Abstract
Poultry wastes are posing serious environmental pollution problems in Nigeria through offensive odours and promotion of fly and rodent breeding. Farmers normally dispose of their poultry wastes through heaping and burning or dumping on the farm in the fresh state. Experiments were conducted to stabilize the waste for 12 weeks by a bag process similar to static pile composting either singly or amended with sawdust or leaves. Sawdust seems to be ideal for the production of a well stabilized product which is environmentally safe. However, even the raw waste or leaf amended waste if kept for 8 to 12 weeks produced a product which has no adverse effect on the maize yield when applied at 20 tonnes/hectare. The soils were improved through organic matter and retention of plant nutrients.
