ABSTRACT: Manure samples were collected by floor scrapings in animal stables from Beijing suburbs. Total nitrogen (TN), total phosphorus (TP), and total potassium (TK) were analyzed by conventional wet chemical methods. All manures showed a high variability in nutrient contents. Nutrients contents in different animal manures were significantly different. TN and TK contents in layer manures were higher than swine and dairy manures (p
