2017-12-01 Flail mowed corn stalks in LTER N-Rate Nitrogen study both irrigated and non irrigated, CE study corn plots, corn and soybean plots in biodiversity as well as the spring fallow plots. Justin Mezo https://aglog.kbs.msu.edu/observations/4094
2017-10-27 Harvested corn from the LTER N-rate Study (Irrigated only Fertility Gradient). For each plot two rows of corn were harvested from the middle of each plot (rows 3 and 4 from each plot). Plot weight and moisture content were obtained from the on-board Mirus software by Harvest Master. A sample of grain was collected and bagged from each plot this year. Samples were requested by Bonnie McGill (grad student). Harvested with Kincaid 8XP plot combine. Joe Simmons https://aglog.kbs.msu.edu/observations/4065
2017-10-20 Harvested corn from the LTER N-rate Study (Non-Irrigated only Fertility Gradient). For each plot two rows of corn were harvested from the middle of each plot (rows 3 and 4 from each plot). Plot weight and moisture content were obtained from the on-board Mirus software by Harvest Master. A sample of grain was collected and bagged from each plot this year. Samples were requested by Bonnie McGill (grad student). Harvested with the Kincaid 8XP plot combine. Doug Reed was the staff member that helped collect samples today.

2017-09-22 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.

2017-09-13 Irrigated the LTER Irrigated Resource Gradient Study (N-rate Study). Equipment Used: Irrigated with the Valley 8000 Linear Irrigation System. 0.64 inch of water was applied (as measured by six rain gauges); Irrigation system delay setting: 32%; Water pressure at the Linear system: 21-22 psi; Water Pressure at the well/pump: 50 psi; Time of application was between 10:05 a.m. and 11:30 a.m.; Weather conditions at the start: (10:00 a.m.): cloudy, Temperature: 63 degrees F, Relative Humidity: 78%, Dew Point ? degrees F, Wind: 3.18 mph (5 minute average at 9 ft) out of the Northeast; Maximum wind gust in the last hour: 5.12 mph (at 33 ft); Soil Temp: 65 degrees F, Soil Moisture: 9.1%; Weather conditions at the end: (11:30 a.m.): cloudy, Temperature: 70 degrees F, Relative Humidity: 69%, Dew Point 59 degrees F, Wind: 2.18 mph (5 minute average at 9 ft) out of the Southeast; Maximum wind gust in the last hour: 7.44 mph (at 33 ft); Soil Temp: 78 degrees F, Soil Moisture: 9.1%; 36,770 gallons of water was applied during this irrigation event; At 50 psi we are using about 400 GPM gallons of water per minute.
