Measurement of soil water content in a peat-vermiculite medium using time domain reflectometry (TDR): a laboratory and field evaluation
1996
Lambany, G. | Robidas, L. | Ballester, P.
In Quebec, Canada, the estimation of soil water requirements in container tree seedling production is generally based on a qualitative approach. However, recently, the development of large seedling cultivation and the use of air-slit containers have made nursery irrigation more complex. In order to improve irrigation management, we evaluated the use of time domain reflectometry (TDR) equipment to measure the volumetric content of substrates. Trials carried out show that this type of equipment can be used to measure substrate water content in real time. Comparison with measures of soil water content determined gravimetrically confirms that measurements obtained by TDR are very precise.
