Lettuce Productivity and Environmental Performance in Decoupled Aquaponics Experiments

Three experiments with four lettuce cultivars compare crop productivity and environmental impacts across decoupled aquaponics, hydroponics, and coupled aquaponics systems. The dataset, authored by Oliver Körner and last updated in May 2026, includes results from treatments with controlled macronutrient imbalances and a life cycle assessment. Environmental performance is evaluated for functional units of 1 kg fresh lettuce across impact categories like fossil resource scarcity and water consumption.

Use Cases

• Compare crop biomass production based on nutrient regimes in different soilless farming systems.
• Assess environmental impacts like fossil resource scarcity and water consumption based on life cycle assessment results.
• Investigate cultivar-specific responses to nutrient constraints based on experimental treatments.
• Model regional environmental performance for controlled environment agriculture based on scenario analysis for Central and Southern Europe.

Strengths

• Includes data from three distinct experiments with four lettuce cultivars.
• Life cycle assessment evaluates multiple environmental impact categories, including fossil resource scarcity and water consumption.
• Treatments include benchmark, nutrient-deficient, and P-limited scenarios for direct comparison.
• Regional scenario analysis covers temperate Central Europe and Mediterranean Southern Europe.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is small at 725.2 KB, indicating limited scope.
