Data Story
About Soil in Gray County, Texas
Alkaline profiles define the High Plains
Gray County soil averages a pH of 7.53, which is significantly higher than the 6.5 national median. While specific taxonomic data is limited, the high alkalinity influences which nutrients plants can absorb.
Gritty textures dominate the earth
Sand makes up 51.5% of the soil, paired with 24.5% silt and 19.6% clay. This gritty composition suggests a sandy loam that is easy to work but requires careful nutrient management.
High water capacity despite low organic matter
Organic matter measures 1.42%, trailing the 1.66% state average. However, the available water capacity of 0.135 in/in slightly exceeds the state average, providing a buffer during dry spells.
High runoff potential in group D
The soil falls into hydrologic group D, which indicates a higher potential for runoff and slower water infiltration. Gardeners should watch for surface pooling after heavy Panhandle storms.
Cooler climate gardening in zone 7a
Zone 7a supports hardy grains and cool-season vegetables like kale and carrots. Supplement the low organic matter with compost to give your home garden a boost.
