An apparatus is disclosed for applying a chemical, such as an ammonia control chemical, in an animal house. The apparatus includes spreading apparatus adapted to be installed at an elevated position in the animal house and adapted for spreading the chemical onto the floor in the house. The apparatus also includes feeding apparatus adapted for feeding the chemical from a supply to the spreading apparatus. A method of controlling ammonia emissions from an animal agriculture operation includes applying an ammonia control chemical during both the early part and the late part of the grow out of the animals so that the chemical contacts ammonia from animal waste and reduces or prevents its emission into the air.

1. A method of controlling ammonia emissions from an animal agriculture operation which is the production of chickens in a chicken house, the method comprising: applying dry granules of an ammonia control chemical comprising alkali metal bisulfate have an average diameter from 0.3 mm to 1 mm during both the early part and the late part of the grow out of the chickens so that the chemical contacts ammonia from chicken waste and reduces or prevents its emission into the air;wherein the ammonia control chemical is applied by feeding the granules from a granule supply to an elevated position above the chickens, and at the elevated position spreading the granules so that they drop onto litter on a floor of the chicken house and are spread over an area of the floor. 2. The method of claim 1 wherein the ammonia control chemical is applied from above cages in the chicken house holding the chickens, through the cages, down onto the floor. 3. The method of claim 1 wherein applying the ammonia control chemical includes spreading it over an area of at least 1,000 square feet. 4. The method of claim 1 wherein applying the ammonia control chemical includes spreading it from a spreader apparatus a distance of at least 20 feet. 5. The method of claim 1 wherein the ammonia control chemical is applied during at least 60% of the days of the grow out period. 6. The method of claim 1 wherein the alkali metal bisulfate is applied in an amount within a range of from 80 to 1000 pounds per application day. 7. A method of controlling ammonia emissions from an animal agriculture operation which is the production of chickens in a chicken house, the method comprising: applying dry granules of an ammonia control chemical comprising metal bisulfate during both the early part and the late part of the grow out of the chickens so that the chemical contacts ammonia from chicken waste and reduces or prevents its emission into the air;wherein the ammonia control chemical is applied by feeding the granules from a granule supply to an elevated position above the chickens, and at the elevated position spreading the granules so that they drop onto litter on a floor of the chicken house and are spread over an area of the floor. 8. The method of claim 7 wherein the ammonia control chemical is applied to keep the ammonia level below 25 ppm. 9. The method of claim 7 wherein applying the ammonia control chemical includes spreading it over an area of at least 1,000 square feet. 10. The method of claim 7 wherein applying the ammonia control chemical includes spreading it from a spreader apparatus a distance of at least 20 feet. 11. The method of claim 7 wherein the ammonia control chemical is applied during at least 60% of the days of the grow out period. 12. A method of controlling ammonia emissions from an animal agriculture operation which is the production of poultry in a poultry house, the method comprising: applying dry granules of an ammonia control chemical comprising alkali metal bisulfate have an average diameter from 0.3 mm to 1 mm during both the early part and the late part of the grow out of the poultry so that the chemical contacts ammonia from poultry waste and reduces or prevents its emission into the air;wherein the ammonia control chemical is applied by feeding the granules from a granule supply to an elevated position above the poultry, and at the elevated position spreading the granules so that they drop onto a floor of the poultry house and are spread over an area of the floor. 13. The method of claim 12 wherein the ammonia control chemical is applied onto litter on the floor. 14. The method of claim 12 wherein the ammonia control chemical is applied to keep the ammonia level below 25 ppm. 15. The method of claim 12 wherein the ammonia control chemical is applied during at least 60% of the days of the grow out period. 16. The method of claim 12 wherein the ammonia control chemical is applied in an amount within a range of from 80 to 1000 pounds per application day.
