About Soil in Kennebec County, Maine
Balanced Maine Acidity
Kennebec’s soil has a pH of 4.10, making it less acidic than the state average of 3.88 but still far below the national median of 6.5. This slight shift toward neutral can make nutrient uptake easier for some sensitive crops.
Gritty and Structured Soil
The soil mix contains 37.5% sand, 28.4% silt, and 7.8% clay. This balance creates a gritty, well-structured medium that resists the muckiness often found in heavier, clay-dominant soils.
Solid Organic Growth Potential
Organic matter stands at 28.72%, which is lower than the Maine average of 35.77% but still many times higher than the national average. The Available Water Capacity of 0.232 in/in is slightly below the state benchmark.
Well-Drained Bedrock Foundations
The soil is classified as well-drained with a dominant texture of bedrock. This means water moves through the profile quickly, reducing the risk of root rot but requiring more frequent watering in droughts.
Orchard Ready in Zone 5b
Falling in Hardiness Zone 5b, Kennebec is prime territory for diverse gardening. The well-drained soil is ideal for apple orchards and stone fruits that dislike wet feet during the spring thaw.
