Litterfall Nutrient Content in Fertilized Amazon Plots, 2017-2019

Environmental Information Data Centre provides leaf nutrient data from a fertilized old-growth forest in the Central Amazon. The dataset contains realized concentrations of carbon, nitrogen, phosphorus, potassium, magnesium, calcium, manganese, zinc, hemicellulose, cellulose, and lignin, collected during a full factorial nutrient addition experiment across 2017, 2018, and 2019.

Use Cases

• Analyze the effect of nitrogen and phosphorus fertilization treatments on leaf nutrient concentrations like carbon and lignin.
• Model relationships between macronutrients (potassium, magnesium, calcium) and structural components (hemicellulose, cellulose) in litterfall.
• Assess temporal changes in micronutrient levels (manganese, zinc) across three consecutive years of fieldwork.
• Investigate correlations between nutrient addition treatments and the percentage composition of lignin in leaf litter.

Strengths

• Data collected from a controlled, full factorial nutrient addition experiment (nitrogen, phosphorus, cation treatments).
• Includes multiple nutrient and structural measurements: 6 nutrients in grams, 2 in milligrams, and 3 structural percentages.
• Fieldwork spans three consecutive years (2017, 2018, 2019), providing temporal depth.

Limitations

• Sample size and row count are unknown, limiting assessment of statistical power.
• Geographic scope is limited to a single old-growth forest site in the Central Amazon.
