About Soil in Wallace County, Kansas

Alkaline Sands of the West

Wallace County features loamy sand from the Entisol order, reflecting its rugged, young soil profile. The average pH is 7.60, which is much higher than the national average of 6.5. This alkaline nature is typical for the drier, lime-rich environments of western Kansas.

Gritty Texture and High Porosity

With 29.1% sand and 47.9% silt, this soil is grittier than many other Kansas varieties. The 23.0% clay content provides just enough binding to help the soil maintain its shape. This texture allows for excellent aeration, making it easy for plant roots to breathe.

Consistent Water Storage Potential

Organic matter is lower than the state average at 1.79%, suggesting a need for compost or cover crops in home gardens. However, the available water capacity is exactly the state average of 0.180 in/in. This ensures that whatever rain does fall is stored effectively for plant use.

Efficient Drainage for Building

The soil is somewhat excessively drained and belongs to hydrologic group A. These characteristics mean water moves quickly through the ground, significantly reducing the risk of flooding or pooling. This makes the land excellent for construction and deep-rooted agriculture.

Tough Plants for Zone 6a

In hardiness zone 6a, focus on plants that can handle intense sun and alkaline sand. Succulents, native prairie grasses, and drought-hardy shrubs will thrive in this environment. Your garden can become a beautiful, low-maintenance oasis with the right native species.
