Research ArticleOpen accessIn the abstractEfficiency of Nitrogen Fixation by Rhizobium Strains Associated With White Clover in the Ecuadorian Highlands Biological Nitrogen Fixation by White Clover in EcuadorDaniela Michell Chuquimarca Mamarandi, Venancio Saúl Arahana Bonilla, Paulina Andrea Cevallos Hidalgo et al.The objective of this research was to evaluate the nitrogen-fixing capacity of 30 strains of Rhizobium isolated from white clover nodules, collected in the provinces of Pichincha and Cotopaxi under greenhouse conditions. After isolation of the bacteria and authentication of the isolates, a greenhouse experiment was conducted, in a Completely Randomized Design (CRD), with three replications and two controls: with … …OnLine Journal of Biological Sciences, Vol. 26, Issue 4 · 4 Oct 2026 · 835 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 abstractExploring the Impact of Incorporating Fine-Grained Materials on the Resistance Characteristics of Cement-Reinforced ClaySayed Amirhossein Hosseini Chaleshtori, Mohammad Alibabaei ShahrakiThis study, conducted with meticulous attention to detail, examined the influence of fine-grained materials on the resistance components of clay, with and without cement reinforcement. Micro-silica, perlite, crystal barite, gypsum, silica and talc were added to investigate this matter and samples were created and modeled under standard laboratory conditions. The current study aimed to examine the effectiveness of organic granules … …American Journal of Engineering and Applied Sciences, Vol. 17, Issue 3 · 13 Aug 2024 · 5,579 accessesView PDF Cite
