LIQUID FERTILIZER APPLICATION RATE AND PRESSURE CHART
TABLES ARE BASED ON 30” NOZZLE SPACING
Values in this chart area based on using water. To calculate nozzle size required for your fertilizer application, the weight of the
fertilizer solution must be accounted for by using a conversion factor for specific gravity. The Conversion factor for 28% liquid nitrogen
is 1.13. Example: desired rate of application is 10 GPA of 28% N multiply 10 gallons per acre of fertilizer you want to apply x the
conversion factor for 28% N (1.13) to get an equivalent rate for water. 10 x 1.13 refers to the chart for 11.13 gallons per acre at your
desired speed/MPH.

FACTOR
(Per Nozzle) MPH X W
GPA = GALLON PER ACRE
28% = H20/1.13
GPM = GALLON PER MINUTES
32% = H20/1.15
MPH = MILES PER HOUR
W = WIDTH
