Soil Water Samplers (Cup Lysimeters)

Our Soil Water Samplers use a unique porous ceramic formula that is inert to most pore water compounds in saturated and unsaturated soils and sediments.

Samplers are available in different levels of bubble point (0.5, 1 and 2 bar) and suction cup sizes for almost any practical applications, from pot or soil columns and deep installations down to 300 feet or where long lateral runs are required.

Soil Water Samplers, especially suction cup samplers (also called tension lysimeters), are widely used to extract soil pore water for chemical analysis. These tools play a crucial role in understanding solute transport, nutrient cycling, and contaminant dynamics in the soil profile. Their applications span various disciplines of science and engineering.

Environmental Science & Engineering

  • Contaminant Transport Studies:
    • Monitor nitrate, pesticide, heavy metals, and organic contaminants movement through the vadose (unsaturated) zone.
  • Site Remediation and Risk Assessment:
    • Evaluate leaching potential of pollutants from waste sites or industrial operations.
  • Landfill Monitoring:
    • Sample pore water beneath liners or covers to assess leachate migration.

Agriculture and Soil Science

  • Nutrient Leaching Studies:
    • Assess how much nitrate, phosphate, or potassium is leaching beyond the root zone.
  • Fertilizer Efficiency:
    • Optimize fertilization timing and rates by understanding nutrient mobility.
  • Irrigation Impact Analysis:
    • Investigate how irrigation practices influence water and solute movement in soil.

Hydrology and Water Resources

  • Vadose Zone Monitoring:
    • Track water movement and quality in the unsaturated zone above the groundwater table.
  • Aquifer Recharge Studies:
    • Sample deep soil water to estimate quality and potential for groundwater recharge.
  • Watershed Management:
    • Identify nonpoint source pollution from agricultural or urban runoff.

Climate Science and Biogeochemistry

  • Carbon and Nitrogen Cycling:
    • Analyze dissolved organic carbon (DOC) or nitrogen species in soil solution to understand biogeochemical cycling.
  • Greenhouse Gas Research:
    • Provide supporting data on nitrogen species related to N₂O emissions from soils.
  • Soil Solution Chemistry in Climate Experiments:
    • Support studies on how soil chemistry responds to warming, drought, or altered precipitation.

Forestry and Ecology

  • Nutrient Dynamics in Forest Ecosystems:
    • Track how nutrients and ions move through forest soils under different tree species or land-use changes.
  • Soil-Plant Interaction Studies:
    • Investigate how plant root uptake affects nutrient and solute concentrations in soil water.

Civil and Geotechnical Engineering

  • Soil-Water Interaction Studies:
    • Measure pore water composition to assess corrosivity or chemical aggressiveness in relation to underground structures or foundations.
  • Land Reclamation Projects:
    • Monitor chemical evolution of reclaimed soils, especially in post-industrial or mining areas.
