Fig. 3. ECH2O sensor data for the four experiments. *Note: Experimenter error led to over-irrigation of 100% actual ET replacement subplots on days 1 and 2 in experiment 1. Irrigation on day 3 of experiment 2 and day 2 of experiment 4 was cancelled due to high winds. Irrigation on day 7 of experiment 4 was cancelled due to rain (rain cover deployed). In each case of a missed irrigation application, the two-day total of irrigation was applied the following day.
