Here's how I figured mine.

I measured a 20 x 25 area in my parking lot and marked the corners with paint 9so I can re-use it). This is 500 sq/ft. I put some water in my tank, set my pressure and selected a nozzle and then timed how long it took me to cover that area 2x. I then used the same nozzle/pressure and sprayed into a bucket for that amount of time and measured it. Whatever it came up to was my gross quantity per 1,000 sq/ft.

In my case, it takes me 60 seconds +/1 to cover 1,000 sq/ft and I have my nozzle and pressure adjusted to 3GPM so I'm applying 3 gross gallons per 1,000 sq/ft. The fert/chem that I'm applying comes out to about 3 oz per thousand combined so I can safely call it 3 gallons of carrier per 1,000.

Make sense?

It will be based on how fast you move, which nozzle you've selected and what pressure you're spraying at.
