Sum16-30 P rates on high PBI soils, Darkan


To assess how barley responds to phosphorus (P) fertilizer applications under high soil phosphorus buffering index (PBI) conditions

Fig 1: Yield Response to Phosphorus


Despite relatively high P in the soil test (61 mg/kg), PBI was high on this forest gravel and 24 kg/ha of P applied at seeding optimised yield and gross margin under these conditions.
