Research ArticleOpen accessEvery word in the titlePossibilities of Stabilizing Soil Biological Activity by Treating Seeds With a Biological Preparation Based on Phosphate Mobilizing Bacteria in the Conditions of the Aral Sea Region of KazakhstanZhanar Zhumadilova, Laura Tokhetova, Shorabayev Yerik et al.This study examined the effect of Phosphate-Mobilizing Bacteria (PMB) as a pre-sowing treatment for forage crop seeds. The objective was to assess the potential of these bacterial biopreparations to improve both crop productivity and soil fertility. Research methods included agrochemical, microbiological, and conventional field analyses. The findings revealed that pre-sowing seed treatment with PMB increased crop yields by 7.4% to … …OnLine Journal of Biological Sciences, Vol. 26, Issue 4 · 24 Sep 2026 · 642 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleImpact 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 PDFCite
Research ArticleOpen accessEvery word in the titleEffects of Maize Potato Intercropping and Different Fertilization Methods on Rhizosphere Soil Microorganisms and Yield of PotatoHuanjin Ma, Shengguang Xu et al.A field experiment with three replicates was conducted to explore the effects of maize-potato intercropping and different nitrogen application strategies on rhizosphere soil microorganisms and potato yield. Microbial community analysis was based on relative abundance. Maize-potato intercropping improves land use efficiency, yet how differentiated nitrogen management regulates rhizosphere microecology and potato productivity in this system remains unclear. Clarifying nitrogen-mediated shifts … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 3 · 14 Sep 2026 · 790 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePhosphorus 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 accessEvery word in the titleMechanism of Garden Aquatic Plants in the Remediation of Heavy Metal-Contaminated SoilChen Chen, Guangwu LiuHeavy metals such as cadmium, lead, and mercury are resistant to microbial degradation in soil and persist for extended periods. They can bioaccumulate through the food chain, ultimately impacting human health. This study demonstrates that a combined restoration approach involving soil enhancement and garden aquatic plants, specifically through the application of ferrous sulfate, results in increased dry weight and plant … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 1 · 20 Apr 2026 · 1,497 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 accessEvery word in the titleHydrophysical 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

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 accessEvery word in the titleProbe-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
Research ArticleOpen accessEvery word in the titleHydro-Mechanical Constraints and Deformations in Road Embankments Using Unsaturated Low-Swelling SoilSoumaïla Gandema, Marcel Bawindsom Kébré, Rimyalegdo Kiébré et al.In this paper, we present the results of a simulation of the evolution of stresses and deformations in a road embankment using unsaturated low-swelling soil under hydro-mechanical pressures, modeled with the finite element code Code_Bright. We assume that this embankment, which supports asphalt, follows the Barcelona Thermo-Elasto-Plastic model (BBM-TEP). This model describes the Thermo-Hydro-Mechanical (THM) behavior of unsaturated fine soils … …American Journal of Applied Sciences, Vol. 22, Issue 1 · 16 Nov 2025 · 2,741 accessesView PDFCite
