Comment:
Irrigated corn in the LTER Irrigated Resource Gradient Experiment (Irrigated N-rate Study).
Equipment used: Irrigated with the Valley 8000 Linear Irrigation System.
Amount of water applied: 0.825 inch of water was applied (as measured by six rain gauges).
Irrigation system delay setting: 25;
Irrigation pressure: 21 psi;
Pressure at the pump: 50 psi.
Time of application was between 9:15 a.m. - 11:00 a.m.
Weather conditions at 9:10 a.m. Sunny , 76.7°F, wind 1-4 mph (3m high 5 minute average wind speed was 1.29 mph) wind gust 4.34 mph, from the North, relative humidity 59.2%.
Weather conditions at 11:00 a.m. Sunny, 80.2°F, wind 2-5 mph (3m high 5 minute average wind speed was 2.39 mph), wind gust 5.09 mph, from the East, relative humidity 48%.
Meter reading at the start of irrigation event: 6,807,853 "FWD Total" on meter screen.
Meter reading at the end of irrigation event: 6,850,912
Total gallon of water used in this irrigation event (as measure by a in-line water meter): A minimum amount of 43,059 gallons of water was applied at time of irrigation.;
Average 426 gallons per minute (as measure by a in-line water meter).
This is the first irrigation event for the season where the in line meter was working.
The well pump shut off briefly around plots 507 and 708. The pump was restarted after stopping the irrigation system and irrigation was resumed. The irrigation system was backed up before restarting to make coverage as even as possible.
