Duke Farm Soil Pit, 28 March 2019

Approximate coordinates: 36.008269, -79.020035

Description by Dan Richter: "Fantastic new Duke Forest soil excavation! Beautiful in so many ways -- in colors, in contrast of horizons, in its bedrock features inherited upto ~90cm, in its rhizogenic (root-formed) redox features, in its living grass rootlets down to 280 cm!, and in its impressive A and Bt horizons that overlie the upper saprolite!!"
