Field notes
The page describes the source as the USDA NRCS soil survey (SSURGO) and lists county counts by state. Visitors can choose among options ranging from lawn and vegetables to blueberries and blue or pink hydrangeas; a shaded band on the pH scale indicates a plant’s preferred range. The page cautions that local conditions can differ substantially and recommends sending a soil sample to a state extension lab before applying amendments.
