I need a little clarification
Your article about composting with kids in a soda bottle says. "a tablespoon of fertilizer, chicken manure or urine." Does that mean a tablespoon or one of those three, or a tablespoon of fertilizer and then an amount of chicken manure or urine? If it's the latter, how much? We are going to be doing this at our preschool. Thanks!
You just need to use one of them. Fertilizer is probably your best bet and a high nitrogen fertilizer works best. Have fun with the project!
