Research ArticleOpen accessIn the abstractDetecting Hornbeam Trees Phenological Characteristics of Mountain ForestSasan Babaei Kafaki, Asadollah Mataji, Seyed Armin HashemiProblem statement: Phenology is the study of the seasonal occurrence of developmental or life cycle events, such as bud break, flowering, or autumn leaf drop. The proposed study attempted to quantify changes in Carpinus betulus L. phenology of deciduous broad leaf forest between the years 2003-2006. Approach: Phenological studies were fulfilled during four years as from January 2003-December 2006 by … …American Journal of Environmental Sciences, Vol. 5, Issue 5 · 31 Oct 2009 · 7,278 accessesView PDF Cite

Research ArticleOpen accessIn the abstractUptake and Translocation of Iron by Native Tree Species In A Constructed Wetland Treating Landfill LeachatesA. Snow, A. E. Ghaly, R. Cote, A.M. SnowA surface flow wetland was constructed in the Burnside Industrial Park, Dartmouth, Nova Scotia, to treat stormwater runoff from the surrounding watersheds which are comprised primarily of commercial properties and two former landfills. The objectives of this study were: (a) to compare the uptake of iron by red maple, white birch and red spruce trees growing under flooded soil conditions … …American Journal of Applied Sciences, Vol. 5, Issue 9 · 30 Sep 2009 · 6,870 accessesView PDF Cite

Research ArticleOpen accessIn the abstractLong-term Effect of Conventional and No-Tillage Production Systems on Nitrous Oxide Fluxes from Corn (Zea mays L.) Field in Southwestern QuebecAbdirashid Elmi, Bano Mehdi, Chandra Madramootoo et al.Problem statement: There is a growing trend in the adoption of conservation tillage as an alternative to conventional tillage farming system. Implications of this agricultural management shift with respect to nitrous oxide (N2O) emission, which has been a topic of intense research for the past few decades, is not yet completely understood. Approach: This study was conducted on a 2.4 … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 7,021 accessesView PDF Cite

Research ArticleOpen accessIn the abstractUptake and Translocation of Manganese by Native Tree Species in a Constructed Wetland Treating Landfill LeachatesA. Snow, A.E. GhalyA surface flow constructed wetland was used to treat stormwater runoff from surrounding watersheds which are comprised primarily of commercial properties and two former landfills. The uptake of manganese by red maple, white birch and red spruce trees growing under flooded soil conditions in the constructed wetland was compared to that of the same trees growing under well drained soil … …OnLine Journal of Biological Sciences, Vol. 7, Issue 1 · 31 Dec 2007 · 7,507 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAssessment of The Biological Integrity of The Native Vegetative Community In A Surface Flow Constructed Wetland Treating Industrial Park ContaminantsC. C. Galbrand, A. M. Snow, Abdel E. Ghaly, R. CôtéA study was conducted to evaluate the biological integrity of a constructed wetland receiving landfill leachate and stormwater runoff from the Burnside Industrial Park, Dartmouth, Nova Scotia. The biological integrity of the constructed wetland was tested in the second growing season using vegetative community monitoring. The metrics analyzed were species diversity, species heterogeneity (dominance) and exotic/invasive species abundance. There was … …OnLine Journal of Biological Sciences, Vol. 7, Issue 1 · 31 Dec 2007 · 7,002 accessesView PDF Cite

Research ArticleOpen accessIn the abstractObservational Study of Wind Shear in Northeastern BrazilFernando R. Martins, André R. Gonçalves, Enio B. PereiraThe wind energy share is growing fast in Brazil and a better understanding of wind speed vertical profiles is essential for accurate power density estimates. The wind shear is highly variable in space and time, being influenced by surface layer stability. Studies concerning wind vertical profiles may have a significant contribution to the Brazilian energy sector. However, wind observational data … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 3 · 12 Mar 2016 · 8,219 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSELF-INCOMPATIBILITY AND EFFECT OF RECIPROCAL CROSS AND OPEN POLLINATION ON FRUIT SET AND FRUIT CHARACTERISTIC IN JORDANIAN ALMOND LANDRACESS. J. OwaisLimited studies were carried out to identify self- and cross-compatibility relationships among Jordanian almond landraces. Therefore, this study aimed at studying the level of self-incompatibility and the effect of cross and open pollination on fruit set and shell, nut and kernel related traits in almond. To achieve this objective, field experiments were carried out during 2012 and 2013 cropping season … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 3 · 30 Aug 2014 · 7,386 accessesView PDF Cite

Research ArticleOpen accessIn the abstractCOMPARING GIBBS ENERGY RELATIONSHIPS FOR AMMONIA VOLATILIZATIONS FROM AGRICULTURAL SOILS FOR POTATO PRODUCTIONGuodong Liu, Yuncong Li, Ashok AlvaSoil drought, that can be enhanced by global warming increases ammonia (NH3) volatilization. This laboratory study was conducted with two soils: Krome Gravelly Loam (KGL) from Florida and Warden Silt Loam (WSL) from Washington State and two fertilizers: Ammonium sulfate [(NH4)2SO4] or ammonium nitrate (NH4NO3). Two water regimes including 20 and 80% Field Capacity (FC) were used at 20°C which … …American Journal of Environmental Sciences, Vol. 10, Issue 1 · 8 Feb 2014 · 7,493 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEFFECT OF POLYETHYLENE BLACK PLASTIC MULCH ON GROWTH AND YIELD OF TWO SUMMER VEGETABLE CROPS UNDER RAIN-FED CONDITIONS UNDER SEMI-ARID REGION CONDITIONSAtif Y. MahadeenWater use efficiency in agriculture can be enhanced by several strategies mainly by reducing evaporation from the soil surface. The mulching techniques were being used widely in irrigated crop production worldwide. The mulching techniques can be also implemented in summer vegetables production under rain-fed conditions. The current study aimed at evaluating the effect of polyethylene black plastic mulch on growth … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 2 · 29 Jan 2014 · 9,010 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAssessment of the Maize (Zea mays)-Mucuna (Mucuna deeringianum Bort) AgroecosystemCarlos Ernesto Aguilar-Jimenez, Alfredo Tolon-Becerra, Xavier Lastra-BravoProblem statement: In Selva de Chiapas, Mexico, the traditional farming technique of slash-fell-burn used on hillside fields has caused severe soil deterioration. Consequently, indigenous farmers reacted by developing several agroecological practices that improve the physical, chemical and biological fertility of the soils. Standing out among these techniques is the use of Mucuna (Mucuna deeringianum Bort.) in rotation with maize (Zea … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 2 · 30 Mar 2012 · 7,990 accessesView PDF Cite
