American society frequently faces difficult choices between environmental protection and other interests such as economic development and community welfare . Since ammonia exists naturally and is also present in cleaning products , exposure may occur from these sources . Because of the risk of compaction and a high likelihood of ammonia loss ( due to poor soil coverage after application ) , the best strategy for nitrogen application is to wait until conditions are workable to avoid soil damage and significant nitrogen loss . k. Records in the system may be disclosed to the President 's Foreign Intelligence Advisory Board , and the Intelligence Oversight Board , and any successor organizations , when requested by those entities , or when the Inspector General determines that disclosure will assist in the performance of their oversight functions . Recent improvements in sewage treatment have decreased ammonia concentrations downstream from many urban areas by converting the ammonia to nitrate .
