Data Story

About Soil in Pope County, Arkansas

Highly weathered Ultisols define the land

Pope County is dominated by Ultisols, which are highly weathered forest soils characterized by an acidic pH of 5.53. This measurement sits well below the national median of 6.5 but aligns closely with the Arkansas state average. These soils typically require lime applications to neutralize acidity for most vegetable crops.

Classic fine sandy loam texture

The soil composition is 44.6% sand and 39.7% silt, resulting in a dominant texture of fine sandy loam. This mix offers excellent workability for farmers and gardeners alike. The 15.7% clay content provides just enough structure to assist with nutrient retention without becoming overly heavy.

Moderate water capacity with low organic levels

Organic matter stands at 1.84%, which is lower than both the national 2.0% average and the state average of 4.15%. However, the available water capacity of 0.140 in/in is nearly on par with the state average of 0.148. Improving organic content through composting will significantly boost both fertility and moisture retention.

Reliable moderately well-drained soils

Pope County soils are generally moderately well-drained and fall into hydrologic group C. This means the soil has a slow rate of water transmission, which can lead to occasional pooling after heavy rain. It is a solid middle-ground for building foundations and most agricultural uses.

Warm winters favor zone 8a crops

The 8a hardiness zone supports a long growing season for heat-tolerant crops like peppers, tomatoes, and okra. With a soil score of 31.9, success depends on managing the acidic Ultisol profile through consistent soil care. Now is the perfect time to prep your garden beds for a bountiful Arkansas summer.
