This report provides a detailed analysis and interpretation of two distinct soil types in Lake and Orange Counties, Florida. Soil No. 1, located in Lake County, reveals significant horizon development with elevated iron accumulation and various subsoil characteristics, indicative of a subtropical climate and terrestrial influences. Meanwhile, Soil No. 2 from Seminole County demonstrates distinct floodplain properties with notable iron accumulation and a gradient of soil horizons. Both soils reflect unique environmental factors, offering insights into their classification and potential uses.
