The following points highlight the six factors affecting absorption of mineral salt in plants. The factors are: 1. Temperature 2. Hydrogen Ion Concentration 3. Light 4. Oxygen Tension 5. Ion Interaction and 6. Growth. Factor # 1. Temperature: Generally, an increase in temperature up to a certain limit brings about an increase in rate of salt absorption. However, this effect [...]
