Call for papers/Topics



Full Articles/ Reviews/ Shorts Papers/ Abstracts are welcomed in the following research fields:



1. Plant Nutrition



Focuses on the chemical elements necessary for plant growth and the mechanisms by which they are acquired.





  • Essential Nutrients & Classification





    • Criteria for essentiality (Arnon & Stout)




    • Macronutrients (Primary): Nitrogen (N), Phosphorus (P), Potassium (K)




    • Macronutrients (Secondary): Calcium (Ca), Magnesium (Mg), Sulfur (S)




    • Micronutrients (Trace Elements): Iron (Fe), Zinc (Zn), Manganese (Mn), Copper (Cu), Boron (B), Molybdenum (Mo), Chlorine (Cl), Nickel (Ni)






  • Nutrient Uptake Mechanisms





    • Passive transport (Diffusion, Mass flow)




    • Active transport (Ion channels, Carriers, ATP-pumps)




    • Role of the Rhizosphere and Root hairs






  • Physiological Roles & Deficiency Symptoms





    • Metabolic functions (Photosynthesis, Enzyme activation, Protein synthesis)




    • Visual symptoms (Chlorosis, Necrosis, Stunting, Anthocyanin accumulation)




    • Nutrient mobility within the plant (Mobile vs. Immobile elements)






  • Fertilizers and Soil Amendments





    • Chemical (Inorganic) fertilizers: NPK ratios, slow-release formulas




    • Organic manures: Compost, Green manure, Vermicompost




    • Bio-fertilizers: Nitrogen-fixing bacteria (Rhizobium), Mycorrhizae (VAM)







2. Soil Pollution



Examines the degradation of soil quality due to toxic substances and human activity.





  • Sources and Types of Soil Pollutants





    • Agricultural: Pesticides, Herbicides, excess Fertilizers




    • Industrial: Heavy metals (Lead, Mercury, Cadmium, Arsenic), Chemical spills




    • Urban/Domestic: Plastic waste, E-waste, Sewage sludge




    • Radioactive: Nuclear waste, Mining tailings






  • Pollutant Behavior in Soil





    • Adsorption and Desorption (Soil-water interface)




    • Leaching and Groundwater contamination




    • Bioaccumulation and Biomagnification in the food chain






  • Environmental & Health Impacts





    • Reduction in soil fertility and microbial activity




    • Phytotoxicity (toxic effects on plants)




    • Impacts on human health (Carcinogenesis, Organ failure)






  • Soil Remediation Techniques





    • Physical/Chemical: Soil washing, Excavation, Thermal treatment




    • Bioremediation: Using microorganisms to degrade organic pollutants




    • Phytoremediation: Using plants to extract or stabilize contaminants (Phytoextraction, Phytostabilization)







3. Wastewater Management



Deals with the collection, treatment, and disposal of used water to protect ecosystems.





  • Sources and Characteristics of Wastewater





    • Domestic sewage (Greywater and Blackwater)




    • Industrial effluent (Toxic chemicals, Acids, Heavy metals)




    • Agricultural runoff (Nutrient-rich, Pesticide-laden water)




    • Parameters: BOD (Biochemical Oxygen Demand), COD (Chemical Oxygen Demand), pH, Turbidity






  • Stages of Wastewater Treatment





    • Preliminary Treatment: Screening, Grit removal




    • Primary Treatment: Sedimentation and Flocculation (Physical removal of solids)




    • Secondary Treatment: Biological processes (Activated sludge, Trickling filters, Oxidation ponds)




    • Tertiary (Advanced) Treatment: Nutrient removal (Nitrogen/Phosphorus), Disinfection (Chlorination, UV, Ozonation)






  • Sustainable Wastewater Solutions





    • Constructed Wetlands and Bio-swales




    • Water Reclamation and Reuse (Irrigation, Industrial cooling)




    • Sludge Management: Anaerobic digestion, Composting, Biogas production






  • Environmental Policy and Quality Standards





    • Effluent discharge limits




    • The Clean Water Act and local regulatory frameworks




    • Impact of untreated discharge: Eutrophication and Hypoxia (Dead zones)
