A red sludge-like deposit was found in several tile systems in Florida citrus groves. This deposit prevented the tile from functioning properly by blocking the passageway through which water entered the title. The deposit was found to be due primarily to “iron bacteria” which oxidize and precipitate reduced iron in the drainage water. Chemical analyses indicated a large proportion of the material was organic—probably bacterial cell bodies and waste products. The inorganic portion was mainly hydrated iron and aluminum oxides. Bacteriological studies of the material indicated the following genera of bacteria were responsible for the formation of the deposits:
