Topics All Abstracts, Reviews, short articles, Full articles, Posters are welcomed related with any of the following research fields: 1. Soil Physical and Chemical Properties This area focuses on the fundamental "makeup" of the soil, which dictates its ability to support life. Soil Mineralogy: Crystal structure of clays, primary and secondary minerals. Soil Physics: Texture and structure (pore space and bulk density). Hydrology: Water retention, hydraulic conductivity, and infiltration. Aeration and thermal properties. Soil Chemistry: Cation Exchange Capacity (CEC) and pH regulation. Redox potential ($E_h$) in submerged soils (wetlands). Soil organic matter (SOM) fractions and humification. 2. Soil Fertility and Plant Nutrition This subfield is directly interrelated with crop production, focusing on the nutrient cycle. Macronutrients and Micronutrients: Nitrogen phosphorus, and potassium (NPK) cycles; trace element bioavailability. Fertilizer Technology: Slow-release fertilizers, foliar applications, and bio-fertilizers. Rhizosphere Dynamics: The chemical interactions between root exudates and soil particles. Nutrient Use Efficiency (NUE): Genetic and management strategies to reduce nutrient waste. 3. Soil Biology and Microbiology A rapidly growing field focused on the "living" part of the soil. The Soil Microbiome: Diversity of bacteria, fungi (Mycorrhizae), and archaea. Soil Fauna: The role of earthworms, nematodes, and micro-arthropods in nutrient cycling. Biological Nitrogen Fixation (BNF): Symbiotic relationships (e.g., Rhizobium in legumes). Soil Health Indicators: Enzyme activities and microbial biomass carbon. 4. Pedology and Soil Classification This independent branch deals with the origin and mapping of soils. Pedogenesis: Soil-forming factors (climatology, topography, parent material, time, and organisms). Soil Taxonomy: Classification systems (USDA Soil Taxonomy, World Reference Base). Digital Soil Mapping: Using GIS and remote sensing to predict soil properties across landscapes. 5. Agronomy and Crop Science The "Agriculture" side of the research, heavily dependent on soil data. Crop Physiology: Photosynthesis efficiency and stress tolerance (drought, salinity, heat). Cropping Systems: Monoculture vs. polyculture, crop rotation, and intercropping. Precision Agriculture: Use of GPS, IoT sensors, and variable rate technology (VRT). Weed and Pest Management: Integrated Pest Management (IPM) and herbicide resistance. 6. Sustainable Land Management and Ecology Interrelated topics that address environmental impact and long-term viability. Soil Conservation: Erosion control (wind and water), terracing, and cover cropping. Carbon Sequestration: Soil’s role as a carbon sink to mitigate climate change. Regenerative Agriculture: No-till farming and holistic grazing practices. Agroforestry: Integrating trees into agricultural landscapes for biodiversity. 7. Environmental Soil Science (Contamination & Remediation) Focuses on the impact of human activity on soil quality. Soil Pollution: Heavy metals, microplastics, and pesticide residues. Bioremediation and Phytoremediation: Using microbes or plants to decontaminate soil. Waste Management: Application of sewage sludge, compost, and biochar to land.
