Research ArticleOpen accessIn the keywordsOil Palm (Elaeis guineensis) Roots Response to Mechanization in Bernam Series SoilZuraidah Yahya, Aminuddin Husin, Jamal Talib et al.Problem statement: Field practices involving the use of mechanization in oil palm plantations could result in soil compaction which alters the soil physical properties. The gradual deterioration of soil physical conditions could restrict the growth and function of roots. This study was carried out to evaluate the response of oil palm roots to changes in soil physical properties due to … …American Journal of Applied Sciences, Vol. 7, Issue 3 · 31 Mar 2010 · 8,771 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsSoil Compaction and Oil Palm (Elaeis guineensis) Yield in a Clay Textured SoilZuraidah Yahya, Aminuddin Husin, Jamal Talib et al.Problem Statement: The impacts of soil compaction on crop yields have been studied extensively by soil scientists due to declining soil 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 mechanization on soil physical properties and the influence … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 1 · 31 Mar 2010 · 10,280 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPores Reconfiguration in Compacted Bernam Series SoilZuraidah Yahya, Aminuddin Husin, Jamal Talib et al.Problem statement: The introduction of mechanization in oil palm (Elaeis guineensis) plantations resulted in soil compaction with increased bulk density and reduced porosity due to reconfiguration of soil pores. This could be a serious problem in the future as soil pores are important for aeration and water movement. Approach: This study was carried out to determine the effect of mechanization … …American Journal of Applied Sciences, Vol. 8, Issue 3 · 25 Mar 2011 · 8,681 accessesView PDF Cite

Research ArticleOpen accessIn the abstractMachinery Compaction Effects on Physical Properties of Bernam Series in an Oil Palm PlantationZuraidah Yahya, Aminuddin Husin, Jamal Talib et al.Problem statement: Introduction of mechanisation in oil palm (Elaeis guineensis) plantations could result in soil compaction and cause soil degradation. This could be a serious problem in the future due to increase in size, weight and transportation frequency of machines used. Objectives: This trial was carried out to evaluate the effect of different trailer weights and transportation frequencies on the … …American Journal of Applied Sciences, Vol. 6, Issue 12 · 31 Dec 2009 · 8,081 accessesView PDF Cite
