Two questions here. Does anyone have experience composting lobster shells? I have about a pound of crushed lobster shells that have been steamed, boiled, and baked. According to Rodales, lobster has a good amount of phosphorus. I want to compost it in my next 3'x3'x3' pile. Are alfalfa pellets an economical nitrogen source 'hot' enough to breakdown straw bales? Thanks.
