Potatoes are considered to have a low phosphorus (P) uptake efficiency compared to most other crops. As potatoes require phosphorus throughout the growing season, phosphorus fertiliser inputs are commonly high.
This case study examines the role of phosphorus availability and uptake in a potato crop throughout the growing season. It shares the results of a trial in north-west Tasmania of a new liquid phosphorus fertiliser applied to processing potatoes in P-fixing soils.
