To investigate available technology tools for farmers to make in-season management decisions for grain farming in the Esperance Port Zone (EPZ). Until recently, Yield Prophet was the most well-known yield estimation tool, however there are now other options becoming available. SEPWA looked at how other in-season management tools measure up in a comparability study, looking predominately at five tools used to forecast yield and manage inputs.
Estimating what a paddock will yield allows growers to manage herbicide and fertiliser inputs during the season; forward sell grain and accurately insure their crops. This is an important tool for managing gross margins and ensuring profitability.
