Soil Profiles of Amazonia

Summary:

Soil Profiles of Amazonia contains soil profile descriptions for 1153 locations throughout Brazil. These data are primarily based on RADAMBRASIL surveys.

1. Data Set Overview

Data Set Identification:
Soil Profiles of Amazonia
Data Set Introduction:
This dataset consists of 30 spreadsheet files listing soil profile descriptions for 1153 locations across Amazonia.
Objective/Purpose:
These data were collected and prepared in the current format as input to a rooting depth model which was used to produce a Amazon regional map of plant available water (Negreiros & Nepstad, 1994).
Summary of Parameters:

Soil Profiles

The data provided in these profiles were manually entered into spreadsheet form from a number of published volumes, maps, and articles (see REFERENCES).

Soil Profiles of the Brazilian Amazon contains 1153 soil profiles at varying locations (see DATA DESCRIPTION: Data Characteristics: Variable Description/Definition, for a complete listing).
