Biosolids Characterization and Seedling Growth Data from Rio de Janeiro

Alegria, Rio de Janeiro, Brazil is the study location. This dataset describes the technical, chemical, and biological characterization of biosolids from a sewage treatment plant and their use as a substrate component for producing seedlings of Anadenanthera macrocarpa. The study tested four substrate formulations with varying proportions of commercial substrate and biosolids, measuring seedling growth after fifty days.

Use Cases

• Modeling seedling growth response based on biosolid concentration in the substrate.
• Comparing substrate formulations for forestry nursery practices based on the described treatments.
• Assessing biosolid compliance with environmental regulations based on the chemical and biological analysis mentioned.

Strengths

• The study design included four distinct substrate treatments with four replications each.
• Seedling growth was measured using two specific characteristics: shoot height and stem diameter.
• Biosolid analysis was conducted according to a specific legal standard (CONAMA Resolution nº 375/2006).

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
