Data Story
About Soil in Jackson County, Texas
Neutral soils of the Gulf Coast
Jackson County has a soil pH of 6.64, which is nearly identical to the national median of 6.5. This is more acidic than the state average of 7.09, reflecting its position near the humid Gulf Coast. These neutral soils are highly sought after because they allow for maximum nutrient availability for most crops.
Sandy textures on the coastal plain
The soil is primarily sand at 52.5%, with 25.5% clay and 22.0% silt. This high sand content promotes rapid drainage in the upper soil profile and makes the earth easy to till. However, the significant clay fraction provides enough body to keep the soil from becoming overly loose or dry.
Rich organic matter for coastal farming
Organic matter is impressive at 2.10%, surpassing both the Texas average of 1.66% and the national average of 2.0%. While the available water capacity is slightly below state average at 0.124 in/in, the overall soil score is a high 44.5. This indicates very high potential for agricultural productivity and gardening success.
Managing high runoff potential
Jackson County falls into hydrologic group D, which means the soil has very low infiltration rates when saturated. In this coastal environment, heavy rainfall can lead to significant runoff and standing water. Drainage planning is a key consideration for both residential landscaping and large-scale agriculture.
Tropical vibes in Zone 9a
Located in USDA Hardiness Zone 9a, Jackson County is ideal for citrus, figs, and long-season vegetables. The high organic matter and neutral pH provide an incredible head start for any garden enthusiast. Start your own coastal oasis and enjoy the benefits of some of the state's best soil.
