I use 48 oz. per 25 gallons of water. If you use granulated AMS and add it to the water too fast without mixing and try to use your pump it can clog the screen. I mix my 25 gallon sprayer with a 3/4" diameter wooden broom handle. Use long sleeved orange rubber gloves made for handling chemicals.
I fill mine half way then put the AMS in, close the lid, and go for a swerving joy ride up and down the nearest gravel road with my ball cap on backwards and a big stupid grin on my face. The water sloshes around and mixes the AMS. I get my jollies.
You need to get the right kind. I've used AMS to fertilize before when I wanted to add some sulfur at the same time. The kind we're talking about is the spray grade (I think that's what my bag calls it) AMS that's ether granular or liquid. I get the granular type. It's pure white like salt and dissolves quickly in water.
Powder performs better but I use liquid AMS from Rural King. While it does add sulphur to your soil in a sulfate form it can give some benefit. It’s nitrogen addition helps uptake of the plant of a herbicide like Gly. It’s real purpose tho is to allow certain herbicides like Gly to mix better w water that is hard which usually has high levels of CA and /or Mg.
In reality I’ve used and not used w little seen diff in kill. But I do use most time as w coal fired plants emitting very little sulphur in the last 20 years, rainfall is not adding sulphur to the soil.
As for crop oil... add it but ck that you’re generic Gly doesn’t already have a surfactant. If it does don’t add oil.
