Technical Abstract: This is digital research data corresponding to a published manuscript, Loamy sand soil approaches organic carbon saturation after 37 years of conservation tillage. Conservation tillage is reported to increase soil organic carbon (SOC) and total nitrogen (TN) contents, but; long-term (> 30 years) field results quantifying the responses in Coastal Plain Ultisols are sparse. The distribution, accumulation, and topsoil storage of SOC and TN after 37 years of crop production using conventional (CvT) or conservation tillage (CnT) on a Norfolk loamy sand (fine-loamy, kaolinitic, thermic, Typic Kandiudult) were quantified. Soil samples were collected annually from the 0 to 5-, 5 to 10-, and 10 to 15- centimeter (cm) depth increments beneath corn (Zea mays), soybean (Glycine max), and cotton (Gossypium hirsutum) crops.
