Research ArticleOpen accessEvery word in the titleCurrent State of Haplic Chernozems in Specially Protected Natural Areas of the Steppe ZoneSaglara S. Mandzhieva, Lyudmila Yu. Goncharova, Abdulmalik A. Batukaev et al.The current ecological state of Haplic Chernozems has been studied in three Specially Protected Natural Areas (SPNAs) of the Steppe zone in South of Russia. It has been found that the content of organic matter, texture and elements content of soils depend on the period and conditions of reservation in the SPNA. In accordance with the content and reserve of … …OnLine Journal of Biological Sciences, Vol. 17, Issue 4 · 13 Dec 2017 · 7,357 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRotational Pasture Management for Ameliorating Productivity and Feed Value of Vegetation, Soil Quality, and Sustainability in Dry Steppe ZoneGani Stybayev, Meisam Zargar, Beibit Nasiyev et al.Over the past years, a farming system in the Akmola region of Kazakhstan has undergone significant changes: The average number of animals per farm and the use of external inputs have significantly enhanced while the diversity of farming practices has decreased, becoming similar to intensive farming. In this research, we evaluated the rotational pastures for increasing the productivity and feed … …OnLine Journal of Biological Sciences, Vol. 25, Issue 1 · 18 Jan 2025 · 4,264 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Effect of Differentiated Nitrogen Fertilization using Satellite Navigation Systems on the Spring Wheat (Triticum aestivum L.) Crop Yield in the Conditions of Chernozem-Like Soils in the Northern Forest Steppe of the Tyumen Region of RussiaAltynay Oxukbayeva, Nikolai Abramov, Marden Baidalin, Sergei SemizorovSoil cultivation without layers turnover impeded the process of nitrate nitrogen accumulation compared with plowing. The traditional scheme of mineral fertilization applying the averaged standard did not create a heterogeneous level of nutrient supply in primary soil cultivation systems. These factors set them in unequal conditions by default in terms of nitrogen supply to crops. Solid mineral fertilization with the … …OnLine Journal of Biological Sciences, Vol. 23, Issue 1 · 16 Jan 2023 · 5,203 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePasture Productivity Depending on the Method of Pasture use in the Steppe Zone of Northern KazakhstanBalzhan Akhylbekova, Nurlan Serekpayev, Adilbek Nogayev, Bakhytbek ZhumabekUnsystematic grazing of animals and continuous use of pastures leads to their degradation and, accordingly, to a shortage of pasture forage for the production of competitive environmentally friendly livestock products. The proportion of productive grasses in grass covers is decreasing; therefore, there is an urgent need to preserve valuable plant species in pasture grass, restore the productivity of natural vegetation … …OnLine Journal of Biological Sciences, Vol. 22, Issue 4 · 3 Nov 2022 · 5,913 accessesView PDFCite
InvestigationOpen accessEvery word in the titleDeveloping a System of Organic Farming Technologies to Obtain Environmentally Clean Agricultural Products (Organic Food) in the Steppe Zone of the Kostanai RegionAlmabek Batyrzhanovich Nugmanov, Yuriy Valerievich Tulayev, Saniya Abiltaevna Tulkubayeva, Svetlana Vladimirovna SomovaThe goal of the research is to study the opportunity to produce environmentally clean agricultural products (organic food) under the conditions of the Kostanai Region. The researches were made in two crop rotations: cereal laying fallow, two-field crop rotation (1 – biologized fallow – mustard, 2 – wheat) and cereal laying fallow, two-field crop rotation (1 – biologized fallow – … …OnLine Journal of Biological Sciences, Vol. 18, Issue 2 · 23 Dec 2017 · 7,393 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCHEMICAL EQUILIBRIUM OF SOIL SOLUTION IN STEPPE ZONE SOILA. A. Batukaev, A. P. Endovitsky, T. M. Minkina et al.Dynamics of material composition, migration and accumulation of salts is determined by chemical equilibrium in soil solution. Soil solution contains associated electrically neutral ion pairs CaCO30; CaSO40, MgCO30, MgSO40, charged ion pairs CaHCO3+, MgHCO3+, NaCO3-, NaSO4-, CaOH+, MgOH+. Calculation method is proposed for quantitative assessment of real ion forms in the soil solution of chestnut solonetz soil complex.

This study investigated the species composition and ecological distribution of lichens in Burabay State National Nature Park, northern Kazakhstan. Established in 2000, the park encompasses over 100,000 hectares representing a unique forest-steppe ecotone surrounded by extensive steppe landscapes, supporting approximately … …OnLine Journal of Biological Sciences, Vol. 25, Issue 4 · 16 Feb 2026 · 1,833 accessesView PDFCite
Research ArticleOpen accessIn the keywordsFree Vibration Analysis of a Cross-Ply Laminated Composite Beam on Pasternak FoundationR. A. Jafari-Talookolaei, M. T. AhmadianIn this study, free vibration analysis of a cross-ply laminated composite beam (LCB) on Pasternak foundation was investigated. Natural frequencies of beam on Pasternak foundation are computed using finite element method (FEM) on the basis of Timoshenko beam theory. Effect of both shear deformation and rotary inertia are implemented in the modeling of stiffness and mass matrices.
