Control of Growing Medium Water Content and Its Effect on Small Seedlings Grown in Large Containers
Results of an experiment carried out in a tunnel house confirm that real-time operational monitoring of water content in a peatvermiculite 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. Tree Planters' Notes 48 (3/4): 48-54; 1997.
