To investigate canola response to phosphorous in the Forbes district.
These results highlight the potential for canola yields to be increased with extra P fertiliser rates above 20 kg P/ha. However, fertiliser research has indicated high rates of starter fertilisers such as MAP and DAP can have a negative impact on seedling germination due to fertiliser "burn".
