Poultry manure, properly han-dled, is the most valuable of all manures produced by live-stock. It has historically been used as a source of plant nutrients and as a soil amendment. However, in areas of intense poultry produc-tion, overfertilization of pasture land with poultry manure occurs.The result is suspected ground water and surface water problemsas excess nutrients run off the land or leach into ground water supplies.

To obtain maximum economic value of plant nutrients in poultry manure and to protect our water supplies from excessive nutrient runoff or leaching, poultry manure should be applied to match nutri-ent needs of crops.
