Effects of plot length and soil texture on runoff and sediment yield occurring on machine-trafficked soils in a mixed deciduous forest

Table 4 Mean (± Std. error) of runoff, sediment yield, and runoff coefficient on different plot lengths (i.e., 2, 5, 10, 20, 30, and 40 m) and soil textures (clay and loam). Different letters indicate significant differences at P < 0.05
