Ammonium Sulfate

I have a customer that insists on an ammonium sulfate app because it was reccomended by the extension office. I am trying to sell her on a compost app to go with it and a C/T and molasses app.

Ive used urea spread lightly under compost with good results but never ammonium sulfate. They reccommended 5lbs per K so I was going to half that to help to keep the fert burn down.

Also should I still be able to apply the C/T and molasses? This wont cause more burn when involving the ammonium sulfate in the mix will it?

It might end up just an ammonium sulfate, C/T, and molasses app. Would this cause any burn?

Depends on the salt content of your compost... if it is low, it will help the 21-0-0

Soil pH is high-ish, so is the compost. Salt content of compost is 1.1 dS/m.

terra, you applied urea, why are you up tight about the AS?

AS is basically the same as the urea except with sulfur

sulfur is a necessary secondary/macro plant nutrient. plus your soil is alk?

Ive never spread ammonium sulfate under compost before. Wasnt really sure about how the evaporative gases would deal with being locked in by the compost. Then watering which will speed up the dissolving and releasing of gasses maybe compounding the issue.

I guess I am being more paranoid then I need to be. It is on 38K of turf so that could be a pricey replacment process.

Yes this property is alkaline, this is my second alky this spring.

Seems like all extension services are stuck in the agricultural mind set. All the recomendations I see here in CT are old farmer tricks. Everybody wants 10-10-10. The cheapest crap fert they can get their hands on. Recomended by people with phd's at the end of their name!!

My recommendation to clients who insist they need synthetic N is take the recommended rate and reduce it by 2/3.

Urea is a lot more volatile than AS , AS under or over compost should not be a issue. No way would I apply 5lbsK of AS unless you want to be mowing twice a week.
