Break crop benefits in low P environments: Is phosphorous a factor? locations
Aims

To determine the ways in which different crop types influence available soil P and the P requirements of subsequently sown cereals

Key messages

Wheat yields were highest when grown after chickpeas or lupins at both low and moderate phosphorus (P) sites. Benefits provided by the previous chickpea or lupin crops could not be attributed to an increase in residual P sources alone.
