Lettuce Iodine Biofortification Data from Two-Season Fertilizer Trials

Experimental data from two growing seasons evaluating iodinated copper-based foliar fertilizers on lettuce. The dataset, authored by Anmeng Liu and last updated in March 2026, measures effects on iodine content, yield, vitamin C, nitrate, soluble sugar, and copper accumulation. Results show iodine content increases of up to 66.20-fold in shoots and yield reductions of up to 35.84% with high-concentration treatments.

Use Cases

• Modeling the relationship between iodine application rates and lettuce tissue iodine content based on reported concentration levels.
• Analyzing trade-offs between nutritional quality (e.g., vitamin C, nitrate) and crop yield under different fertilizer treatments.
• Evaluating the reduction in copper accumulation in plant tissues when using iodinated fertilizers compared to traditional Bordeaux mixture.
• Comparing the efficacy of different iodine forms and concentrations for biofortification across multiple growing seasons.

Strengths

• Data is derived from controlled experiments over two distinct growing seasons, allowing for seasonal comparison.
• Specific quantitative results are reported, such as iodine content increases of 24.71- to 66.20-fold and copper reductions of 57.6%–91.57%.
• Multiple quality metrics are measured, including vitamin C, nitrate, and soluble sugar content.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• The geographic origin and specific soil conditions of the experiment are not detailed.
