| The computer model GLEAMS (Groundwater Leaching Effects of Agricultural Management Systems) was used to predict the effects of management practices on runoff and agrochemical movement under sugar cane in Mauritius. Weather, soil and management data for four sites from different climatic zones, collected during the period 1990 to 1999, were used. Preliminary model calibration was satisfactory for runoff, erosion and fertilizer losses, but unsatisfactory for pesticide loss. Annual runoff was predicted to represent less than 5 percent of total rainfall, with erosion much lower than the tolerable limit of 11 t ha-1 year-1. This modelling exercise has also indicated that fertilizers are lost predominantly in the sediment form while herbicides are mainly lost through runoff. Trash blanketing has been shown to be a viable strategy for pollution control since it reduces fertilizer and herbicide losses. | |
