Comment:
Because the corn has not reached black layer (physiological matured) to date and with 5-6 days of 85 - low 90 degrees F in the forecast we decide to irrigate the N-rate corn today.
Irrigated the LTER Irrigated Resource Gradient Study (N-rate Study).
Equipment Used: Irrigated with the Valley 8000 Linear Irrigation System.
0.80 inch of water was applied (as measured by six rain gauges);
Irrigation system delay setting: 28%;
Water pressure at the Linear system: 21-22 psi;
Water Pressure at the well/pump: 50 psi;
Time of application was between 8:05 a.m. and 9:45 a.m.;
Weather conditions at the start: (8:00 a.m.):
Sunny, Temperature: 64 degrees F, Relative Humidity: 98%, Dew Point 63 degrees F, Wind: 1.00 mph (5 minute average at 9 ft) out of the Northeast; Maximum wind gust in the last hour: 3.33 mph (at 33 ft); Soil Temp: 63 degrees F, Soil Moisture: 9.4%;
Weather conditions at the end: (9:45 a.m.):
Sunny, Temperature: 76 degrees F, Relative Humidity: ?%, Dew Point 67 degrees F, Wind: 2.28 mph (5 minute average at 9 ft) out of the South; Maximum wind gust in the last hour: 2.43 mph (at 33 ft); Soil Temp: 72 degrees F, Soil Moisture: 9.4%;
42,740 gallons of water was applied during this irrigation event;
At 50 psi we are using about 400 GPM gallons of water per minute.
