Data Story

About Soil in Matagorda County, Texas

Balanced Soils on the Gulf Coast

Matagorda County boasts a near-neutral average pH of 6.80, closely aligning with the national median of 6.5. This balanced pH makes the soil extremely versatile for a wide range of agricultural activities. It is significantly more balanced than the more alkaline soils found further inland.

Heavier Textures for Nutrient Storage

The soil is a heavy mix of 31.6% clay and 31.4% silt, with 37.0% sand rounding out the profile. This high clay and silt content provides excellent nutrient retention and creates a fertile base for intensive farming. However, these heavier soils can become difficult to work when they are overly wet.

Rich Organic Matter and High Potential

The organic matter content is an impressive 2.71%, far exceeding the Texas state average of 1.66%. The available water capacity is 0.131 in/in, which is nearly identical to the state average. This combination makes Matagorda one of the more naturally fertile counties in the state.

Managing Water in Group D Soils

Classified as hydrologic group D, these soils have a very slow infiltration rate and high runoff potential. This is common in low-lying coastal areas where heavy clays and a high water table dominate the landscape. Farmers often use drainage ditches and raised rows to prevent waterlogging.

Bountiful Gardens in Zone 9b

With a tropical-leaning hardiness zone of 9b, Matagorda County is ideal for citrus, rice, and year-round vegetable gardening. The high organic matter supports vigorous growth for almost anything you plant. Try your hand at growing lemons or lush tropical ornamentals in this coastal haven.
