Nitrogen and phosphorus losses from a feedlot for suckler cows	2002	15	.pdf	application/pdf	8601	460	76	In this area, the concentrations of NH4-N and TN in percolation water were as high as those which Yang and Lorimor (2000) report- ed in surface runoff from an American concrete feedlot (380 beef animals per 2.3 ha): 108 mg NH4-N l–1 and 177 mg TN l–1. Soil sampling and analyses Soil samples were taken to measure nitrogen leaching into deeper soil layers and to analyse phosphorus content in the soil surface.	cache/afs-5735.pdf	txt/afs-5735.txt
