Cropping Area (ha)
Required nitrogen rate (kg/ha)

APPLICATION EQUIPMENT
Fill in the fields below to compare your potential application speed with Big N or Urea.
Width (m)	Big N	Airseeder
Speed (km/hr)	Big N	Airseeder
Capacities (t)	Big N tank	Urea Bin

Hours worked per day

DOWN TIME
Fill in the fields below to see which fertiliser will give you the greatest overall application efficiency.
Fertiliser delivery to tractor (minutes *)	Big N Big N delivered direct to you	Urea
Manoeuvering, hose coupling #(minutes)	Big N	Urea
Transfer (min/t)	Big N	Urea
* How long does it take to get from the field to the silo and back? Divide this by the number of times you can fill your applicator before you need to do it again. # Time spent coupling hoses and maneovering rig to nurse tank or urea truck.
