2013 Region V Soil Judging - Practice Pits Day 1

Today we went to the Henderson property about 40 miles north of Springfield and just outside of Louisburg, MO. We were able to get in 5 practice pits in very diverse soils. While all of the soils were Alfisols, we saw gleyed horizons, buried A horizons and fragipans. Our team worked well in groups of 3, pairs, and when judging as a group - our understanding of local landscapes and local description conventions has significantly improved.

First Practice Pit of the competition - a Paleudalf in the rain (Erik Schilling, Wyatt Behrends, Heather Ryan and Andrew Krinke)
