Level 4: Data Summaries

Key Findings

The amount of leaching that occured from the site varied depending on the soil texture. The findings conclude that N loss through leaching and runoff below the root zone are no higher in irrigated sugarcane production than in rain-fed production systems. If high yields are not achieved, the potential N losses to the environment may be high, although the dominant pathway of these losses (runoff, leaching or denitrification) may be site-specific. Improved irrigation management could help reduce N losses but, with the exception of N lost from runoff in coarse textured soil.
