agrophysics - Opis:
- Influence of the measuring procedure on the repeatability of measurement of the potential oxygen flux density in the soil has been presented. Five measuring procedures were applied: measurements taken one directly after another, reinstallation of the electrode after each measurement , reinstallation of the electrode after each measurement with a simultaneous mechanical cleaning of surfaces, measurements with 15-min breaks between consecutive measurements, measurements with electrochemical "cleaning" of the electrode surface.The OFD value was determined by a voltamperometric method using a tri-electrode measuring system. It was found out that the best repeatability can be obtained by repeating the measurement with 15-min (or longer) time intervals.
