Key findings

  • Compared with grazing and forestry, sugarcane production was found to have a significant impact on riverine water quality as evidenced by higher concentrations of nitrogen, phosphorus and total suspended solids in stream-waters draining land under sugarcane;
  • Regardless of land use, concentrations of total N and P were dominated by soluble fractions, particularly in organic combination; and
  • Median values of TSS for each site were significantly positively correlated (P < 0.001) with the proportion of upstream land under sugarcane and negatively correlated with the proportion of upstream land under grazing.
