Compost accelerator

I know this is an old thread, but my advice on using urine as a compost accelerator is to use neat when the compost pile is quite damp, also if it's a wet compost pile, mix in some scrunched up newspaper or shredded cardboard/paper along with neat urine, on a slightly damp to dry pile add 50/50 urine to water, how often you use it depends on how active ie. heat generating your compost pile is, if you think it is starting to smell mix in cardboard/newspaper and wet with water
