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.

Runoff potential:High

Drainage Class

Well drained

Water is removed from the soil readily but not rapidly. Optimal for most plants and construction.

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.
