Our experienced writers spend hours deep researching, considering both scientific and experimental info to bring the insights you can trust.  

North Carolina’s agricultural industry is a vital part of the state’s economy.

North Carolina is a major producer of tobacco and sweet potatoes and is also a leading producer of poultry, hogs, corn, soybeans, and Christmas trees.

The state’s climate and geography are well-suited for agriculture, with warm summers and ample rainfall throughout much of the year.

The state’s soil is also rich in nutrients, making it ideal for crop growth.

Soil Order Of North Carolina

Soil / Sub OrderLocationCharacteristics
Ultisols/Udults and AquultsAquults are found in the coastal plain and Udults are found across the state.1. Aquults are the Ultisols in wet areas where groundwater is very close to the surface
2. Udults are the more or less freely drained, relatively humus-poor Ultisols that have a udic moisture regime.
Inceptisols/Udepts and AqueptsIn the Blue Ridge and the coastal plains1. Aquepts are wet Inceptisols. Their natural drainage is poor or very poor therefore, it needs to have artificially drained
2. Udepts are mainly freely drained Inceptisols that have a udic or perudic moisture regime.
Spodosols/AquodsIn the coastal plain1. These are the wet Spodosols.
2. They are characterized by a shallow fluctuating water table
Alfisols/UdalfsIn the piedmont region1. have a udic moisture regime
Entisols/Psammants and ArentsIn the piedmont region1. Psammants soils are sandy in all layers
2. Arents do not have diagnostic horizons because they have been deeply mixed by plowing, spading, or other methods of moving by humans
