Research ArticleOpen accessPhrase in the titleComparing 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 accessPhrase in the titleGrowth Performance and Biomass Accumulation of a Khaya ivorensis Plantation in three Soil Series of UltisolsYetti Heryati, Debora Belawan, Arifin Abdu et al.Abstract: Problem statement: There was no information about the relationship between growth parameters, such as diameter and height and tree component biomass of Khaya ivorensis plantations with different soil types. The objectives of this study were, first, to determine and compare the growth of K. ivorensis in three different (Padang Besar, Durian and Rengam) soil series of Ultisols and, second, … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 1 · 15 Dec 2010 · 10,170 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsAssessing Forest Plantation Productivity of Exotic and Indigenous Species on Degraded Secondary ForestsYetti Heryati, Arifin Abdu, Mohd Noor Mahat et al.Problem Statement: There is general agreement that human activities such as deforestation and land use change to other land use types have contributed to degraded secondary forests or forestland and increases the emission of greenhouse gases which ultimately led to global climate change. An establishment of forest plantation in particular is regarded as an important approach for sequestering carbon. However, … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 2 · 6 Jun 2011 · 10,518 accessesView PDF Cite
