Are there any good places to buy Ammonium Sulfate fertilizer online?
I am having trouble finding it locally.
My PH is always high and limits nutrient absorption.
I would like to try it.
Thanks

There are some sources on ebay. That's where I buy it for FAS.

Where have you checked for it around you?

I am in Huntsville and have no issue finding Ammonium sulfate fertilizer everywhere. It's at Home Depot, Lowes, local seed & feed type stores, and my co-op. With that being said, it's usually a mixture of Ammonium Sulfate and some Urea so make it that 33-0-0 or 34-0-0 blend.

If you're looking for Ammonium Nitrate, that's going to be an entirely different story.

I buy mine at site one aka John Deere landscaping center. 50#bag for $20-25. None in your area?

FYI FWIW:

Indexed common fertilizer acidifying effects:

Sulfur coated Urea (38-0-0): 1.18
Ammonium Sulfate (21-0-0): 1.10
Urea (46-0-0): 0.81
Ammonium Nitrate (34-0-0): 0.60

Higher numbers indicate greater acidifying effect. For reference, the index of Elemental Sulfur is: 3.12. One pound of sulfur will neutralize 3.12# of 100 CCE limestone; therefor, 1# of Ammonium Sulfate (21-0-0) will neutralize 1.10 pounds of 100 CCE limestone and 5# of 21-0-0 (equal to an application of 1.05 lbs/k of N) would neutralize 5.5 lbs of 100 CCE of limestone. Theoretically, of course.

Very good info thank.
I have been to all the big box stores in my area. Lowes Homedepot Tractor Supply Walmart
I called Advanced turf solutions but didnt get an answer. I think a new guy was working.
"No we don't sale ammonia. and yes we do sale sulfure!!!"
OOOOOKayyyy :shock: :shock: :shock:
Ill try back tomorrow
But it looks like sulfur coated urea will do the job as well.

I just called Davidson co-op. The lady I spoke with said they have 50 pound bags of ammonium sulfate for $13.99.

Yes and no. The No: To get your 1# of N/k you'll apply almost 5# of 21-0-0 product for a total neutralizing effect of 5.5 vs the application of only 2.6# of 38-0-0 to get 1# of N/k for a total neutralizing effect of 3.1. The Yes: No one expects to be able to make a dent in their calciferous soil lime content, but the advantages of temporary reduction in soil solution aren't likely to be that great between the two; However, the organic acidifying component of the Sulfur in the coated urea may actually be more advantageous for duration. If that makes sense.

I just picked up 2 bags of Ammonium Sulfate(21-0-0) at Site One for around $25 a bag. I am sure there are quite a few of them around in Nashville, give them a call and see.
