Amazon Basin Soil Nutrient Analysis for Anthrosol and Ferralsol

Nutrient availability and leaching data compare an archaeological Anthrosol and a Ferralsol from the Central Amazon basin. The study includes results from pot and lysimeter experiments with cowpea and rice, measuring biomass production and leaching of P, Ca, Mn, Zn, N, K, Cu, and Mg. Published in 2003 by Kluwer Academic Publishers, the report is associated with SCIOPS.

Use Cases

• Compare P, Ca, Mn, and Zn availability between Anthrosol and Ferralsol soil types to assess native fertility.
• Model N immobilization using soil C and N content data alongside C-to-N ratios.
• Analyze the impact of charcoal additions on plant uptake of P, K, Ca, Zn, and Cu from fertilizer treatments.
• Quantify nutrient leaching losses of N, Ca, and Mg under different soil and amendment conditions using lysimeter data.
• Correlate biomass production increases of 38-45% with soil type and fertilization status for cowpea and rice.

Strengths

• Direct comparison of two distinct Amazonian soil types (Anthrosol and Ferralsol).
• Reports specific biomass production increases of 38-45% for key crops.
• Measures multiple nutrient elements (P, Ca, Mn, Zn, N, K, Cu, Mg) for availability and leaching.

Limitations

• Dataset size (row count) and specific column structure are unknown.
• Data is from a single published study in 2003, limiting temporal recency.
• Geographic scope is limited to the Central Amazon basin.
