Soil percent carbon and nitrogen from 9 hillslopes sites in Macon County, North Carolina, within the Upper Little Tennessee River Basin

Percent carbon and percent nitrogen of soil were analyzed as part of the hillslope plots in Macon County, North Carolina. There were 9 hillslope sites representing a gradient of development, including forested, valley agriculture, and mountain housing developments. There were 12 10 x 10-m plots at each site. A soil probe was used to collect soils from 3 depths at each plot: 0-10 cm, 10-30 cm, and 30 + cm. Soil was then dried, processed, and analyzed for percent C & N at the Coweeta Analytical Laboratory.作为北卡罗来纳州梅肯县山坡样地研究的一部分，研究人员对土壤的碳百分比与氮百分比进行了分析测定。本次研究共设置9处山坡采样点，覆盖了林地、河谷农业、山地住宅开发等不同开发梯度。每个采样点均布设12个10米×10米的样地。使用土壤探针在每个样地的三个深度层采集土壤样品：0-10 cm、10-30 cm以及30 cm以上。随后将土壤样品进行干燥与前处理，并送至科威塔分析实验室（Coweeta Analytical Laboratory）完成碳、氮百分比含量的检测分析。
