Rapid Percolation of Water through Soil Macropores Affects Reading and Calibration of Large Encapsulated TDR Sensors

Popis výsledku v původním jazyce

The electromagnetic soil water content sensors are useful because of their selective sensitivity to water, versatility, ease of automation and large resolution. Their drawback is their preferential sensitivity to water near to their surfaces. This effectwas explored for large Time-Domain Reflectometry (TDR) sensors Aqua-Tel-TDR (Automata, Inc., now McCrometer CONNECT). Their field performance was investigated and compared with the results of field and laboratory calibration. The field soil was loamy Chernozem on a carbonate-rich loess substrate, while the laboratory calibration was done in fine quartz sand. In the field, the sensors were installed horizontally into pre-bored holes after being wrapped in slurry of native soil or fine earth. Large sensor-to-sensor variability of readings was observed. It was partially removed by field calibration. Percolation events made the TDR readings suddenly rising and sometimes considerably exceeding the saturated water content. After the events,
