Filling the Nutrient Gap locations
Aims

3 different crop species were planted to measure the responses to P; this will assist in crop data gaps being able to be filled allowing for better fertiliser decisions to be made.

Key messages

Knowing phosphorous levels in the soil is critical. At low levels of nutrition, an economic response to phosphorous application will be achieved. This work is critical in determining where the nutrient response curve flattens out – allowing for improved management decisions to be made.
