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

OVERVIEW

Description/Abstract

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.
