View Full Version : Question regarding lb of N / 1000 using liquid fert

I know I'm going to look like a fool to some of you, but for the life of me part of my brain can't work this out.

Here's what I'm going to use.

Green Flo 30-0-0 at a rate of 1 lb of N / 1000 sq ft.

Running it in my PG Ultra, so covering 32-34,000 sq ft / 8 gal.

How much green flow should I use???

I've been trying to pull up a label on Lesco's site, but it's not showing me, just the MSDS. That doesn't really help me out with this question.

Thanks.

Nobody is a fool who is trying to learn something... Question? Does the label say how much N is in each gallon? If so, divide 128 by the number of #N to determine the # of oz. to get 1# N. I.e., if there are 3# N per gallon then it will take 42.67 oz. 1000/ sq ft to apply 1# N. (128 oz div. by 3 = 42.67 oz). The weight per gallon would do also knowing that 30% of each gallon is N, you could do some quick math to figure how much to use to get 1# 1000/sq ft. To minimze overlap stripes you may want to cut your delivery rate to 1/2#N per trip and make 2 trips across the lawn in opposite directions (north, south then east west) Make sense? Neal

There are 3.15 lbs of N per gallon.

A gallon weighs 10.5 lbs.

Try to think of a 5 gallon case as being the same as a 52.5 lb bag.

To answer the question, use 40.6 oz per 1000 for 1 lb of N.

Access the label from here since not every package size has the label link. This one does:

I would venture a guess that your PeraGreen can't get 40 oz down on 1000 sq ft even if you didn't dilute it with water. And you must or clogging is inevitable. I would select another method of application.

Tremor -

You're right, I can't get down 40 / 1000, but I could get down 30 / 1000. The label recommends anywhere from 1/4 lb N - 1 lb N, so if I had to run it straight, I could.

I realize that granular will be more cost effective, since I'll be running 6-8 gallons @ $10 / gallon per tank full, but there's been so much rain lately I'm starting to get VERY backed up and am looking at trying to save some time by not having to run the parking lots, streets, etc., and cleaning up if I overshoot with the granular.

For some reason I can't pull those labels up on Lesco's site.

It just sends me back to the "home page" of whatever product I'm looking at, where it lists the price, quantity available at the local service center, etc.

The MSDS will come up, not the label.

Yep, that one worked now.

I finally figured out what I was doing wrong. Can't just click on the "label" thread, gotta click on the "pdf" thread that pops up too.

i come up with 31 oz per 1000sf to get 1 pound if N

Sorry ant

You need to recheck your math Iam with Tremor 40.6 oz

I would go with 14 gals per acre times 128 = 1792 divide by 43.56 = 41 oz

Charles Cue

10.5( weight of 1 gal of fert) x .30 (% on N) = 3.15

1(pound of N)/3.15 = .317 oz

correct?

10.5( weight of 1 gal of fert) x .30 (% on N) = 3.15

1(pound of N)/3.15 = .317 oz

correct?

Why do you use weight? never did it that way

3.15 lbs n per gal times 14 gals = 44.1 lbs on in 14 gals

Charles Cue

charles.. how did you get your answer?

i was tought to go with the weight of a gal of fert.

There are 3.15 pounds of N per gallon or 128 oz. Divide oz liquid by pounds of N or 128/3.15 = 40.63 oz or one pound of N.

Maybe I shouldn't Post this. I know Tremor doesn't want any Pity, But He has late stages of MS and is pretty much confined to a wheel chair. He just had a B day and I talked to him on the phone. He has not been active as normal on E mail or Facebook. On a better note Groundskper is back working after a successful cancer operation.
