On 17-18 October 2016 backhoe drivers dug eight 2-m deep soil pits in three different research areas in the Calhoun CZO. The pits allow relatively easy access (though still difficult at times!) to soil and roots down to 2-m depth, a rare opportunity! Samples were split among five researchers who are working to analyze the samples for many different features. A large group of diverse researchers from six universities plus the USDA Forest Service participated in the intensive sampling that followed. Wofford College professors Kaye Savage and Terry Ferguson brought a large class of undergraduates by for a hands-on educational field trip. The soil profiles were formally described by grad student Caitlin Hodges of the University of Georgia as well as Lance Brewington, the MLRA Soil Survey Leader for the Piedmont Soil Survey Office of the USDA NCRS. Will Cook took detailed photographs of the pits, which are now available at the link below. The pits were open for 1 month to allow time for everyone to get all the samples they needed, then refilled on 21-22 November 2016. Four additional pits were installed on 21-22 November - news article on that linked below!
