| 2022-09-30 | Herbicide application to Lysimeter field, Resource Gradient Study, and T8nt plots. A tank mix of Round Up power max at 44 oz per acre (1.5 lbs per acre), 2-4D at 1 Quart per acre (3.325 pounds per acre), and Ammonium Sulfate at 3.4 lbs per acre were applied as a burndown. Rate of spray was 20gal/acre on JD rate controller. Application began at 12:30 pm, weather conditions at the time were: 58.5°F, wind speed 1.21 mph, wind direction East, relative humidity 62.5%, and sunny. Application concluded at 4:00 pm, weather conditions at the time were: 64.3°F, wind speed 1.03 mph, wind direction Northeast, relative humidity 49.2%, and sunny. REI: 12 hours. Application was completed using the 30ft top air sprayer and the John Deere 5220 tractor. | Ethan Rocklin | https://aglog.kbs.msu.edu/observations/5566 |
| 2022-08-05 | Application in T3 Reps 4,5,3,1,6,and 2 as well as the Resource Gradient irrigated and non irrigated plots. Applied Interline (Generic Liberty) at 36 oz/acre, Ammonium Sulfate at 3.4 lbs/acre, and a small amount of de-foaming agent. Rate of spray was 20gal/acre on JD rate controller. Weather conditions at the beginning 1:00pm: 76.5 degrees F, 1 mph east wind, 98.5% relative humidity, and cloudy. Weather conditions at the end 4:55 pm: 85.6 degrees F, 1.21 mph east wind, 64.2% relative humidity, and partly cloudy. REI: 12 hours. Application was completed using the 30ft top air sprayer and the John Deere 7420B tractor. | Leon Thelen | https://aglog.kbs.msu.edu/observations/5535 |
| 2022-07-22 | Harvested the LTER Main Site N-rate Study (Irrigated and non-Irrigated Resource Gradient) wheat. For each plot, a 5' wide strip the length of the plot was cut using the Kincaid combine. Moisture content and weight was determined by using the on-board Mirus system. | Leon Thelen | https://aglog.kbs.msu.edu/observations/5522 |
| 2022-07-01 | 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: 1.4375 inch of water was applied (as measured by six rain gauges). Irrigation system delay setting: 16; Irrigation pressure: 22 psi; Pressure at the pump: 50 psi. Time of application was between 9:25 a.m. - 11:55 a.m. Weather conditions at 9:30 a.m. mostly sunny, 76.4 degrees F, wind 0-10 mph (3m high 5 minute average wind speed was 1.0 mph) wind gust 9.59 mph, from the Southwest, relative humidity 60.3%. Weather conditions at 11:55 p.m. mostly sunny, 80.9 degrees F, wind 0-13 mph (3m high 5 minute average wind speed was 1.42 mph), wind gust 12.99 mph, from the Southwest, relative humidity 55.2%. Meter reading at the start of irrigation event: 4785085.0; Meter reading at the end of irrigation event: 4851650.6; Total gallon of water used in this irrigation event (as measure by a in-line water meter): 66,566 gallons of water was applied at time of irrigation. Average of 426 gallons per minute (as measure by a in-line water meter). | Joe Simmons | https://aglog.kbs.msu.edu/observations/5513 |
| 2022-06-27 | 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: 1.1 inch of water was applied (as measured by six rain gauges). Irrigation system delay setting: 19; Irrigation pressure: 23 psi; Pressure at the pump: 50 psi. Time of application was between 11:35 a.m. - 1:45 p.m. Weather conditions at 11:25 a.m. mostly sunny, 69.5 degrees F, wind 5-17 mph (3m high 5 minute average wind speed was 8.3 mph) wind gust 16.75 mph, from the Northwest, relative humidity 41.4%. Weather conditions at 1:45 p.m. mostly sunny, 69.5 degrees F, wind 8-24 mph (3m high 5 minute average wind speed was 11.54 mph), wind gust 23.02 mph, from the Northwest, relative humidity 35.4%. Meter reading at the start of irrigation event: 4683868.0; Meter reading at the end of irrigation event: 4741479.7; Total gallon of water used in this irrigation event (as measure by a in-line water meter): 57,612 gallons of water was applied at time of irrigation. Average about 427 gallons per minute. | Joe Simmons | https://aglog.kbs.msu.edu/observations/5506 |
