A first approach to assessing soil oxygenation in the field using the Tensionic ceramic tensiometer.

摘要

This paper describes a prototype method for assessing oxygen availability in soils using water injected into the ceramic cup of the Moutonnet Tensionic tensiometer. The water is recovered after several days of equilibration with the soil solution and the dissolved oxygen it contains is immediately measured with a field oxymeter. The easy installation, low cost of each device and rapid measurement allow numerous replications in the same plot, making it possible to obtain representative results. Certain meteorological refinements are still needed, but the consistency of the results already obtained suggests that the device offers interesting possibilities in various areas of agronomic studies.
