Crop production using replacement P rates locations
Aims

To monitor crop production and economic outcomes from applying P at nil, replacement, average and twice average rates on both a deep sandy loam and a shallow constrained soil.

Key messages
  • A replacement P strategy produced similar yields to 10 and 20 kg/ha P rates in 2010.
  • The trial indicated an economic benefit in increasing P rates up to 20 kg/ha on a deep sandy loam in 2010.
