to outline gross margin scenarios under a range of fertiliser and grain prices which could be vastly different to those set up in previous seasons. Importantly the gross margin analysis will be performed using a range of different background P levels, soil type characteristics and yield potentials.
• Opportunities are available for reformed phosphorus (P) rates under high fertiliser prices, but background knowledge is key.
• Gross margin analysis with phosphorus application rates is sensitive to soil available, yield potential, fertiliser, and grain prices.
• On phosphorus responsive soil types, return from fertiliser (P) investment is normally greatest and most stable with cereal phases.
