Abstract
Abstract It has been discovered that evolving of offensive stench from the accumulation of droppings in fowl houses is substantially eliminated by means of coarse powders of dried ferrous sulfate hepta-hydrate. The powder is preferably used in the form of a mixture with some fly ash or dried fine powders of zeolite for the ease of dusting, and generation of the offensive odor is substantially inhibited by dusting the floor of fowl houses with said powder in advance. The thus treated droppings can be effectively utilized as an excellent fertilizer or feedstuff for fowl, fish and domestic animals.
