Through nature’s alchemy, the buried, decayed remains of a fish are reborn as peas, radishes, carrots and other fresh vegetables. Bacteria decompose proteins in the carcass, forming ammonia, a chemical consisting of nitrogen and hydrogen. Plants must have nitrogen, but plants cannot use it in the form of ammonia. Other kinds of soil bacteria convert ammonia into usable nitrate. Burying fish remains in the soil of the artist's garden helps recycle nitrogen and honors the fish that feeds his family.
