About Soil in Maverick County, Texas
Alkaline Aridisols of the Border
Maverick County’s landscape is dominated by Aridisols with a high average pH of 8.05. This is much more alkaline than the national median of 6.5 and reflects the dry, desert-like conditions of the Rio Grande plain. These soils often contain high levels of calcium carbonate.
Loamy Texture with Desert Drainage
The soil is a balanced loam consisting of 36.2% sand, 36.4% silt, and 27.4% clay. This nearly equal split provides a good mix of drainage and moisture retention for native scrub and irrigated crops. The loamy texture makes the soil relatively easy to manage compared to heavy coastal clays.
High Water Capacity Despite Low Organic Matter
Organic matter is low at 1.37%, below the state average of 1.66%, which is typical for arid environments. However, the available water capacity is surprisingly high at 0.150 in/in, beating the state average of 0.133. This means that when it does rain, the soil is very efficient at holding that moisture for plants.
Well-Drained Land with Runoff Risks
The county’s soils are classified as well-drained but fall into hydrologic group D due to their tendency for high runoff during heavy storms. This classification suggests that while the soil profile can move water, the surface often resists rapid infiltration. Proper irrigation management is key to preventing surface erosion.
Warm Weather Wonders in Zone 9a
Residing in hardiness zone 9a, Maverick County supports citrus, olives, and heat-loving vegetables. The high pH means you should select plants that tolerate alkaline conditions or use sulfur to lower the pH in small garden beds. Start a drought-tolerant landscape to make the most of this sun-soaked climate.

Hydrologic Group
Group D — High Runoff
Clay soils with very slow infiltration rates. Highest runoff potential. These soils have a permanent high water table or are shallow over impervious material.
Drainage Class
Well drained
Water is removed from the soil readily but not rapidly. Optimal for most plants and construction.

Frequently Asked Questions
What type of soil does Maverick County have?
Maverick County's soil is classified as Loam. This indicates the relative proportions of sand, silt, and clay — 36% sand, 36% silt, and 27% clay. Loamy soils hold moisture well and support a wide range of plants.
Is Maverick County's soil acidic or alkaline?
Maverick County's soil has a pH of 8.1, which is mildly to moderately alkaline. Sulfur amendments can lower pH if needed.
What is the drainage class for Maverick County?
Maverick County has a dominant drainage class of "Well drained." Well-drained soils allow excess water to move through quickly, reducing waterlogging risk and supporting most field and garden crops.
What crops or plants grow well in Maverick County's soil?
Based on Maverick County's Loam texture, pH of 8.1, and Well drained, the soil is well suited for drought-tolerant crops and native grasses, row crops and vegetable gardens, most annual and perennial crops.
What USDA soil order is found in Maverick County?
Maverick County's dominant soil order is Aridisols. Aridisols are soils of dry environments with low organic matter. They often have salt or calcium carbonate accumulations at depth.
