Other claims from this paper (10)
- Association Nutrient solution pH significantly affected root and shoot K concentrations, root Ca concentration, Ca uptake and shoot Mg concentration.
- Association Nutrient solution pH had nonsignificant effects on Na concentrations and uptake and root Mg concentration and uptake.
- Intervention effect Raising solution pH from 4.5 to 8 significantly decreased spinach K and Ca uptake.
- Intervention effect Raising solution pH significantly increased shoot K and Mg concentrations and root Ca concentration.
- Association Nitrate to ammonium ratio and its interaction with pH significantly affected root and shoot K, Ca, Mg and Na concentrations and uptake.
- Intervention effect Decreasing the nitrate to ammonium ratio significantly decreased spinach root and shoot K, Ca, Mg and Na concentrations and uptake.
- Association The effect of nitrogen ratio on spinach mineral concentrations and uptake depended on solution pH and vice versa.
- Observation Average shoot concentrations of K, Ca, Mg and Na exceeded root concentrations.
- Association Shoot and root element concentrations were significantly correlated.
- Association Shoot element concentrations and plant uptake were significantly correlated.
