Nitrogen And Phosphorus Losses In Runoff On Beef Production Systems, Marta Alfaro, F. J. Salazar, N. G. Teuber, S. P. Iraira, L. A. Ramirez
IGC Proceedings (1997-2023)
In West Europe countries between 37 and 82% of the nitrogen (N) and between 27 and 38% of the phosphorus (P) reaching water sources come from agriculture and a strong correlation between the number of animals per area unit and N and P contribution to waters has been shown (Issermann, 1990). There are few data about the environmental impact of beef production systems in Southern Chile. The objective of this experiment was to quantify N and P losses in runoff (surface and subsurface) with two different stocking rates in Southern Chile.
