Figure 9.2: Scale for calculation of the nominal output quantity per minute
Calculation with formula
The nominal output quantity can also be calculated using the following formula:
Calculation for example:
Nominal output
quantity (kg/min)
=
Forward speed
(km/h)
x
Working
width (m)
x
Application
rate (kg/ha)
600
8 km/h x 18 m x 300 kg/ha
= 72 kg/min
600
NOTICE
Constant fertiliser application is only possible at an even forward speed.
Example: a 10 % increased speed results in 10 % underfertilisation.
