Soil Colors And Fertility In Eastern Regions
The article explains how surface soil color signals fertility, with dark brown to black surfaces indicating organic matter and higher fertility in humid eastern areas. Red and brick colors in the Piedmont and coastal plains suggest well drained, long weathered soils with good moisture retention, while pale gray subsoils indicate poor internal drainage. It cautions that not all dark soils are fertile and that subsoil color reveals drainage conditions, urging careful interpretation by farmers and scientists.
