This table clearly demonstrated the effectiveness of Jutemaster in erosion control. When the soil was bare, soil erosion increased with slope gradients and rainfall intensity. Massive erosion occurred under high rainfall intensity. On the other hand, when protected by Jutemaster, hardly any soil erosion occurred.
