LBA-ECO ND-02: Small Stem and Non-Woody Biomass in a Fertilized Secondary Forest

LBA-ECO ND-02 provides biomass measurements for grasses, herbs, vines, and dead material from a fertilization experiment in a Brazilian secondary-growth forest. Data were collected destructively from 12 treatment plots over six sampling events between 1999 and 2005. The experiment tested the effects of nitrogen, phosphorus, and combined fertilization on understory vegetation in 20m x 20m plots.

Use Cases

• Analyzing the effects of nitrogen and phosphorus fertilization on non-woody plant biomass in a secondary forest.
• Modeling nutrient limitation and biomass accumulation in regenerating tropical ecosystems.
• Comparing temporal biomass dynamics across six sampling years from 1999 to 2005.
• Studying treatment replication across three blocks with control, N, P, and N+P plots.

Strengths

• Provides a six-year time series with data from 1999, 2000, 2001, 2003, 2004, and 2005.
• Experimental design includes three replicated blocks and four distinct fertilization treatments.
• Cross-platform presence on datagov and nasa_earthdata signals established use and importance.

Limitations

• Column names and exact row/size counts are not provided in any source, limiting immediate usability.
• Metadata conflicts: the 'last updated' date differs significantly between datagov (2026) and nasa_earthdata (2005).
• License is ambiguously listed as 'other-license-specified' without details.
