Energy used during the test is proportional to the Seed kill (Pprocessing)
