About Soil in Navarro County, Texas
Rich Vertisols of the Blackland Prairie
Navarro's soils are primarily Vertisols, known for their high clay content and shrinking-swelling nature. The pH of 7.01 is near neutral and sits very close to the state average of 7.09.
Heavy clay defines the land
With 29.8% clay and 43.2% sand, the soil is physically heavy and holds its shape. This texture provides excellent support for plant roots but can be difficult to work when too wet or dry.
Superior organic matter and water storage
At 1.74%, organic matter exceeds the Texas state average of 1.66%. The soil's water capacity of 0.143 in/in also beats the state benchmark, making it very productive for farming.
Slow drainage requires careful planning
The soil is moderately well-drained but falls into hydrologic group D. Water moves slowly through the clay layers, which can lead to standing water after intense rainfall.
Cotton and corn excel in 8b
Zone 8b combined with fertile Vertisols makes this a powerhouse for cotton, corn, and sunflowers. Get your garden started and take advantage of this naturally rich soil.
