Data Story

About Soil in Nevada County, Arkansas

Heavy Vertisols dominate the landscape

Nevada County is defined by its Vertisols, a taxonomic order known for high clay content and dramatic shrinking and swelling. The average pH of 5.34 is significantly more acidic than the national median of 6.5. These characteristics contribute to a soil health score of 27.7, placing it below the Arkansas state average of 37.7.

Silty clay loam requires patience

The dominant texture is silty clay loam, comprised of 52.2% sand and 15.0% clay. This specific mix can become extremely hard when dry and sticky when wet, making the timing of cultivation critical for success. Despite the high sand percentage, the silty clay components dictate the overall workability and drainage patterns.

Modest organic matter and water storage

At 1.75%, the organic matter content is below both the national average of 2.0% and the state average of 4.15%. However, the available water capacity of 0.144 in/in nearly meets the state average of 0.148, offering decent drought resistance. To boost productivity, local farmers often incorporate cover crops to build up the thin organic layer.

Navigating somewhat poor drainage

The landscape is classified as somewhat poorly drained and belongs to Hydrologic Group D. This combination means that water often sits near the surface after rain, which can drown sensitive root systems. Raised beds are a highly effective solution for gardeners looking to bypass these drainage limitations.

Gardeners thrive in Zone 8a

Nevada County sits in Zone 8a, where the long summers are perfect for tomatoes, peppers, and melons. The acidic Vertisols are well-suited for timber production and specialized gardening of camellias and blackberries. Starting a garden here is rewarding if you focus on improving soil structure with consistent composting.

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

Somewhat poorly drained

Water is removed slowly enough that the soil is wet at shallow depths for significant periods. Mottling present.

Is Nevada County's soil acidic or alkaline?

Nevada County's soil has a low pH of 5.3, which is strongly acidic. Acidic soils benefit from lime applications to raise pH and improve nutrient availability.

What is the drainage class for Nevada County?

Nevada County has a dominant drainage class of "Somewhat poorly drained." Poorly drained soils retain water for extended periods, which can limit crop choices and may require tile drainage or raised beds.

What crops or plants grow well in Nevada County's soil?

Based on Nevada County's Silty clay loam texture, pH of 5.3, and Somewhat poorly drained, the soil is well suited for acid-loving plants like blueberries and azaleas, row crops and vegetable gardens, rice, cranberries, and other water-tolerant species.

What USDA soil order is found in Nevada County?

Nevada County's dominant soil order is Vertisols. Vertisols are clay-rich soils that shrink and crack when dry and swell when wet. They are challenging to manage but often fertile.
