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: 1.0 inch of water was applied (as measured by five rain gauges) Irrigation system delay setting: 20; Irrigation pressure: 21 psi; Pressure at the pump: 47 psi. Time of application was between 10:05 a.m. - 11:55 a.m. Weather conditions at 10:00 a.m. Clear and Sunny , 76.5 °F, wind 1-5 mph (3m high 5 minute average wind speed was 1.71 mph) wind gust 4.76 mph, from the Southwest, relative humidity 78.5%. Weather conditions at 11:55 a.m. Clear and Sunny, 79.2 °F, wind 2-7 mph (3m high 5 minute average wind speed was 2.06 mph), wind gust 6.73 mph, from the West, relative humidity 65.3%. Meter reading at the start of irrigation event: 5390602.9; Meter reading at the end of irrigation event: 5441786.3; Total gallon of water used in this irrigation event (as measure by a in-line water meter): A minimum amount of 51,183.4 gallons of water was applied at time of irrigation.; Think that we have an air pocket in the flow meter which causes the flow meter to work intermittently. The 51,183.4 gallons was the minimum amount of water applied during this irrigation event. The flow meter was working most of the time during this irrigation event but it was working intermittently so more gallons of water would have been applied during this irrigation event. Average 407 gallons per minute (as measure by a in-line water meter).
