Establishing sustainable P rates on varying soil types locations
Aims

To measure comparative wheat yields in response to varying P applications on 2 soil types.

Key messages
  • Applying 20 kg/ha of phosphorus (P) increased grain yield and protein content above a replacement P rate, however there was little economic benefit from the extra P on either a deep or a shallow constrained soil in 2009.
