2024-10-10 | Planted winter wheat in the Resource Gradient Experiment, both Irrigated and Rainfed plots. Wheat was also planted into the T8nt plots. Wheat variety: Pioneer 25R40 which is a soft red winter wheat, the seed was treated. Pioneer 25R40 (treated seed) had 10,500 seeds/lb (90% germ) planted at projected 134.5 lbs/A. Planting depth: 1-1.5”. Planted with JD 7420b tractor and JD 1590 no-till drill. Average planting speed was 4 mph. Seed drill was set to 44 using the second door notch, Seed rate was 1,412,250 seeds per acre. | Jarrod Rhoades | https://aglog.kbs.msu.edu/observations/6411 |
2024-10-07 | Harvested soybeans from the LTER Main Site N-rate Study (Resource Gradient, Irrigated). For each plot four rows of soybeans (5' wide) were harvested for yield using the Kincaid plot combine. Moisture content and weight were determined by using the on-board Mirus software, grain moisture was verified with the FSC Dickey John moisture tester. Grab samples of the grain from each plot was collect for the lab. Only Irrigated side harvested on 10/7/24. | Jarrod Rhoades | https://aglog.kbs.msu.edu/observations/6450 |
2024-10-03 | Harvested soybeans from the LTER Main Site N-rate Study (Resource Gradient, non-Irrigated). For each plot four rows of soybeans (5' wide) were harvested for yield using the Kincaid plot combine. Moisture content and weight were determined by using the on-board Mirus software, grain moisture was verified with the FSC Dickey John moisture tester. Grab samples of the grain from each plot was collect for the lab. Only Non-Irrigated side harvested on 10/3/24. | Ethan Rocklin | https://aglog.kbs.msu.edu/observations/6401 |
2024-09-17 | Irrigated soybeans 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: 0.5417 inch of water was applied (as measured by six rain gauges) Irrigation system delay setting: 39; Irrigation pressure: 21 psi; Pressure at the pump: 51 psi. Time of application was between 9:29 a.m. - 10:30 a.m. Weather conditions at 9:15 a.m. Sunny , 63.4 °F, wind 2 mph (3m high 5 minute average wind speed was 2.04 mph) wind gust 1.15 mph, from the Northeast, relative humidity 91.5%. Weather conditions at 10:16 a.m. Sunny, 68.4 °F, wind 3 mph (3m high 5 minute average wind speed was 2.96 mph), wind gust 1.15 mph, from the East, relative humidity 67.3%. Meter reading at the start of irrigation event: ?; Meter reading at the end of irrigation event: ?; Total gallon of water used in this irrigation event (as measure by a in-line water meter): A minimum amount of ??? gallons of water was applied at time of irrigation.; Average ??? gallons per minute (as measure by a in-line water meter). | Ethan Rocklin | https://aglog.kbs.msu.edu/observations/6390 |
