Has anyone used CS in farming???

We just started organic dairy farming, and I know we can use CS, and I've looked online and have found info on farmers using it in the stocktanks for their cattle, and it helps with all sorts of things, BUT, it doesn't say how much they use, how often, etc. Just wondering if anyone has ANY idea how much to add to a stock tank??? I'm making my own, but I wish I could make a vat at a time!!! LOL :-) any input would be appreciated!
