Piatt County Service Co. and the Piatt County Farm Bureau are teaming up to demonstrate the impact of implementing 4R nutrient stewardship practices. The data gathering process on practices such as split application and use of nitrogen inhibitors will include tissue samples, a DTN weather station, and nitrogen rate trials.
Piatt County Service Company is working on a 4R4U nitrogen management plot in Monticello. This nitrogen management plot is looking at five different rates and timing of nitrogen applications.
N-Serve is a nitrogen stabilizer that helps ensure nitrogen is available in the root zone. When applied with anhydrous ammonia, N-Serve inhibits nitrification. Next steps for the plot are to monitor the field through Climate FieldView software.
Thanks to Jared Gregg for working on this 4R4U nitrogen management trial.
For the month of July average high temperatures were 80.7 degrees while the average low daily temperature was 61.8 degrees. These seasonal temperatures recorded the highest single day temperature on the 6th at 90 degrees while the lowest daily high was 68 degrees on the 14th. July saw well above average rainfall through the month with a total of 10.71 inches for the month. The highest daily amount was 3.07 on the 21st which occurred during a 5 day rain event that dropped 7.6 inches. For the month a total 633 Growing Degree Units (GDU) were received with the highest daily amount recorded of 26 recorded on several day in mid-July.
June saw a stark contrast in weather conditions from the previous two months with unseasonably warm and dry weather. For the month average high temperature was 85.2 degrees while the average low daily temperature was 61.4 degrees. The first 2 weeks of June saw zero perception recorded while averaging 88.7 degree under windy conditions. Some rainfall did occur in later half of June however; monthly rainfall total at the site was 1.03 inches compared to 6.0 inches the previous month. Growing Degree Units (GDU) accumulated was 669 with the highest daily amount recorded on the 13th at 30. Evapotranspiration for the month totaled 7.6 inches leaving a shortfall of 6.57 inches compared to precipitation.
Evapotranspiration (ET) is the sum of evaporation and plant transpiration. Evaporation accounts for the movement of water to the air from sources such as the soil, canopy interception, and waterbodies. Transpiration accounts for the movement of water within a plant and the subsequent loss of water as vapor through stomata in its leaves.
May began unseasonably cool with a low of 38 degrees on the 1st before temperatures rose steadily to reach a high of 90 degrees on May 18th ahead of a cold front that produced substantial rainfall and declining temperatures. Average air high temperature was 73.1 degrees while the average low daily temperature was 52.9 degrees. Average daily soil temperatures peaked at 67 degrees on May 30th with the last 22 days of the month maintaining soils above 60 degrees. A drier weather pattern was seen from May 10th – 18th which allowed for field work to make progress. Monthly rainfall total at the site was 6.0 inches with the highest daily amount or 1.39 inches on May 19th. For the month a total 413 Growing Degree Units (GDU) were received with the highest daily amount recorded on the 17th at 27.
April average air high temperature was 69.0 degrees while the average low daily temperature was 47.3 degrees. A high of 83 degrees was reached 3 separate times on April 14th, 15th, and 19th. The lowest of 32 degrees was recorded on April 7. For the month of April, a total 308 Growing Degree Units (GDU) were received with the highest daily amount recorded on April 15 at 22(GDU). Average daily soil temperatures peaked on April 20 at 64 degrees with a low of 48 degrees on April 7. The average soil temperature for the month was 55.3 degrees. Soils maintained 50 degrees or higher all but 3 days in April which would have stimulated microbial activity converting ammonium nitrogen to nitrate. Monthly rainfall total at the site was 4.51 inches with the 2.5 inches of that total coming during the last 2 days of the month. Saturated field conditions along with a high percentage of nitrogen in the nitrate form may have increased the potential for denitrification and leaching.
