Water pollution, especially eutrophication, has become a serious world-wide problem in recent years. On the other hand, forage is in short supply during the dry season in Asia (especially in Southeast Asia). The purpose of this paper is to describe the development of new forage resources from among aquatic plants. In conclusion, it is suggested that three emergent plants (Zizania latifolia Turcz., Pontederia cordata L., Paspalum distichum L.) are useful as new forage species because of their absorptive ability for nitrogen and phosphorus from eutrophic water and their superior feeding value following ensiling.

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.
