Homemade Boom Sprayer Calibration Help
We just bought a 50 gallon, Wylie ATV spot sprayer. I built a boom for it, and I modeled it after an old spray rig we have. Robbed some nozzles off of it, and kept the same spacing & height off the ground. The boom fits the reciever hitch on my mule, and is 7' wide. Pics to come....
here's the specs:
5 Nozzles @ 20" Spacing
20" above grade
Governed the mule to 7mph (a little fast IMO)
Appication rate: 18 GPA
Acres per tank: 2.7 (50 gal / 18 gpa)
I used this chart to calibrate it: http://ohioline.osu.edu/aex-fact/0520.html
I measured off 204', and clocked the time it took to travel the distance (19 seconds). Then captured a sample from each nozzle for 19 seconds. All nozzles caught 18 oz's.
Here is my question.....Are my calculations correct?
The herbicide I want to use has an application rate of 2 pints per acre.
So I take 2.7 ac/tk x 2 pts/ac = 5.4 pts/tk
So i need 5.4 pints of chemical
Does this check out?
Im trying to keep it simple, but I feel like im missing something.
