Control of growing medium water content and its effect on small seedlings grown in large containers

Lambany, G. | Renaud, M. | Beauchesne, M.
Results of an experiment carried out in a tunnel house confirm that real-time operational monitoring of water content in a peat-vermiculite substrate is possible using equipment based on the principles of time domain reflectometry. Irrigation management can still be easy despite the use of air-slit containers. Soil water content can be significantly reduced without affecting tree seedling development. Small seedlings, which have low soil water requirements and a large quantity of water in each cavity, may explain these results. However, reduction in soil water content did not prevent roots from growing from one cavity to the next.
