Research ArticleOpen accessIn the abstractEffects 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 · 814 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis of Areas Susceptible to Gullies in Ideato South Local Government Area of Nigeria Using Geographic Information System and Remote Sensing TechnologySylvanus IroGully erosion is a critical environmental hazard in Southeastern Nigeria, threatening agricultural productivity, infrastructure, and communal safety. This study provides a spatially explicit assessment of gully erosion susceptibility in Ideato South Local Government Area (LGA), Imo State, using an integrated Geographic Information System (GIS) and Remote Sensing framework. The methodology employed a multi-criteria decision-making approach, utilizing the Analytical Hierarchy Process … …American Journal of Environmental Sciences, Vol. 22, Issue 1 · 20 Jul 2026 · 1,198 accessesView PDFCite
Research ArticleOpen accessIn the abstractMonitoring of Vegetation Degradation in various Landscapes of the Moyinkum Desert, KazakhstanOmirzhan Taukebayev, Bektemir Osmonali, Salavat Duisenbayev et al.This study is devoted to assessing the degree of vegetation degradation in various landscapes of the Moyinkum Desert, taking into account the taxonomic diversity of flora, the structure of phytocenoses, and the agrochemical condition of soils. The aim of the work was to identify areas with signs of disturbance and to analyse the factors determining degradation processes. It was established … …OnLine Journal of Biological Sciences, Vol. 26, Issue 2 · 17 Jul 2026 · 857 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 · 1,344 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 · 1,604 accessesView PDFCite
Research ArticleOpen accessIn the abstractHydro-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 · 2,752 accessesView PDFCite
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 · 5,945 accessesView PDFCite
Research ArticleOpen accessIn the abstractRotational 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 accessIn the abstractEffects of Soil Storage at Freezing Temperatures on Soil Enzymatic ActivitiesAinsley Lougheed, Kabwe NkongoloSoil enzyme activities are good indicators of soil health. It has been hypothesized that soil storage before analysis might affect microbial function. The objective of the present study was to determine if soil storage at -20 and -80°C affects soil enzymatic activities. Soil samples were collected and stored for four weeks at -20 and -80°C. Activities of nine enzymes were … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 3 · 12 Aug 2024 · 4,990 accessesView PDFCite
Research ArticleOpen accessIn the abstractLevels of Metals and Microbial Biomass in Cobalt Coleman Mine Tailings (Canada) Three Decades after Land ReclamationKabwe Nkongolo, Graeme Spiers et al.Investigations of restored metal contaminated tailings in Canada with regard to their long-term ability to sustain plant and associated microbiological populations are limited. The specific objectives of the present study were to assess (1) The current levels of total and bioavailable metals and (2) Microbial biomass in Cobalt Coleman mine tailings reclaimed in 1990.
