Canola response to phosphorous in the Forbes district locations
Aims

To investigate canola response to phosphorous in the Forbes district.

Key messages

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".
