Data Story
About Soil in Sherman County, Texas
Alkaline Landscapes in the High Plains
Sherman County features a noticeably alkaline profile with an average pH of 7.65, significantly higher than the national median of 6.5. This high pH level influences how plants absorb nutrients across the region's vast agricultural acreage. While the specific taxonomic order remains unclassified in recent surveys, the chemical signature remains consistently basic.
A Gritty Mix with High Sand Content
The soil contains 47.3% sand and 26.9% silt, creating a texture that balances aeration with structure. A clay component of 21.6% provides enough binding to prevent the soil from becoming purely granular. This composition allows for decent workability but requires careful management to prevent erosion.
Efficient Water Storage Despite Low Carbon
Organic matter sits at 1.28%, trailing both the Texas state average of 1.66% and the national average of 2.0%. However, the soil excels in water retention with an available water capacity of 0.154 in/in, which beats the state average of 0.133 in/in. This efficiency helps crops survive the dry spells common to the Panhandle.
Navigating High Runoff Potential
The county belongs to Hydrologic Group D, indicating a very low infiltration rate and high runoff potential when wet. While specific drainage class data is unavailable, this group often presents challenges for heavy construction and large-scale irrigation. Producers must manage water carefully to avoid surface pooling and topsoil loss.
Tough Crops for Zone 7a
In USDA Hardiness Zone 7a, growers find success with winter wheat and hardy sorghum that can withstand the alkaline conditions. The high water capacity supports deep-rooted native grasses and resilient garden staples like peppers and tomatoes. Start your garden with soil amendments to balance the pH and boost productivity.
