How much would I need to use for 8k sq ft. I have a 50lbs bag. Its 46% nitrogen. Need help asap.

 

[DC3]

How much nitrogen are you trying to apply per 1000FT?

 

[erdons]

46% x 1lb = .46lbs nitrogen applied for every 1lb of product and you need 1lb of nitrogen per 1000 sq ft.

4lbs of product for 1000 sq ft x 8 = 32lbs

 

[DC3]

for 8000sqft coverage: 8.7lbs for .5# 1000; 13lbs for .75# 1000; 17.4lbs for 1# 1000; 26.1lbs for 1.5# 1000

for 8000sqft coverage: 8.7lbs for .5# 1000; 13lbs for .75# 1000; 17.4lbs for 1# 1000; 26.1lbs for 1.5# 1000

[Movingshrub]

46% x 1lb = .46lbs nitrogen applied for every 1lb of product and you need 1lb of nitrogen per 1000 sq ft.

4lbs of product for 1000 sq ft x 8 = 32lbs

Assuming you want one pound of N per thousand square feet,
2.17lb of product for 1000 sq ft x 8 = 17.39lb off urea fert spread evenly over the entire 8000sqft lawn.

I do the apply before rain method and since it's a fast release type I use half the desired monthly, twice a month.

Just look at the hole in the bottom of the spreader when the stopper is open and see if the hole looks like a good size. If you think it looks good then go for it and start throwing it down.

I am serious...

If your worried and do not like my method then you should use @DC3 supplied math.

46% x 1lb = .46lbs nitrogen applied for every 1lb of product and you need 1lb of nitrogen per 1000 sq ft.

Ah doing math in my head while holding a crying baby, yes my estimate should have been around 16lbs not 32. I hope I didn't burn his lawn. 😂 😱

 

[DC3]

if the hole looks like a good size.

I prefer your method anyway. My neighbors think I'm nuts, but I always say if @wardconnor can pull it off... Why can't I!?

Right there with you on the screaming baby.

Doubt it would be burned. Bermuda loves nitrogen.

 

[Greendoc]

I have seen Bermuda take 1.5-2 lb N applications. Just feel sorry for the guy that has to mow it a week after such an application.

I typically it this way as well.

Years ago, my well meaning father-in-law put urea on my lawn while I was working and going to school and just didn't have the time. He firmly believed in the "more is better" theory. I'm certain he never did a fertilizer calculation in his life. He was a pipe fitter, not a mathematician! He put about 25 lbs on about 5000 ft. That's a little more than 2.5 lbs. N/k. He watered it in. I'm certain he thought he was helping, but I mowed and mowed and mowed. He's been dead for a number of years, but he had a pretty lawn.

Thanks. For some reason I am not getting notifications on response from this post.

I was aiming for 2lbs per 1000. My back yard has alot of bare spots and I'm trying to get it to spread. I also have a sprinkler system so I dont mind running the sprinklers.

These rates were pounds of urea fert to give you X pounds of nitrogen per 1,000 sqft.

If you want 1/2LB N per 1,000 sqft, then spread 8.7lb over the entire 8000sqft area. If you want 1.5LB of N per 1,000 sqft, spread 26.1 of fert over the 8000sqft area.

I calculated total weight required to give specific nitrogen amounts per 1000 sqft. I.e. 8000 sqft yard, for 1/2 lb of nitrogen per 1000 sqft requires 8.7 lbs of fertilizer total.

I just broke it down for each point.
