Key findings
The most consistent reduction in runoff and soil and nutrient loss with simulated rain was found in the no tillage treatments with high stubble retention.
Mean runoff as a percentage of applied rain ranged from 26 to 60% for April 1989 and August 1990 respectively for 0.5 t/ha/year stubble and 5 to 35% for 5.0 t/ha/year stubble treatments.
Mean soil loss ranged from 0.52 to 1.1 t/ha for 0.5 t/ha/year stubble and 0.03 to 0.8 t/ha for 5.0 t/ha/year stubble treatments.
