- Intervention effect Increasing salinity raised leaf sodium from 0.37% to 1.39%.
- Intervention effect Increasing salinity raised leaf chloride from 1.75% to 5.73%.
- Intervention effect Increasing salinity raised fruit sodium from 0.08% to 0.26%.
- Intervention effect Increasing salinity raised fruit chloride from 0.63% to 1.34%.
- Observation First cluster leaves had 54% more sodium than fifth cluster leaves.
- Observation First cluster leaves had 32% more chloride than fifth cluster leaves.
- Observation Old leaves accumulated 25% more chloride than younger leaves.
- Intervention effect Increasing salinity lowered leaf nitrate from 1.21% to 0.50%.
- Intervention effect Increasing salinity lowered leaf total nitrogen from 3.31% to 3.03%.
- Intervention effect Increasing salinity lowered leaf sulphate from 3.71% to 3.12%.
- Intervention effect Increasing salinity lowered leaf potassium from 2.76% to 1.51%.
- Observation Potassium reduction was more evident in younger than older leaves.
- Intervention effect Increasing NaCl decreased fruit macronutrients other than calcium.
- Intervention effect Fruit phosphate fell 35% only in the fifth cluster.
- Observation First truss fruit had higher concentrations of all measured ions.
- Mechanism The authors attributed tomato biomass reduction partly to sodium and chloride toxicity.
- Observation Macronutrients generally stayed above growth limiting deficiency levels except potassium.
