Research ArticleOpen accessPhrase in the titleComparison of Selected Soil Chemical Properties of Two Different Mangrove Forests in SarawakEmpi Rambok, Seca Gandaseca, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidProblem statement: Despite few studies of forest health and environmental conditions of mangrove forest in Sarawak, the data was not sufficient to facilitate baseline data and direct comparison of mangrove forest health obtained for different location of mangrove forest in Sarawak. On this regard, determination of contemporary mangrove soil condition was essential to addressing mangrove forest for forest health, carbon … …American Journal of Environmental Sciences, Vol. 6, Issue 5 · 31 Oct 2010 · 9,648 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleEffects of Converting Secondary Forest to Oil Palm Plantation on Peat Soil Carbon and Nitrogen and other Soil Chemical PropertiesMakilan Muniandy, Osumanu Haruna Ahmed, Nik Muhamad Ab. Majid, Mohd Khanif YusopProblem statement: Peatlands are natural sequesters of carbon and nitrogen. Once they are disturbed the tendency to lose carbon and nitrogen to the environment is very high. This study investigated the effect of converting peat land forest into oil palm plantation on soil chemical properties with particular emphasis on carbon and nitrogen storage. Approach: Soil samples were collected randomly at … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 7,302 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleAnalyze the Significance of Age and Height on the Physical and Chemical Properties of Ethiopian Giant Timber BambooYalew Dessalegn, Balkeshwar Singh, Aart W. van VuureThis research aims to examine the properties of culm based on the factors of age and height for structural and industrial purposes. Aged from 1-3 years old of culm and the height was divided into 3 parts which bottom, middle and top. The properties of Giant Timber bamboo in Ethiopia were not investigated so far from the other research work … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 2 · 7 May 2021 · 7,034 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleSTUDY OF PHYSICO-CHEMICAL PROPERTIES OF THE SURFACE AND GROUND WATERA.Y. Al-Ghamdi, Mohamed El-Shahate Ismaiel Saraya, A.O. Al-Ghamdi, S.A. ZabinOf all the natural resources, water is unarguably the most essential and precious. Life began in water and life is nurtured by water. Ninety seven percent of the world’s water is found in oceans. Only 2.5% of the world’s water are non-saline fresh water. Saudi Arabia is a desert country with no permanent rivers or lakes and very little rainfall. … …American Journal of Environmental Sciences, Vol. 10, Issue 3 · 18 Apr 2014 · 7,787 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleThe Dynamics of Chemical Properties and Soil Microbial Types at Agroforestry System in Supporting Environmental Friendly AgricultureIda Suryani, Sulfiana, Maimuna Nontji, MarlianaAgroforestry is described as the land-use system producing and conserving various agricultural, livestock, and fishery commodities combined with forestry commodities. The research aims to determine the chemical properties of the soil and types of microbial (especially the presence of soil bacterial) in the cocoa farming system. The two types of analysis were conducted: (1) Soil chemical properties included pH, C-organic, … …OnLine Journal of Biological Sciences, Vol. 22, Issue 3 · 16 Aug 2022 · 5,409 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleEffects of Bradyrhizobium japonicum on Some Chemical Properties of Ferralsols under Soybean (Glycine max (L.) Merr.) CultivationBen Tshibuyi Kasu-Bandi, Laurent Kidinda Kidinda, Germain Nyembo Kasendue et al.This study was conducted on acidic soils in two different agro-ecological zones in order to evaluate the influence of Bradyrhizobium japonicum on soil chemical properties in the Upper-Katanga (DR Congo). A split plot design with three replicates was installed in two sites. The main plots included three strains of Bradyrhizobium japonicum plus the untreated control and four soybean varieties in … …American Journal of Agricultural and Biological Sciences, Vol. 14, Issue 1 · 17 Oct 2019 · 7,618 accessesView PDFCite
