About Soil in Franklin County, Kansas
Naturally Acidic Soils in Eastern Kansas
Franklin County has a notably acidic average pH of 5.93, falling well below the national median of 6.5. This low pH is typical for the more humid eastern regions of the state and may require lime applications for certain crops. The overall soil score of 56.5 is slightly above the Kansas state average.
Fine-Silted Clay for Strong Retention
The soil is comprised of 54.8% silt and 25.0% clay, with very little sand at only 15.7%. This fine texture creates a heavy soil that excels at holding onto nutrients but can be difficult to work when wet. Gardeners should wait for the soil to dry before tilling to avoid clodding.
Rich Organic Matter and Solid Capacity
Organic matter is quite high at 2.57%, easily beating the state average of 2.22%. The available water capacity of 0.182 in/in is also slightly above the state average of 0.180. These metrics suggest a fertile land capable of sustaining lush growth throughout the season.
Managing Heavier Water Movement
Because of the low sand content and high silt, water moves through these soils relatively slowly. While specific drainage class data is unavailable, this composition often leads to ponding during heavy spring rains. Proper drainage management is key for both agricultural yields and residential basement stability.
Ideal for Soybeans and Corn in Zone 6b
Zone 6b in Franklin County is perfect for traditional Kansas row crops like corn and soybeans. The acidic nature of the soil also makes it a great spot for blueberries and azaleas, which struggle elsewhere in the state. Dig in today and take advantage of some of the richest organic matter in Kansas.
