- Association Desiree and Maris Piper accumulated much more N and K than was applied as fertilizer.
- Intervention effect Increasing planting density increased nutrient accumulation in potato.
- Intervention effect Increasing planting density had only small effects on potato yields.
- Association High yields in potato are associated with, but not necessarily caused by, large nutrient accumulations.
