Research ArticleOpen accessIn the abstractASSESSING SOIL RESPIRATION AS AN INDICATOR OF SOIL MICROBIAL ACTIVITY IN RECLAIMED METAL CONTAMINATED LANDSKassandre Goupil, Kabwe NkongoloMining, roasting as well as smelting of these elements have caused sulphur dioxide fumigations and metal particulate depositions which have led to various detrimental effects on the overall environmental quality of the Greater Sudbury region. Soil amendment and revegetation within the Greater Sudbury Region were initiated to restore the damage land. Several methods have been used to assess the progress … …American Journal of Environmental Sciences, Vol. 10, Issue 4 · 11 Jul 2014 · 8,104 accessesView PDFCite
Research ArticleOpen accessIn the abstractIMPROVING PHOSPHORUS NUTRITION OF COTTONWalter B. Gordon, Larry Murphy, Pawel WiatrakCrop recovery of applied Phosphorus (P) fertilizer can be low, especially during season of low soil temperature, which decreases plant root growth and nutrient uptake. The H2PO4- or HPO4-2 anions readily react with soil cations such as Calcium (Ca), Magnesium (Mg), iron (Fe) and Aluminum (Al) to produce various phosphate compounds of very limited water solubility. Specialty Fertilizer Products (SFP), … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 3 · 10 May 2014 · 7,112 accessesView PDFCite
Research ArticleOpen accessIn the abstractIMPROVING PHOSPHORUS NUTRITION OF CORNWalter B. Gordon, Larry Murphy, Pawel WiatrakPhosphorus (P) generally occurs in soils as the anions H2PO4- or HPO4-2 depending on soil pH. These anions readily react with soil cations such as calcium, magnesium, iron and aluminum to produce various phosphate compounds of very limited water solubility. Crop recovery of applied phosphate fertilizer can be quite low during the season of application. In addition, the large amounts … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 3 · 18 Mar 2014 · 7,447 accessesView PDFCite
Research ArticleOpen accessIn the abstractBEHAVIOR OF THE NON-SELECTIVE HERBICIDE GLYPHOSATE IN AGRICULTURAL SOILAbdul Jabbar Al-Rajab, Othman M. HakamiGlyphosate [N-phosphonomethyl]glycine is a systematic, non-selective, organophosphorus herbicide used worldwide in agriculture and industrial zones. Following its application, residues of glyphosate can threaten soil or aquatic organisms in adjacent water. In this study, we followed the degradation, stabilization, remobilization and leaching of 14C-glyphosate in three agricultural soils in laboratory incubations and in lysimeters under field conditions. Glyphosate degradation was relatively … …American Journal of Environmental Sciences, Vol. 10, Issue 2 · 15 Mar 2014 · 9,341 accessesView PDFCite
Research ArticleOpen accessIn the abstractEFFECT OF UREA WITH NUTRISPHERE-N POLYMER IN FALL AND SPRING NITROGEN APPLICATIONS FOR CORNPawel Wiatrak, Walter B. GordonPolymer coated urea may be a viable option to improve Nitrogen (N) uptake and corn (Zea mays L.) grain yields, especially in areas with relatively high soil N loss. The objective of this study was to evaluate the effect of two urea application timings (fall and spring) and three N rates (90, 180 and 270 kg N ha-1) with and … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 1 · 27 Dec 2013 · 8,153 accessesView PDFCite
Research ArticleOpen accessIn the abstractTHE GROUP COMPOSITION OF METAL COMPOUNDS IN SOIL AS AN INDEX OF SOIL ECOLOGICAL STATESaglara Sergeevna Mandzhieva, Tatiana Mikhailovna Minkina, Svetlana Nikolaevna Sushkova et al.A system of indices for assessing the soil ecological state as based upon the group composition of heavy metal compounds in soils is proposed. The group composition of heavy metal were determined using combined fractionation including sequential and parallel extractions (1 N NH4Ac, pH 8; 1% EDTA in NH4Ac and 1 N HCl). It was shown that strongly bound compounds … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 1 · 7 Dec 2013 · 7,595 accessesView PDFCite
Research ArticleOpen accessIn the abstractCadmium Exposure Via Food Crops: A Case Study of Intensive Farming AreaRaagheni Munisamy, Sharifah Norkhadijah Syed Ismail, Sarva Mangala PraveenaCadmium (Cd) is ubiquitous in environment and may enter food chain through intense application of phosphate fertilizers to agricultural crops. A cross-sectional study was conducted at Kuala Terla and Blue Valley farming villages, Cameron Highlands to determine cadmium concentration in vegetables and soil and to determine the health risks among respondents. A total of 87 respondents were selected based on … …American Journal of Applied Sciences, Vol. 10, Issue 10 · 6 Sep 2013 · 8,537 accessesView PDFCite
Research ArticleOpen accessIn the abstractLand Degradation and Preventive Measures From the Perspective of the StakeholdersMosayeb Heshmati, Arifin Abdu, Nik Muhamad Majid, J. ShamshuddinLand degradation at the catchment scale in Iran is widespread, usually assumed to be accelerated by the activities of local inhabitants. Social issues such as low income, poverty and low level of welfare and education contribute to land degradation. A study was conducted to identify the causes of land degradation in Merek catchment, Iran and to propose appropriate measures to … …American Journal of Applied Sciences, Vol. 10, Issue 9 · 24 Aug 2013 · 8,370 accessesView PDFCite

Sustainable agriculture is necessary to attain the goal of sustainable development. According to the Food and Agriculture Organization (FAO), sustainable agriculture is the successful management of resources to satisfy the changing human needs while maintaining or enhancing the quality of environment and conserving natural … …OnLine Journal of Biological Sciences, Vol. 13, Issue 2 · 5 Jul 2013 · 10,259 accessesView PDFCite
Research ArticleOpen accessIn the abstractDrying Poultry Manure for Pollution Potential Reduction and Production of Organic FertilizerA. E. Ghaly, M. AlhattabDisposal and storage of raw poultry manure has become an environmental problem because of the associated air, water and soil pollution. Poultry manure begins to decompose immediately after excretion giving off ammonia which, in high concentrations, can have adverse effects on the health and productivity of birds as well as the health of the farm workers. Application to land is … …American Journal of Environmental Sciences, Vol. 9, Issue 2 · 13 Mar 2013 · 9,731 accessesView PDFCite
