Table 2 shows the soil loss rate under a simulated rainfall intensity
of 80 mm h−1. The highest soil loss rate (1458 ±
50.0 g m−2) occurred in the control soil, and the lowest
(532 ± 106 g m−2) occurred in the amended soil with the
highest application rate (5%). The soil loss rate significantly decreased
as the biochar application rate increased, indicating that biochar largely ameliorated soil erosion potential in highly weathered
soils.
