About Soil in Sherman County, Kansas
Alkaline Mollisols of the Western Edge
Sherman County is defined by Mollisols with an average pH of 7.54, making it more alkaline than the 6.80 state average. These soils are characteristic of the grassland ecosystems that once covered the High Plains. The soil score of 50.6 indicates moderate productivity for the region.
Clay Loam with High Silt Content
The dominant clay loam texture is built from 58.2% silt, 22.1% clay, and 19.7% sand. This high silt ratio gives the soil a floury feel and contributes to its ability to hold onto nutrients. However, the clay content can make it heavy when wet.
Exceptional Water Retention for Semi-Arid Land
Available water capacity is 0.198 in/in, which is higher than the state average of 0.180 in/in. This ability to store moisture is crucial because organic matter is slightly low at 2.02%. The soil acts as a sponge, holding onto rare rainfall to support crop growth.
Poorly Drained Soils in Group C/D
Classified as poorly drained and falling into hydrologic group C/D, these soils can struggle with slow water infiltration. This can lead to ponding during heavy storms or slow drying times in the spring. Homeowners should consider raised beds to avoid root rot in these heavy conditions.
Navigating Hardiness Zone 6a Conditions
The 6a hardiness zone favors hardy grains and cool-season grasses that can withstand temperature swings. For home gardens, adding organic mulch can help manage the high pH and slow drainage. It is a rewarding environment for those who understand the local water dynamics.

Hydrologic Group
Group C — Moderate-High Runoff
Soils with slow infiltration rates, often with a layer that impedes downward water movement. Higher clay content restricts drainage.
Drainage Class
Poorly drained
Water is removed so slowly that the soil is wet at or near the surface much of the year. Drainage improvement usually needed.
