Other claims from this paper (8)
- Intervention effect Liming under CaNPK reduced blueberry yield most strongly.
- Intervention effect Blueberry yield responded weakly to potassium fertilization.
- Intervention effect Yield in PN plots was about 10% lower than in NPK plots.
- Intervention effect Yield without phosphorus fertilization was similar to fertilized plots.
- Intervention effect Annual P fertilization increased leaf P levels.
- Intervention effect Annual K fertilization increased leaf K levels.
- Intervention effect Liming increased leaf Ca and Mg levels.
- Intervention effect Liming decreased leaf Fe, Zn, and Mn levels.
