Research ArticleOpen accessEvery word in the titleAssessing of Soil Compaction and Relations to Soil Fertility on Different Land Used in Bintulu, SarawakAizul Azfar Zulkeefli, Md. Suzauddula, Md. Rezaul Karim et al.Assessing land uses-induced changes in soil properties from natural forests to farmland are indispensable for addressing the complications in terms of agricultural landscape sustainability. A study was conducted in Rehabilitated Forest (RF), Oil Palm (OP), Secondary Forest (SF) and Rubber Plantation (RP) at University Putra Malaysia in order to examine the results of soil densification on soil characteristics and fertility … …American Journal of Applied Sciences, Vol. 17, Issue 1 · 11 Jan 2021 · 7,428 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCompaction Properties of Silty Soils in Relation to Soil Texture, Moisture Content and Organic MatterPrathuang Usaborisut, Jettapol AmpanmaneeSoil compaction is recognized as an increasingly challenging problem with regard to root growth and yield reduction in agricultural production in Thailand. The aim of this research was to study the effect of soil texture, moisture content and organic matter on the compaction properties of silty soils. Three soils with different silt contents were studied-loam, silty clay loam and silt … …American Journal of Agricultural and Biological Sciences, Vol. 10, Issue 4 · 31 Dec 2015 · 9,536 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAssessment of Soil Compaction under Center Pivot Irrigation Systems and its Effect on Crop PerformanceKhalid Ali Al-GaadiA field study on two 12.5 ha plots cultivated with wheat and alfalfa was conducted to determine Soil Compaction (SC), its spatial variability and its effect on crop performance under center pivot irrigation systems. Considering compaction at two tested soil depths, results revealed that the soil of the alfalfa plot exhibited significantly (p<0.01 and p<0.05 for 0 to 10 cm … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 1 · 12 Mar 2013 · 7,715 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEmploying Electromagnetic Induction Technique for the Assessment of Soil CompactionKhalid A. Al-GaadiAn experiment on a sandy soil field was conducted to investigate the potential of determining soil compaction from apparent soil Electrical Conductivity (ECa) measured by Electromagnetic Induction (EMI) technique. A soil conductivity meter (EM38) was used to measure ECa under four soil Moisture Contents (MC) (4.965.336.94 and 8.0%) and a range of Soil Compaction (SC) levels (on the average, from … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 4 · 7 Nov 2012 · 8,253 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSoil Compaction in Sugarcane Fields Induced by MechanizationPrathuang Usaborisut, Watcharachan SukcharoenvipharatProblem statement: Recently in Thailand, the problem of soil compaction, especially associated with more mechanized sugarcane production, has drawn attention from both the government and private sectors. Approach: To understand this problem, investigations of soil compaction using cone penetration resistance and bulk density were conducted in 16 sugarcane fields with 10 fields involving mechanized farming and 6 field's mainly manual … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 3 · 14 Sep 2011 · 8,404 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffects of Machine-Induced Soil Compaction on Growth and Yield of SugarcanePrathuang Usaborisut, Tanya NiyamapaProblem statement: Sugarcane is one of the main economic crops in Thailand. After planting, it can be harvested annually for several successive ratoon crops. Recently, soil compaction due to mechanization has been recognized as a serious problem in sugarcane production. Therefore, this study aimed to clarify the effects of soil compaction on the growth and yield of sugarcane. Approach: The … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 3 · 30 Sep 2010 · 8,706 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSoil 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 PDFCite
Research ArticleOpen accessEvery word in the titleMachinery 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 PDFCite
Research ArticleOpen accessEvery word in the titleDevelopment of Criteria for Slab Compaction of Laboratory Roller Compactor (Turamesin)R. Muniandy, F.M. Jakarni, S. Hassim, A.R. MahmudLaboratory experiments should simulate to a high degree the conditions in the field, especially in term of compaction procedures. Presently available laboratory compaction methods do not seem to be able to produce specimens that can truly represent the mixtures as it exists in the field, especially for Stone Mastic Asphalt (SMA) mixtures. SMA is highly dependent on the method of … …American Journal of Applied Sciences, Vol. 4, Issue 11 · 30 Nov 2007 · 7,118 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPores 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 PDFCite
