ABSTRACT
In a laboratory experiment, soil moisture was measured by means of a TDR-moisture-meter. Corresponding water content values were available from measurements of the gravimetric water content and the bulk density of the soils. Results for the period 1995-2000 confirmed the factory installed calibration functions and indicated that there was no long term drift of the TDR-system used.

W doświadczeniu laboratoryjnym prowadzono pomiar wilgotności gleby za pomocą miernika wilgotności TDR. Odpowiednie wartości zawartości wody w glebie były dostępne z pomiarów grawimetrycznej zawartości wody oraz gęstości objętościowej gleb. Wyniki uzyskane za okres 1995-2000 potwierdziły fabrycznie zainstalowane funkcje kalibracyjne miernika oraz wykazały brak przesunięcia czasowego w zastosowanym systemie TDR.
