Research ArticleOpen accessPhrase in the titleMANGANESE SPECIATION IN SELECTED AGRICULTURAL SOILS OF PENINSULAR MALAYSIAJ. Habibah, J. Khairiah, B.S. Ismail, M.D. KadderiManganese speciation in selected agricultural soils of Peninsular Malaysia is discussed in this study. Manganese concentration in the Easily Leacheable and Ion Exchangeable (ELFE), Acid Reducible (AR), Organic Oxidizable (OO) and Resistant (RR) fractions of soils developed on weathered rocks, soils of mixed nature, alluvium and peat deposits are described. The total manganese concentration in soils developed on weathered rocks … …American Journal of Environmental Sciences, Vol. 10, Issue 2 · 7 Apr 2014 · 7,493 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleCOMPARING 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 · 7,487 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDynamics of Mobile Phosphorus and Potassium in the Soils of Agricultural Lands of Kostanay RegionAlmabek Nugmanov, Aliya Yskak, Tatiana Paramonova et al.Soil phosphorus deficiency is a growing constraint on crop productivity in the agricultural lands of the Kostanay Region, Republic of Kazakhstan, yet systematic data on the spatial dynamics of mobile phosphorus and potassium across soil types remain limited. This study assessed the availability of mobile forms of phosphorus and potassium, alongside key physicochemical properties, including soil pH and cation exchange … …OnLine Journal of Biological Sciences, Vol. 26, Issue 1 · 14 Apr 2026 · 1,594 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPyritization of the Coastal Sediments in the Kelantan Plains in the Malay Peninsula during the HoloceneM.S.K. Enio, J. Shamshuddin, C.I. Fauziah, M.H.A. HusniProblem statement: For a number of geological reasons a proportion of the present coastal plains in the Malay Peninsula were inundated by seawater in the past when pyrite in some of the soils is believed to have been mineralized. Random survey of these sites showed a unique distribution and depth of pyritic layer in the soils along the coastal plains. … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 3 · 16 Aug 2011 · 8,740 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhosphorus Availability Modulates Bradyrhizobium japonicum’s Impact on Soil Micribial Biomass and Soybean (Glycine max (L.) Merrill) Yield in Lubumbashi Tropical SoilsBen Tshibuyi Kasu-Bandi et al.Tropical soils in sub-Saharan Africa exhibit low fertility, high acidity, and limited Phosphorus (P) availability, a key nutrient for agricultural productivity and the sustainability of cropping systems. This deficiency, exacerbated by the strong fixation of P in acidic soils, not only limits plant growth but also the efficiency of the nitrogen-fixing symbiosis between soybeans (Glycine max (L.) Merrill) and Bradyrhizobium … …American Journal of Agricultural and Biological Sciences, Vol. 21, Issue 1 · 13 May 2026 · 1,980 accessesView PDFCite
Research ArticleOpen accessIn the abstractImpact of Agritechnologies on the Biomass and Nutritional Parameters of Crops: A Study of Corn, Soybean, and Pea in Southeast KazakhstanGulvira Yessenbayeva, Aruzhan Ilyas, Serik Kenenbayev et al.The study investigates the impact of various agritechnologies on the biomass and nutritional parameters of corn, soybean, and winter pea cultivated in Southeast Kazakhstan. This research is particularly relevant given the significant challenges facing agriculture in Kazakhstan, including soil degradation, reduced arable land, and the need for sustainable farming practices. Organic and traditional farming methods were evaluated for their effectiveness … …OnLine Journal of Biological Sciences, Vol. 25, Issue 4 · 16 Feb 2026 · 1,600 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnhancing Corn Yield and Soil Fertility in Light Chestnut Soils Using BioEcoGum: A Case Study from KazakhstanKuanysh Karabayev, Kanat Kulymbet, Ashirali Smanov, Gulbira AtashevaThis study evaluates the efficacy of the biological fertilizer BioEcoGum on corn yield and soil fertility under temperate climatic conditions at Karasai, Kazakhstan. The aim of this study was to assess the agronomic, soil, and economic effects of BioEcoGum application on corn (Zea mays L.) cultivated on light chestnut soils in southeastern Kazakhstan. A randomized block design was used, incorporating … …OnLine Journal of Biological Sciences, Vol. 25, Issue 4 · 9 Jan 2026 · 2,516 accessesView PDFCite
Research ArticleOpen accessIn the abstractProbe-based Semi-permanent Soil Humidity SensorSoobin Jeon, Dongmahn SeoThe modern agricultural environment has the problems of an aging rural population and a decreasing rural labor population. Recently, smart farms based on information and communication technology have been studied to address environmental issues in agriculture. The smart farm consists of three parts: a data collection unit, a processing unit, and a control unit. Among them, the data collection unit … …Journal of Computer Science, Vol. 21, Issue 10 · 16 Dec 2025 · 1,923 accessesView PDFCite

The experiment was conducted in the agricultural experimental Station Zarechnoye limited liability partnership with southern thin chernozem soils. Records and observations of the growth and development of sunflowers were … …OnLine Journal of Biological Sciences, Vol. 23, Issue 3 · 23 May 2023 · 5,254 accessesView PDFCite
Research ArticleOpen accessIn the abstractBaseline Concentrations of 11 Elements as a Function of Land uses in Surface Soils of the Katangese Copperbelt Area (D.R. Congo)Martin T. Mpinda, Tresor N. Kisimba, Theodore M. Mwamba et al.The Katangese Copperbelt Area (KCA) located south-eastern of D.R. Congo presents high concentration of Metal Trace Elements (MTE) due to a rich natural geochemical background and intense mining activities. However, the lack of data on specific baseline concentrations makes it difficult to assess and monitor the environmental quality of soils in the region. In this study, 11 MTE were measured … …American Journal of Environmental Sciences, Vol. 17, Issue 6 · 3 Jan 2022 · 7,126 accessesView PDFCite
