The idea of 64th AMSTERDAM International Conference on Plant Nutrition, Soil Pollution & Wastewater Management (PNSPWM-26) scheduled on July 6-8, 2026 Amsterdam (Netherlands) is for the researchers, scientists, scholars, engineers and parctitioners from all around the world to present and share ongoing research activities. This conference provides opportunities for the delegates to exchange new ideas and application experiences face to face, to establish business or research relations and to find global partners for future collaboration. The conference is being organized by Dignified Researchers Publication (DiRPUB) operating under Pilares D'Elegancia LDA.

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)
