Controlled water potential in subirrigated pots
- 35 Downloads
A simple method of control for soil water potential in subirrigated pots is presented. The system is tested in a glasshouse trial. No uncontrolled excursions in soil water potential were observed, and the soil water tension was held constant to less than ±15%. Reasons for fluctuations in potentials and recommendations for their reduction are made.
