Gail Damerow in Storey's Guide to Raising Chickens says "the smell of ammonia coming from chicken manure in either the henhouse or the compost pile means nitrogen is evaporating. To reduce nitrogen losses, periodically apple ground rock phosphate or ground dolomitic limestone. Either substance combines with nitrogen to keep it from evaporating and the improve manure's fertilizer value." I'm thinking the Sweet PDZ does the same thing. I also found it at Tractor supply store>
