Summary: Cereal growers should understand their store of nitrogen reserves in the soil before applying in crop nitrogen. Nick Poole from the Foundation for Arable Research says nitrogen rates should vary from year to year both in their timing and rate, based on the previous season. He says growers should aim to grow a crop canopy that is an average of canopies over the previous 10 years. Contact: Nick Poole Email: poolen@far.org.au
