Data Story
About Soil in Jefferson County, Pennsylvania
Highly acidic woodland soil foundations
Jefferson County features an average pH of 5.03, significantly more acidic than the national median of 6.5. This measurement falls just below the Pennsylvania state average of 5.22, requiring lime for most traditional crops. Taxonomic data is currently limited for this region's soil profile.
A silty mix with low clay
The soil contains 37.6% silt and 20.6% sand, balanced by a relatively low 11.5% clay content. This composition typically offers moderate workability but may lack the structural stability found in heavier clay soils. These ratios suggest the land is prone to erosion if left uncovered.
Massive organic reserves but low water storage
Organic matter is exceptionally high at 30.85%, dwarfing the state average of 12.14%. However, the available water capacity sits at 0.105 in/in, which is lower than the state average of 0.151 in/in. This means while the soil is nutrient-rich, it struggles to hold onto moisture during dry spells.
Navigating uncertain drainage patterns
Specific drainage class and hydrologic group data are currently unavailable for Jefferson County. Local growers should perform site-specific percolation tests before starting major building or irrigation projects. Understanding your specific lot's runoff potential is crucial given the high silt content.
Resilient gardening in Zone 6a
With a USDA hardiness zone of 6a, this county is perfect for cool-weather crops like kale, garlic, and blueberries which thrive in acidic conditions. Use the high organic matter to your advantage by planting heavy feeders. Start your mountain garden today to make the most of this unique soil.
