Research ArticleOpen accessEvery word in the titleVertical Profile of C, N, P, K and Radionuclides in Soil Collected from Highland Tea Plantation AreasZaini Hamzah, Seh Datul Riduan, Ahmad SaatProblem statement: Cameron Highlands is a well known agricultural area in Peninsular Malaysia. Long term usage of fertilizer has caused accumulation of major elemental component in the soil. This accumulation will cause enrichment of the nutrient in the catchment located at downstream of the river through runoff. Approach: Two tea plantations on the upstream with hilly condition plantation were selected … …American Journal of Applied Sciences, Vol. 8, Issue 12 · 11 Oct 2011 · 7,509 accessesView PDF Cite

All suspended solid that carried out by the river contain various kind of hazard potential to the environment. U, Th and Pb are … …American Journal of Environmental Sciences, Vol. 7, Issue 3 · 12 Jul 2011 · 7,239 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleSoil-moisture Retention Characteristics of Earth Materials in the Weathering Profile over a Porphyritic Biotite GraniteJohn Kuna RajProblem statement: Three broad morphological zones and several sub-zones were differentiated within the weathering profile based on variations in earth materials and the degree of preservation of original bedrock minerals, textures and structures. Approach: The topmost Zone I (Grade 6) is some 12 m thick and comprises completely weathered bedrock materials (mainly a stiff, clayey sand) with indistinct relict bedrock … …Current Research in Geoscience, Vol. 1, Issue 1 · 30 Jun 2010 · 9,466 accessesView PDF Cite

Research ArticleOpen accessIn the abstractImpact of Organic Ameliorants on Grey Soil FertilityAsanbay Tagaev, Amandyk Kostakov, Sabir MakhmadzhanovThe study aimed to assess the effectiveness of organic-biological ameliorants for restoring the fertility of light grey soils in the Turkestan region of Kazakhstan, which are characterised by low humus content (0.8-1.1%) and high alkalinity (pH 7.9-8.3). The field experiment was conducted on an area of 2304 m2 using four treatment options: control (variant 1 only mineral fertilisers) and three … …OnLine Journal of Biological Sciences, Vol. 26, Issue 3 · 15 Sep 2026 · 693 accessesView PDF Cite

Research ArticleOpen accessIn the abstractImportance of Soil and Mineral Characteristics in Supporting Sustainable AgricultureIda Suryani, Marliana Sjuaib Palad, Nur Fitriani et al.Soil consists of four main components: Minerals, organic matter, air, and water, which are arranged in the space to form the soil body. Inorganic minerals in the soil come from rock fragments and other primary minerals. Sustainable soil fertility is supported by the nutrient content contained in the minerals. The research objectives were: 1) to observe the physical and chemical … …OnLine Journal of Biological Sciences, Vol. 25, Issue 2 · 25 Mar 2025 · 5,938 accessesView PDF Cite

Research ArticleOpen accessIn the abstractComparative Phytochemical Analysis of Hydrodistilled Essential Oils of Scots Pine (Pinus Sylvestris L.) Needles From Central KazakhstanKuralay Tuleshova, Margarita Ishmuratova, Asanali Aynabayev et al.This study presents a detailed phytochemical investigation of hydrodistilled essential oils extracted from the needles of Pinus sylvestris (Scots pine), collected from fifteen natural populations located in the Karaganda and Ulytau regions of Central Kazakhstan. The extraction was performed using hydrodistillation with hexane as a co-solvent, and the chemical composition of the oils was subsequently analyzed using gas chromatography–mass spectrometry … …OnLine Journal of Biological Sciences, Vol. 25, Issue 4 · 28 Nov 2025 · 2,696 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAdafruit IO Based Smart Irrigation System using MQTT Protocol for Urban FarmingDevesh Mishra, Prakhar Yadav, Vandana Yadav et al.Freshwater is needed for irrigation and nutrient supply to plants to make up for the lack of rainfall. Agricultural activities consume more than 70% of the available freshwater. This emphasizes the importance of responsible management of water for irrigation using smart Internet of Things (IoT) based agricultural practices combined with irrigation-related technologies The purpose of this research article is to … …Journal of Computer Science, Vol. 18, Issue 5 · 23 May 2022 · 6,894 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffects of Root Rot in Soybean Cultivars with Diverse Susceptibility to the Disease on Plant Physiology, Yield, Amino Acids and Mycotoxins Profile in Climatic Conditions of KazakhstanNurlan Kuldybayev, Yerlan Dutbayev, Bozena Lozowicka et al.Soybean is an important high-value crop but susceptible to soil-borne diseases. A field trial was conducted in Kazakhstan to evaluate the effects of soybean cultivars and Fusarium root rot severity on soybean crop physiology, chlorophyll fractions and amino acids profile. The highest yield was achieved in 2018 (up to 4 t ha-1) for K-9648 cultivar. The greatest root rot severity … …OnLine Journal of Biological Sciences, Vol. 21, Issue 4 · 27 Dec 2021 · 6,299 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAnalysis of Non-Equilibrium Phase Change in Transfers at Low Water Content by Considering the Film FlowMarcel Bawindsom Kébré, François Ouédraogo, Bétaboalé Naon et al.In this study, we analyze the effect of non-equilibrium phase change on transfer at low water content in a sandy soil by considering the contribution of film flow in the motion of liquid water. Indeed, most of the non-equilibrium study methods use for hydraulic conductivity, the van Genuchten-Mualem (VGM) capillary model which does not consider the film flow occurred at … …American Journal of Environmental Sciences, Vol. 17, Issue 1 · 1 Jun 2021 · 6,395 accessesView PDF Cite
