2019-10-18 Sprayed LTER Main Site N-Rate study and wheat stubble in the lysimeter field with AMS, and Roundup Powermax and 2,4-d ester. AMS applied at 3.4 lbs/A, Roundup Powermax applied at 1 qt/A, 2,4-D ester applied at 1 pt/A. Weather conditions at start 5:40 p.m. partly cloudy 56.1 degrees F, 6-7 mph South winds, 48.2 % humidity. Conditions at end 7:00 p.m. dusk, 54.9 degrees F, 4-5 mph South winds 52.2 % humidity. Justin Mezo https://aglog.kbs.msu.edu/observations/4610
2019-08-12 Sprayed LTER main site N-Rate Study and lysimeter field wheat stubble. Sprayed with Ammonium sulfate, Roundup PowerMax, Sharpen, and Cornbelt methylated soybean oil. AMS applied at 3.4 lbs/A, Roundup PowerMax applied at 1 qt/A, Sharpen applied at 2 oz/A, Cornbelt methylated soybean oil at .2 gallons/A. Weather conditions at the start 2:10 p.m. partly cloudy/overcast, 81.1 degrees F, 5-6 mph south west, 70.7 humidity. Conditions at the end 4:00 p.m. overcast, 82.6 degrees F, 5-6 mph South wind, 65% humidity. Justin Mezo https://aglog.kbs.msu.edu/observations/4468
2019-07-25 Harvested the LTER Main Site N-rate Study (Irrigated and non-Irrigated Fertility 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. Justin Mezo https://aglog.kbs.msu.edu/observations/4464
2019-07-05 Irrigated winter wheat in the LTER Irrigated Fertility Gradient Study (N-rate Study). The study was irrigated with the Valley 8000 Linear Irrigation System, 0.78 inch of water was applied (as measured by six rain gauges); Irrigation system delay setting: 28%; Irrigation pressure: 21 psi; Pressure at the pump: 50 psi; Time of application was between 9:20 a.m. - 10:45 a.m.; Weather conditions at the start (9:10 a.m.) mostly sunny, 82 degrees F, wind: 3.7 mph (9 ft) out of the southwest. R.H. 79% Weather conditions at the end (11:00 a.m.): mostly sunny, 86 degrees F, winds: 5.38 mph (9 ft) out of the southwest. R.H. 67% 43,219.3 gallons of water was applied at time of irrigation. Using 422 gals/min. during the irrigation event. Joe Simmons https://aglog.kbs.msu.edu/observations/4454
2019-07-03 Irrigated winter wheat in the LTER Irrigated Fertility Gradient Study (N-rate Study). The study was irrigated with the Valley 8000 Linear Irrigation System, .57 inch of water was applied (as measured by six rain gauges); Irrigation system delay setting: 40%; Irrigation pressure: 21 psi; Pressure at the pump: 50 psi; Time of application was between 9:45 a.m. - 10:45 a.m.; Weather conditions at the start (9:40 a.m.) mostly sunny, 77 degrees F, wind: 5 mph (9 ft) out of the north. R.H. 81% Weather conditions at the end (10:40 a.m.): mostly sunny, 80 degrees F, winds: 5.5 mph (9 ft) out of the northwest. R.H. 77% 34,484 gallons of water was applied at time of irrigation. Using 428 gals/min. during the irrigation event. Joe Simmons https://aglog.kbs.msu.edu/observations/4450
