Research ArticleOpen accessEvery word in the titleDetermination of Draft Force for a 3-bottom Disc Plough Under Sandy Loam Soil ConditionsPaul Okoko, Emmanuel A. AjavThis study was performed to determine the draft force for a 3-bottom disc plough under sandy loam soil conditions. The experiments were conducted using five different tractor speeds (3.6, 5.4, 7.2, 9.0 and 10.8 kilometer per hour(km)) and three tillage depths (10, 20 and 30 centimeter(cm)) with a view to determine the actual implement speed at the different tillage depths. … …American Journal of Agricultural and Biological Sciences, Vol. 15, Issue 1 · 15 May 2020 · 7,390 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Animal Manure Application Rates on Soil Moisture Conservation at, Somali Regional State, EthiopiaTekilil WoldeThe Ethiopian economy is mainly agrarian. It employs 85% of the population and contributes 45% of the gross domestic product and 90% of the national export earnings but agriculture in Ethiopia is dominated by rainfed farming with low productivity specially dry land part of the country like Somali region. As a result, crops have severe moisture stress through their growth … …American Journal of Agricultural and Biological Sciences, Vol. 14, Issue 1 · 15 Aug 2019 · 7,748 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Soil Types on Growth, Survival and Abundance of Mangrove (Rhizophora racemosa) and Nypa Palm (Nypa fruticans) Seedlings in the Niger Delta, NigeriaAroloye O. NumbereThe invasion of nypa palm into mangrove forest is a serious problem in the Niger Delta. It is thus hypothesized that soil will influence the growth, survival and abundance of mangrove and nypa palm seedlings. The objective was to compare the growth, survival and abundance of both species in mangroves, nypa palm and farm soils (control). The seeds were planted … …American Journal of Environmental Sciences, Vol. 15, Issue 2 · 25 Apr 2019 · 8,871 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleLong Term Ageing Effect on Physical and Shear Strength Characteristics of Oil Contaminated Sandy Soils of Al-Ahmadi Field in KuwaitHumoud Melfi Aldaihani, Fahad A. Al-OtaibiSerious environmental damage was caused to Kuwait when more than 600 oil wells were set alight following the 1991 Gulf War, leading to hydrocarbon contamination and a series of ‘oil lakes’ being created in the desert. The effects of these highly damaging actions are still detectable today, 27 years later. The main contribution of this paper is that the effects … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 1 · 1 Apr 2019 · 8,065 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAssessment of Heavy Metals Contamination in Controlled and Uncontrolled Landfill Soil, Ouagadougou, Burkina FasoBambara Telado Luc, Doumounia Ali, Kohio Nièssan et al.The study was conducted to evaluate the concentrations of heavy metals in landfill soils. The soils samples were collected in some selected landfill, at Ouagadougou. Determinations of heavy metal concentrations, calculation of contamination factor and pollution load index of heavy metal in landfill soil were undertaken. The atomic absorption spectrophotometer was used to determine the concentrations of heavy metals (Cr, … …American Journal of Environmental Sciences, Vol. 16, Issue 4 · 2 Sep 2020 · 7,317 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCadmium Stress Responses in Medicinal and Oilseed Plants: Safflower as a Promising Candidate for Soil Cadmium RemediationChristos Kikis, Giorgos Thalassinos, Vasileios AntoniadisThis study investigated the growth responses of five economically important plants—chamomile (Matricaria recutita), oregano (Origanum vulgare), safflower (Carthamus tinctorius), sage (Salvia officinalis), and wormwood (Artemisia absinthium) exposed to increasing Cd levels. Over 60 days, plants were subjected to Cd concentrations of 0, 1, 2, 3, and 4 mg per pot. Growth parameters and Cd accumulation were then assessed. At the … …American Journal of Agricultural and Biological Sciences, Vol. 20, Issue 1 · 13 Nov 2025 · 3,414 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleInfluence of Bitumen Addition on Sabkha Soil Shear Strength Characteristics under Dry and Soaked ConditionsFahad A. Alotaibi, Humoud Melfi AldaihaniHigh salt content in sabkha soils means they are significantly affected by changes in water content. Dissolution of salts within sabkha soil mass decreases their shear strength upon inundation with water, resulting from the destruction of cementation bonds between soil particles. Therefore, successful improvement for these soils must be based on reducing the dissolution of sabkha salts to minimize their … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 4 · 13 Nov 2018 · 7,392 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFractionation of Organic Carbon in Arial Beel Wetland Soils of BangladeshMonera Akter Eva, Mahmudul Islam Piash, Md. Faruque Hossain, Zakia ParveenA study was conducted to determine the organic carbon fractions in the vertical sections of a benchmark wetland soil of Bangladesh (Arial Beel) and their dynamics that directly affect the biogeochemistry of soil, water and plant biomass ecosystem. Two distinctive soil series viz. Sara and Arial are characterized such as pH, moisture content, textural class, CEC, organic carbon (SOC), bulk … …American Journal of Environmental Sciences, Vol. 14, Issue 2 · 4 May 2018 · 9,139 accessesView PDFCite
