Irrigated winter wheat 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: 1.26 inch of water was applied (as measured by six rain gauges).
Irrigation system delay setting: 16;
Irrigation pressure: 21 psi;
Pressure at the pump: 50 psi.
Time of application was between 10:45 a.m. - 1:10 p.m.
Weather conditions at 10:40 a.m. Clear and Sunny , 88.2°F, wind 3-5 mph (3m high 5 minute average wind speed was 3.85 mph) wind gust 12.93 mph, from the South West, relative humidity 65.9%.
Weather conditions at 1:00 p.m. Partly Cloudy, 89.2°F, wind 5-7 mph (3m high 5 minute average wind speed was 5.43 mph), wind gust 12.93 mph, from the West, relative humidity 59%.
Meter reading at the start of irrigation event: 6,740,097.0;
Meter reading at the end of irrigation event: 6,749,816.9;
Total gallon of water used in this irrigation event (as measure by a in-line water meter): A minimum amount of 9,719.9 gallons of water was applied at time of irrigation.; (The meter was froze up and not calculating gallons shortly after turning on. The gallon amount should be much higher.
Average 423 gallons per minute (as measure by a in-line water meter).
Because the in-line water meter 'froze up' or was not working correctly shortly after turning on this date, therefore the meter was not calculating gallons correctly. On June 24, 2025 the amount of water on the meter was 9,719.6 gallons of water applied at the time of the irrigation event. However, the average gallons per minute (as measure by the in-line water meter was 423 gallons per minute. The irrigation event on June 24, 2025 was ~ 145 minutes: 145 min * 423 gallons per minute = ~ 61,335 gallons (estimated) for the irrigation event on June 24, 2025.
