Key findings

• All nutrient concentrations decreased with depth to 150mm in all treatments, when both sampling dates were analysed together.
• Direct drilling with stubble retention contributed a greater proportion of particulate P and N to TP (Total P) and TN (Total N) in surface runoff than either of the burnt systems.
• Particulate P accounted for 75%, 67%, and 83% of TP in surface runoff from the CCb, DDb, and DDr treatments, respectively.
