Research ArticleOpen accessEvery word in the titleTHE 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 · 7,593 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEssential Oil Chemical Composition of Myrtle Growing in Northeastern Algeria and Estimation of its Antibacterial EffectivenessBarhouchi Badra, Aouadi Saoudi, Abdi AkilaThe aim of this study is to determine the antibacterial effectiveness of leaves essential oil extracted from myrtle growing in Algeria. A cluster analysis of soil and water was effectuated for performing chemical and granulometric analyses. The essential oil was isolated from leaves by hydro distillation and analyzed by Gas Chromatography-Mass Spectrometry (GC/MS). The leaves yield reached a peak at … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 2 · 5 Apr 2016 · 8,356 accessesView PDFCite

The work aims to determine the opportunities for restoring the biological resource potential of degraded pastures using organic fertilizers based on the principles of organic farming. In the steppe zone of Northern Kazakhstan, a study of the species … …OnLine Journal of Biological Sciences, Vol. 24, Issue 4 · 3 Sep 2024 · 4,160 accessesView PDFCite
Research ArticleOpen accessIn the keywordsCurrent Growth Conditions of Populus Diversifolia Schrenk and Populus Pruinosa Schrenk in the Syr-Darya ValleyPolina Vesselova, Karina Makhmudova et al.In the context of urbanization of territories and the intensification of agriculture, the biological diversity of animals and plants in their habitats is degrading. The purpose of the study is to determine the edaphic factors affecting the growth of Populus diversifolia Schrenk and Populus pruinosa Schrenk, as well as anthropogenic factors affecting their conservation in the Syr-Darya valley (Kazakhstan). For … …OnLine Journal of Biological Sciences, Vol. 22, Issue 4 · 6 Oct 2022 · 5,542 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimisation of Plant Mineral Nutrition, Growth Stimulation and Yield Enhancement Through the Use of a Bio Formulation Based on Phosphate Solubilising BacteriaZhanar Zhumadilova, Laura Tokhetova, Gulsim Baimbetova et al.The aim of this study was to evaluate the agronomic and fodder efficiency of various fertilisation treatments in relation to their effects on plant growth, chemical composition, and soil properties. The study evaluated the effectiveness of a bio-formulation based on Phosphate-Solubilising Bacteria (PSB) in combination with mineral fertiliser (N60P90 + N30) in enhancing the productivity of forage crops and improving … …OnLine Journal of Biological Sciences, Vol. 26, Issue 3 · 23 Sep 2026 · 385 accessesView PDFCite
Research ArticleOpen accessIn the abstractChanges in the Composition and Diversity of Pasture Grass Due to the Influence of Grazing in the Steppe Zone of Northern KazakhstanAliya Baitelenova, Balzhan Akhylbekova, Meisam Zargar et al.Overgrazing poses a serious threat to the sustainability of steppe pasturelands in Northern Kazakhstan, where intensifying livestock pressure drives significant changes in vegetation composition, species diversity, and soil fertility. This study investigated the effects of grazing intensity on pasture vegetation and chestnut soil properties in the Zhaksyn district of the Akmola region. Field surveys were conducted in July-August 2024 using … …OnLine Journal of Biological Sciences, Vol. 26, Issue 1 · 31 Mar 2026 · 1,338 accessesView PDFCite
Research ArticleOpen accessIn the abstractHydrophysical Properties of Soils as Indicators of the Hydrological Role of Rudny Altai ForestsAndrey Kalachev, Tamara Burenina, Stanislav Rogovsky et al.The hydrophysical properties of soils and parent rock are key factors shaping forest hydrological functioning, as they influence multiple runoff components. This study assessed the effects of forest stand composition on soil moisture and water permeability between 2021 and 2023 in the middle mountain-taiga zone of the Rudny Altai, within the Zhuravlikha River basin, a tributary of the Irtysh River. … …OnLine Journal of Biological Sciences, Vol. 26, Issue 1 · 24 Mar 2026 · 1,316 accessesView PDFCite
