Key Findings

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 (burning before harvest, tillage, fertiliser and weed control) over the entire study. For the Cowley site, the soil erosion rates ranged from 11-29 t/ha for the no tillage practices, and 47-92 t/ha for the conventional cultivation. No significant difference was measured between no tillage crops with groundcover of 0, 50 and 100%. Soil erosion predominantly occurred during the wet season.
