Irrigation Applications
Well Registration #:
(www.dnr.ne.gov Please enter all irrigation wells associated with this field)
Acres Irrigated:
Crop Water Use: inches (http://cropwatch.unl.edu click on Weather > GDD,ET)
Flow Rate: gpm
Total Hours: (Total hours of irrigation)
Irrigation Type: (Enter type of irrigation system. E.g., High Pressure, Low Pressure, etc.)
Total Rainfall for Season: inches (Enter total rainfall during the growing season)
Flowmeter Reading:
(If flowmeter is installed please enter 2017 beginning and end reading)
null inches/acre Calculated from Flowmeter Reading if provided, otherwise calculated from flow rate and total hours
Soil Analysis
Soil Nitrate-N (Residual soil nitrates from FALL 2017 deep soil sample results, if only 2 layers are sampled leave layer 3 blank).
Example: 0 to 8 inches is 15 ppm, 8 to 24 inches is 10ppm, and 24 to 48 inches is 3ppm.

Nitrogen Application and Yield
Actual N Applied: lbs N/acre
Expected Yield (EY): bu/acre
Actual Yield: bu/acre
UNL Recommended N Formula for CORN
35 + (1.2* EY ) - (8 * NO3-N ppm) - (0.14 * EY * OM% ) - credits = lbs N/per acre


EY = expected yield (bu/acre)
NO3-N ppm = average nitrate - N concentration in the root zone (2-4 foot depth) in ppm. If root zone nitrogen is not provided default values will be used based on soil type.
OM% = percent organic matter; Credits = legume, manure, irrigation, or any other N credit

The fertilizer recommendation listed above uses conservative values to avoid under-fertilization.
Crop Damage
Check if this field experienced yield impacting damage from hail, wind, etc.
