|---|---|---|---|
| 2023-12-14 | Mowed corn stubble after harvest in Lysimeter field and the irrigated and non-irrigated fertility gradient study. Mowed corn stubble in the T8nt plots as well. JD 7420 and 15' JD flail mower was used. | Jarrod Rhoades | https://aglog.kbs.msu.edu/observations/6114 |
| 2023-11-18 | Harvested corn from the LTER Main Site N-rate Study (Resource Gradient, Irrigated and non-Irrigated). For each plot two rows of corn (5' wide) were harvested for yield using the Kincaid plot combine. Moisture content and weight were determined by using the on-board Mirus software. Grab samples of the grain from each plot was collect for the lab. Rows 2 and 5 were harvested out of each plot on 12/8/23 to double check the data of the main harvest. Equipment Used: Kincaid plot combine and small grain truck. Cleaned-up (harvested) remaining corn rows of corn on December 11th, 2023. Equipment Used: JD S660 combine and small grain truck. | Joe Simmons | https://aglog.kbs.msu.edu/observations/6072 |
| 2023-09-28 | 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: 0.5875 inch of water was applied (as measured by six rain gauges) Irrigation system delay setting: 32; Irrigation pressure: 22 psi; Pressure at the pump: 50 psi. Time of application was between 10:35 a.m. - 11:50 a.m. Weather conditions at 10:25 a.m. Cloudy/drizzling , 59.2 °F, wind 5-10 mph (3m high 5 minute average wind speed was 5.41 mph) wind gust 9.77 mph, from the Northeast, relative humidity 99.3%. Weather conditions at 11:40 a.m. Cloudy, 59.8 °F, wind 7-12 mph (3m high 5 minute average wind speed was 7.05 mph), wind gust 12.1 mph, from the Northeast, relative humidity 97.9%. Meter reading at the start of irrigation event: 5,965,004; Meter reading at the end of irrigation event: 5,992,525; Total gallon of water used in this irrigation event (as measure by a in-line water meter): A minimum amount of 27,521 gallons of water was applied at time of irrigation.; The flow meter was not working at the beginning of the event but then started working. The total amount of gallons appears to be a little low for what it should be for the amount of time it was running. Average 420 gallons per minute (as measure by a in-line water meter). | Jarrod Rhoades | https://aglog.kbs.msu.edu/observations/6028 |
| 2023-09-20 | 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: 0.517 inch of water was applied (as measured by six rain gauges) Irrigation system delay setting: 37; Irrigation pressure: 22 psi; Pressure at the pump: 50 psi. Time of application was between 10:10 a.m. - 11:15 a.m. Weather conditions at 10:10 a.m. Sunny , 65.2 °F, wind 3-7 mph (3m high 5 minute average wind speed was 3.88 mph) wind gust 7.26 mph, from the South, relative humidity 77.3%. Weather conditions at 11:15 a.m. Sunny, 70.5 °F, wind 4-13 mph (3m high 5 minute average wind speed was 4.4 mph), wind gust 13.55 mph, from the Southwest, relative humidity 62.5%. Meter reading at the start of irrigation event: 5,933,096; Meter reading at the end of irrigation event: 5,965,003.6; Total gallon of water used in this irrigation event (as measure by a in-line water meter): A minimum amount of 31,907.6 gallons of water was applied at time of irrigation.; The flow meter worked for this event each time it was checked. The total amount of gallons appears to be close to what it should be for the amount of time it was running. Average 402 gallons per minute (as measure by a in-line water meter). | Jarrod Rhoades | https://aglog.kbs.msu.edu/observations/6024 |
| 2023-08-30 | 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: 0.683 inch of water was applied (as measured by six rain gauges) Irrigation system delay setting: 28; Irrigation pressure: 22 psi; Pressure at the pump: 50 psi. Time of application was between 10:50 a.m. - 12:15 p.m. Weather conditions at 10:40 a.m. Mostly Sunny , 61 °F, wind 5-10 mph (3m high 5 minute average wind speed was 5.33 mph) wind gust 13.35 mph, from the Northwest, relative humidity 71.5%. Weather conditions at 12:10 p.m. Sunny, 63.8 °F, wind 8-15 mph (3m high 5 minute average wind speed was 8.06 mph), wind gust 16.03 mph, from the North, relative humidity 57.8%. Meter reading at the start of irrigation event: 5,892,704; Meter reading at the end of irrigation event: 5,820,248.7; Total gallon of water used in this irrigation event (as measure by a in-line water meter): A minimum amount of 27,544.7 gallons of water was applied at time of irrigation.; The flow meter was intermittently working so the total could be off some. The total amount of gallons appears to be close to what it should be for the amount of time it was running. Average 410 gallons per minute (as measure by a in-line water meter). | Jarrod Rhoades | https://aglog.kbs.msu.edu/observations/6013 |
