Key findings (brief)
Silburn and Glanville (2002) found that runoff, soil loss, and sediment concentration decreased with increasing cover. No traffic gave less runoff and soil loss than trafficked plots, but was less effective than cover. Cover and no traffic combined gave least runoff and soil loss. Erosion processes were strongly affected by hill-furrow geometry.
Silburn et al. (2002) observed concentrations α, β and total endosulfan in runoff decreased significantly with increasing cover, irrespective of cover type (wheat stubble or cotton trash) or placement (in furrow or overall).
Silburn and Hunter (2009) discovered that retaining surface cover and avoiding wheel traffic were both effective in reducing runoff losses of total N and P, especially when used together. Retaining cover gave considerably lower concentrations of total P, and of N and P associated with sediment, with no significant differences (P > 0.05) between wheel and non-wheel tracks.
