EditorialOpen accessIn the abstractAn Opportunity for the Agricultural Sector: The Renewable Energy SourcesRiccardo Testa, Salvatore TudiscaToday, among the most important issue for energy decisions by policymakers, there are security challenges and environmental impacts on climate change and economic aspects. Since the seventies, in fact, global warming and environmental issues have had an increasing importance in international debate, attracting the attention of several scientific studies (Landi and Benelli, 2016). Many of these studies denoted that over … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 3 · 6 Sep 2016 · 8,092 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Fertility Status of Soils at Rehabilitated Degraded Land in Universiti Putra Malaysia Planted with Pinus caribaea and Swietenia macrophyllaMohammad Nazrin Abdul Malik, Arifin Abdu, Daljit Singh Karam et al.Soil fertility (both physical and chemical) is one of the important factors limiting plant growth. So, the fertility of the soils should be determined before growing crops and after the establishment of forest rehabilitation. A study was conducted to determine the fertility status of soils at rehabilitated degraded land in Universiti Putra Malaysia. The main objective was to compare the … …American Journal of Applied Sciences, Vol. 12, Issue 10 · 5 Nov 2015 · 7,276 accessesView PDF Cite

Research ArticleOpen accessIn the abstractStatus of Soil Microbial Population, Enzymatic Activity and Biomass of Selected Natural, Secondary and Rehabilitated ForestsK. S. Daljit Singh, A. Arifin, O. Radziah et al.Substantial clearance of forests and conversion of forest into various land use types contribute to deterioration of soil fertility and associated nutrients loss. Soils from natural and rehabilitated forest in Chikus Forest Reserve and also enrichment planting forest and secondary forest of Tapah Hill Forest Reserve, Perak, Malaysia were selected in order to assess the influence of land use change … …American Journal of Environmental Sciences, Vol. 9, Issue 4 · 28 Aug 2013 · 7,803 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAssessing Soil Fertility Status of Rehabilitated Degraded Tropical RainforestAiza Shaliha Jamaluddin, Arifin Abdu, Hazandy Abdul-Hamid et al.An assessment of forest rehabilitation program in relation to soil fertility status by using soil indices could provide fundamental information on soil suitability for species preferences and improve the effective technique for future rehabilitation program in tropical rainforests. This study was conducted in order to characterize the soil properties and identifying the soil fertility status of rehabilitated and secondary forests. … …American Journal of Environmental Sciences, Vol. 9, Issue 3 · 19 Jul 2013 · 8,457 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffects of Land Use Practices on the Organic Carbon Content, Cation Exchange Capacity and Aggregate Stability of Soils in the Catchment ZonesMosayeb Heshmati, Arifin Abdu, Shamshuddin Jusop, Nik Muhammad MajidProblem statement: Land use practice leads to changes in the physico-chemical properties of soils, such as Soil Organic Carbon (SOC), Cation Exchange Capacity (CEC) and Soil Aggregate Stability (SAS) that cause soil erosion. Approach: Merek catchment, Iran suffers from land degradation due to poor land use practice. A study was carried out with the objectives: (i) to determine soil nutrient … …American Journal of Applied Sciences, Vol. 8, Issue 12 · 25 Oct 2011 · 8,722 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAssessing Soil Biological Properties of Natural and Planted Forests in the Malaysian Tropical Lowland Dipterocarp ForestDaljit Singh Karam, Arifin Abdu, O. Radziah et al.Problem statement: A study was conducted to evaluate and compare the soil biological properties of a natural forest and an 18-year-old stand of Shorea leprosula in Chikus Forest Reserve, Perak, Malaysia. Approach: Soils were sampled at depths of 0-15 cm (topsoil) and 15-30 cm (subsoil) in six subplots (20×20 m) of natural forest (C1) and of a planted S. leprosula … …American Journal of Applied Sciences, Vol. 8, Issue 9 · 29 Jul 2011 · 7,961 accessesView PDF Cite

Research ArticleOpen accessIn the abstractComparing the Fertility of Soils under Khaya ivorensis Plantation and Regenerated Degraded Secondary ForestsYetti Heryati, Arifin Abdu, Mohd Noor Mahat et al.Problem statement: It is widely accepted that conversion of natural forest to other land use types leads to deterioration of soil fertility and increased soil compaction which consequently become degraded secondary forests. Degraded secondary forest or forestland is indicated by low in soil fertility and organic matter due to imbalance input and output from original vegetation. Forest plantation through planting … …American Journal of Applied Sciences, Vol. 8, Issue 5 · 17 May 2011 · 8,509 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffect of Tropical Peat Swamp Forest Clearing on Soil Carbon StorageAhmad Shukri Mat Nuri, Seca Gandaseca, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidAbstract: Problem Statement: Forest clearing in Tropical Peat Swamp Forest (TPSF) will affect forest soil carbon storage. Thus this study is essential to determine whether the effect of clearing of forest does to the nature of soil forest concentrating on soil carbon storage. The objectives of this study were to analyze carbon storage values in logged and clear cut TPSF … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 1 · 15 Dec 2010 · 8,939 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSelected Soil Morphological, Mineralogical and Sesquioxide Properties of Rehabilitated and Secondary ForestsB. T. Saga, O. H. Ahmed, A. S. Jamaluddin et al.Problem statement: The tropical rain forests in Southeast Asia have been characterized by several researchers. However empirical data on soil characteristics under degraded forest land in tropical rain forest and rehabilitated program are limited. A study was conducted to evaluate the soil morphology, mineralogical and sesquioxide properties of a rehabilitated degraded forest land (19 years after it was planted with … …American Journal of Environmental Sciences, Vol. 6, Issue 4 · 31 Aug 2010 · 8,016 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Importance of Maintaining a Proper Database on Forest Restoration Program for Orangutans in BorneoRaymond Alfred, Koh Pei Hue, Lee Shan Khee, Rayner AlfredProblem statement: The lowland forest of Sabah is the most important habitat for orangutans and pygmy elephants.
