[Title] Paying Attention to Dietary Cation-Anion Balance Can Mean More Milk and Fewer Metabolic Problems [1] PDF (410 KB) [Date] May 1, 2009 [ID] 404-131 [Author(s)] Charles C. Stallings [Summary] 
Nitrogen (N) and phosphorus (P) are the two nutrients that cause the most concern with respect to environmental pollution from animal manure. Generally, higher concentrations of N and P in the ration result in their greater excretion in urine (N) and feces (N and P). Overfeeding these nutrients can be a significant problem, particularly if nutrient levels accumulate in the soil and contaminate water sources through leaching or surface runoff. Nitrogen can also volatilize as ammonia and pose a potential environmental problem with air emission standards, which are currently under review.
