A study was carried out in a papaya field at MARDI station, Serdang on land with slopes of 1-2 degrees. The amounts of sediment accumulated at the end of the plot were measured. The sediment or eroded soil was sampled to determine the nutrient content and bulk density. The objective of this study was to identifY and test several soil erosion control measures. An investigation of field soil erosion features indicated that fast-flowing water from uphill played a prominent role in causing soil erosion. Surface soil was also easily eroded through raindrop detachment. A large number ofsoil erosion features such as rills, flow pathways and soil pedestals were observed. The rate of erosion was drastically reduced by oil palm fronds placed across the slope and grass hedges planted across the slope. This was caused by the diversion and reduction of the water velocity flowing down the slope.
