Nature and magnitude of soil erosion in sugarcane land on the wet tropic coast of north-eastern Queensland - Mundoo

Level 1 General Description


The purpose of the study was to investigate the relationship between rainfall, management practice and sediment losses.

Methods (Brief)

The study was conducted on a commercial farm in the wet tropics within 50km of Innisfail. For each plot, measurements were taken in 2 adjacent interrows at 10 m intervals down the slope (18%) to a length slope of 6 0m. The study also recorded data on compaction, bulk density, soil moisture, particle size analysis, water-dispersible clay percentage and cation exchange capacity.

Key Findings (Brief)

Soil erosion rate ranged from 5-15 t/ha for no tillage with varied cover, compared to 47-505 t/ha for the conventional cultivation (iburning before harvest, tillage, fertiliser and weed control) over the entire study. For the Mundoo site, the soil erosion rate varied from 19-88 t/ha for the no tillage methods, and 136-505 t/ha for the conventional cultivation. No significant difference was measured between no tillage crops with groundcover of 0, 50 and 100%. Most of the annual soil erosion occurred during the monsoon wet season.
