- Association Leaf N, P, K and Mg generally decreased with leaf age.
- Association Leaf Ca rose quickly in young leaves and then varied little.
- Recommendation Leaves aged 3 to 6 and 10 months are suitable sampling material with corresponding standards.
- Intervention effect Nitrogen fertilizer increased leaf nitrogen linearly.
- Intervention effect Fertilizer increased leaf phosphorus linearly.
- Intervention effect Potassium rose only with one fertilizer dose.
- Intervention effect Nitrogen fertilizer tended to reduce leaf P and K.
- Intervention effect Nitrogen fertilizer tended to increase leaf Mg.
- Intervention effect Superphosphate increased leaf Ca.
- Intervention effect Potassium fertilizer lowered leaf Ca and Mg.
- Association A significant negative correlation was found between nitrogen and phosphorus.
- Association A significant negative correlation was found between nitrogen and calcium.
- Association A significant negative correlation was found between potassium and calcium.
- Association A significant negative correlation was found between potassium and magnesium.
