Potential effects of nitrogen-fertilization scenarios in small watersheds in southern Ontario



Potential effects of nitrogen-fertilization scenarios in small watersheds in southern Ontario



Proceedings of the Fourth International Conference on Precision Agriculture, St Paul, Minnesota, USA, 19-22 July 1998 Part A and Part B: 1395-1407



An integrated model such as the Environment-Policy Integrated Climate (EPIC) can be used to assess the potential economic and environmental consequences of site-specific nitrogen fertilizer application. This application of EPIC is tested for four small watersheds (280 to 380 ha) in southern Ontario, under intensive cropping dominated by soyabeans, maize and winter wheat, and various tillage systems.
