CCZO -- Soil Biogeochemistry -- Calhoun CZO -- (2015-2016)

Topic: The depth and persistence of land use effects on soil biogeochemistry at the Calhoun CZO

This file contains data of biogeochemical parameters of soils collected at the Calhoun CZO during 2015 and 2016 and analyzed at the University of Kansas. Please visit the “Read me” worksheet for a detailed explanation of the methods used to obtain the data.

Data in the worksheet “fixed depth sampling” originate from three Hardwood forest, three Pine forest and two cultivated sites. At each of these eight sites, we hand-augered and collected soil samples, integrating samples collected at depths between 40 and 50 cm, 100 and 150 cm, 150 and 200 cm, 250 and 300 cm, and 400 and 500 cm.

Data in the worksheet “Big Dig 2016” also originate from Hardwood forest, Pine forest and cultivated sites, ten sites in total. Instead of collecting soils from fixed depths, we sampled according to diagenetic soil horizons, as determined in joint group efforts during the “Big Dig” field trip in October 2016.

主题：在卡洛顿综合研究区（CZO）土壤生物地球化学中，土地利用效应的深度与持久性
本文件收录了2015年和2016年在卡洛顿综合研究区采集并经堪萨斯大学分析的土壤生物地球化学参数数据。请参阅“读取说明”工作表，以获取获取数据的详细方法解释。
“固定深度采样”工作表中的数据来源于三个硬木森林、三个松树林和两个耕作地。在每个这八个地点，我们手工挖掘并采集了土壤样品，整合了40至50厘米、100至150厘米、150至200厘米、250至300厘米和400至500厘米深度的样品。
“2016年大挖掘”工作表中的数据同样来源于硬木森林、松树林和耕作地，共计十个地点。与从固定深度采集土壤不同，我们根据2016年10月“大挖掘”野外考察期间联合小组确定的成土层位进行采样。
