About Soil in Lehigh County, Pennsylvania
Classic Pennsylvania silt-loam profile
Lehigh County soil features an average pH of 5.45, making it less acidic than the state average of 5.22. Despite this advantage, it remains below the national median of 6.5. The county's soil score of 46.4 is nearly identical to the overall Pennsylvania state average.
Balanced silt and sand distribution
The soil composition consists of 44.3% silt, 27.7% sand, and 15.5% clay. This creates a loam-like texture that is generally easy to work and provides a stable environment for root development. The clay content is sufficient to hold onto minerals without causing major drainage issues.
Reliable water capacity for urban gardens
The available water capacity is 0.142 in/in, which is very close to the state average of 0.151 in/in. Organic matter is 6.27%, exceeding the national average of 2.0% but falling behind the state's 12.14% benchmark. This indicates a soil that is reliable but benefits from seasonal mulching.
Versatile hydrology for the Lehigh Valley
Specific drainage classes are not listed, but the physical composition suggests moderate permeability. The balanced clay and silt ratio typically prevents the soil from becoming overly waterlogged or excessively dry. Local gardeners should monitor soil moisture during the high heat of July.
Abundant options in Zone 7a
A 7a hardiness zone allows Lehigh residents to enjoy a diverse range of ornamental and edible plants. From summer squash to perennial flowers, the climate and soil support a vibrant growing season. It's a great time to revitalize your outdoor space with local plantings.
