Question about JD fertilizer + pre m

Hey guys,
the JD LS fertilizer + pre m (13/0/3) says to apply 1.92lbs per sq ft for cool season grass. This would only be about .25LB nitrogen per 1000sq ft. I don't get why they say to apply at that ratio for cool season grass. Is it because the pre M ? Pretty sure the Pre-M is dimension.
Thanks

I cant seem to find the label for that on the JD website to take a batter look at it. If I had to guess it has something to do with the new laws that don't allow anything more than .9lb/s per 1K. .25 does sound on the weak side.

BTW check your PM and voicemail. I left you a message with my number. I would love to go take a look at that lawn soon.

OK sounds good.
That is why I am confused. The guy said it covers around 12k sq ft, but at that 2lb/1000 sq ft, 50lb bag covers 25k sq ft. The thing might be the pre-m, since it says its dimension, 15%

The Dimension will be more like 0.15%, not 15%. The rate is calculated based on how much active ingredient per acre you are trying to apply. AI/A The bag should have recommendations for AI/A based on your situation.

I have to ask, do you have an applicators license?

It could be a formula designed for a warm season grass. Bermuda is not fully out of dormancy. The main concern is crabgrass--no need to fertilize dormant Bermuda.

No bermuda here in MD. It is 99% cool season tall fescue here. I dont think JD/Lesco in this area offers anything formulated for anything other than cool season grass but I could be wrong.

I do believe he just got it if I read one of his posts in another thread correctly.

You will want to put that down at a a higher rate than 2 lbs of material per 1000 sq. ft. At that rate you would only get a rate of .12 lbs.AI/Acre. That is only half of the light end of the range. In your area, unless you are going to do two apps of the pre emergent, I would go with a better rate of like .40lbs.AI/Acre. With that analysis of fertilizer you would want to put down around 6.8 lbs. of that fertilizer per 1000 sq. ft or roughly 6 bag per acre.

Thanks John. Why would the bag say 1.92lb per 1000 sq ft? And the employee told me 4lb per 1000 sq ft? 6.8 seems right to get.9lb/1000 sq ft
