BEDROCKVery diverse geology
• Old volcanic intrusive and extrusive materials with diverse mineralogy
• Metamorphic
• Sedimentary
• 75% of soils in Puerto Rico developed from bedrock

Helping People Understand Soils
In the Caribbean Area, the U.S. began
conducting and publishing soil surveys in
the early 1900’s
In the US, soil surveys began in 1899
Parts of Utah, Maryland, and Connecticut
were first published soil surveys

Challenges in Conducting Soil Surveys in the Caribbean
Use same standards in the National Cooperative Soil Survey program
Big differences were accessibility, terrain conditions, and weather
Lack of access to lab data to classify the soils correctly and quickly
Around 20 different soil scientists worked in different decades to produce what we have today
