The Effect of Intercropping on Soil Structure Attributes and Soil Erosion on Sloping Land
Soil erosion problems in Malaysia have been recognized for a long time. However, management of upland area that is more exposed to soil erosion and soil degradation risk through introduction of different cropping systems is still largely unknown. Consequently, the current knowledge of rates of so...

| description | Soil erosion problems in Malaysia have been recognized for a long time. However,
management of upland area that is more exposed to soil erosion and soil
degradation risk through introduction of different cropping systems is still largely
unknown. Consequently, the current knowledge of rates of soil loss on upland
slopes is very limited. Therefore, the objectives of this study were to evaluate the
effect of intercropping on soil structure attributes and soil erosion, and to evaluate
effect of slope position on structural attributes and soil erosion.
Two experiments of intercropping of banana and pineapple and intercropping of
immature rubber with banana and pineapple consisting of standard erosion plot and
on farm research respectively were carried out for 40 months. In the first
experiment, four standard erosion plots of slopes 9% and length 22.1 m were
prepared. Plot sizes were 22.1 x 2.5 m, 22.1 x 5.0 m, 22.1 x 5.0 m, and 22.1 x 2.5
m for bare plot, banana plot, banana-pineapple intercropped plot, and pineapple plot, respectively. In the second experiment a farmer's field of an area 11 ,250 m2
of intercropping was selected. The slope varied from 9-15%. Both experiments
focused on evaluating some soil properties that were closely related to soil
structure such as bulk density, soil aggregate stability, soil organic matter, runoff,
and soil loss. The effect of root biomass on the above properties was also
evaluated. |
