Calculations to determine fertilizer weight (B) for the desired application rate:
____ A (lbs/acre) x____ C (rev) x _____D (ft) x _____ E (ft) ÷ 43,560 = ______ B (lbs)
____ A (kg/ha) x _____ C (rev) x _____ D (m) x _____ E (m) ÷ 10,000 = ______ B (kg)
A = application rate (desired rate lbs/acre or kg/ha);
B = weight of fertilizer (lbs or kg) collected from applicator(s) from one row during (C) revolutions
C = number of the drive wheel revolutions
D = “actual” drive wheel circumference (ft or m)
E = row spacing (ft or m)
