Research ArticleOpen accessIn the abstractSustainable Technology for Agriculture at Extreme Altitudes: Design and Evaluation of a Sprinkler Irrigation System in a Peruvian High Andean CommunityJuan Eduardo Suarez Rivadeneira, Freddy A. Manayay, Daniel Olivier Carranza Lizana et al.In high-altitude agroecosystems, erratic rainfall patterns and steep topography severely constrain crop productivity by exposing plants to soil water deficits during critical phenological stages. This study aimed to enhance the productivity of eleven staple and horticultural crops corn (Zea mays), tomato (Solanum lycopersicum), cucumber (Cucumis sativus), eggplant (Solanum melongena), lettuce (Lactuca sativa), carrot (Daucus carota), barley (Hordeum vulgare), celery (Apium … …OnLine Journal of Biological Sciences, Vol. 26, Issue 4 · 2 Oct 2026 · 663 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 · 5,945 accessesView PDF Cite

Research ArticleOpen accessIn the abstractBacterial Diversity and Community Structure Characteristics in Rhizosphere Soil of Coconut (Cocos nucifera L.) under Intercropping PineappleLilan Lu, Hui Zhu, Yingying Liu et al.To explore the bacterial diversity and community structure characteristics of the rhizosphere soil of fruit type coconuts of different varieties under the intercropping pineapple model, the Illumina high throughput sequencing technology was used to detect the composition and diversity of soil microorganisms. Furthermore, the correlation between the physical and chemical properties of soil and the characteristics of the rhizosphere soil … …American Journal of Biochemistry and Biotechnology, Vol. 19, Issue 1 · 16 Feb 2023 · 5,751 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDetection of Rust Emergence in Coffee Plantations using Data Mining: A Systematic ReviewLenin Quiñones Huatangari, Candy Lisbeth Ocaña Zúñiga, Annick Estefany Huaccha Castillo et al.Hemileia vastatrix is a fungus that causes coffee rust disease and, depending on the level of severity, reduces the photosynthetic capacity of the plant and of new shoots, leading to low coffee yields and even death; its symptoms are visible on the leaf. Systems based on computer algorithms have been developed to predict diseases and pests in coffee. The objective … …OnLine Journal of Biological Sciences, Vol. 22, Issue 2 · 31 Mar 2022 · 8,028 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Effects of Cement Kiln Dust on the Soil Electrical ResistivityHamid Ranjkesh Adarmanabadi, Arezou Rasti, Mehrdad RazaviElectrical resistivity is a non-destructive, cost-effective and sensitive method to evaluate soil's physical and chemical properties. Electrical resistivity has been used widely in surface and subsurface exploration. The electrical resistivity is directly related to the subsurface geotechnical and geothermal properties like porosity, temperature, salinity and water content. Recently uses of waste material as an additive to improve the soil engineering … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 1 · 14 Jan 2021 · 7,279 accessesView PDF Cite
