A typical Bayamon soil profile consists of a 20 cm topsoil of dark reddish brown clay and a weak red clay subsoil to a depth of 2 meters, or more. The Bayamon soils formed in highly weathered, clayey marine sediments. Thee soils have low to medium fertility and are strongly acid to extremely acid throughout the profile.
Crops respond well to applications of lime and fertilizer.
Bayamon is also the name of one of the main cities and a river.
