Problem statement: The impacts of soil compaction on crop yields have been studied extensively by soil scientists due to declining soi l productivity associated with mechanisation. However, a relationship between machine-induced soil compaction and oil palm ( Elaeis guineensis ) yield is unclear. Therefore, the objectives of this study were to determine the effects of mechanizati on on soil physical properties and the influence on oi l palm yield. Approach: The palms were planted in Bernam series soil which is clay textured. Compacti on treatments were imposed for 6 consecutive years. Comparisons were made between the effects of soil compaction caused by different trailer weights and monthly transportation frequency. Results: The results showed a beneficial effect of soil compaction on the oil palm yield. It significantly increased the yield with increased mean soil bulk density. The transportation frequency played a grea ter role than the trailer weight. After six years o f soil compaction, there was a positive relationship between mean soil bulk density, porosity and oil palm yield. Conclusion: Thus compaction may not often be a problem. |
