Ammonium Sulphamate

I understand that Ammonium Sulphamate is used as a compost activator. Does anyone know which products in particular contain this? The only activators I've found have been described as "organic" and have been made up of other substances.

I know it is banned as a herbicide in the EU, don't worry - I'm not trying to get it for this purpose. I have a lot of compost that needs help and the natural stuff just isn't cutting it.

Thank you in advance!



Sulphate of ammonia fertiliser is freely available, even Tesco sells it, and that will do the job. If the green content of your heap is lower than it should be, then something like Garotta compost activator instead will be helpful.

sulphamate is a different compound to sulphate.
if you want to activate your compost have you considered the old fashioned activator of human urine.

I had a look at the RHS page on compost heaps - they mention using sulphate of ammonia fertiliser and/or garotta, rather than ammonium sulphamate. Sorry, I assumed you'd made a typing mistake or something, didn't think you really meant ammonium sulphamate.

I thought that but asked a passing chemist on the way to his lab. its a salt made using sulphamate acid. Never heard of it let alone used it.

Doesn't sound like something that might be of use in a compost pile, does it, sbg.
