We are excited to be back here on the soil judging blog – and to share the team’s experiences from this year’s regional contest at the end of September, hosted by Kansas State University in Great Bend, Kansas.
This year’s team of 8 students earned second place in team judging and third place overall to qualify for this spring’s National Contest in Stevens Point, Wisconsin! We had a judger place in the top ten. Go Gophers! We will be joined by fellow Region V teams Kansas State University (1st place) and Iowa State University (2nd place) in April in Wisconsin.
This year’s regionals team. L to R: Ava McCune (co-captain), Brynn Miller, Annika Selstad, Tara Bluni, Anna Windels, Amital Shaver (co-captain), Finn Porter, Nic Jelinski (coach), Jenna Christenson.
Located at a bend in the Arkansas River (which we learned from locals is pronounced ar-KAN-sas, like the state we were in), Great Bend sits between a large sand sheet and the Cheyenne Bottoms, a 64-square-mile wetland complex and an important stopover site for migratory birds. From dunes to floodplains, the team was able to dig into some diverse soils. In this year’s contest, the judgers were asked to assess pits for Hydric Soil Indicators. Our eyes were peeled for redoximorphic features!
A hydric soil in an interdune. Classification was tricky and debated with these! Check out those concentrations in the fourth horizon.
The dunes, covered in prickly vegetation, were often the land of Ustipsamments, and the team worked on honing clay percentages in sandy soils.

Lamellae!

We headed out to the Cheyenne Bottoms and got our hands on some much darker and clayier soils. The Gophers were excited to see some natric horizons, as well as beautiful gypsum rosettes. The presence of salts led to some alphabet soup horizons – Btsskyzg, for example.

Very different structure than in dunal soils.
The team loved group judging of complex pits, engaging in discussion and sharing interpretations. We loved getting into the nitty gritty during daily team meetings, learning more and more about area geology, and becoming one with our texture triangles.

We extend a huge thank-you for the generosity of donors, without which the incredible and formative experiences of soil judging would not be possible. The opportunity to travel, see soils nationwide, and connect with fellow students passionate about soil scientists helps cultivate the next generation of bridge-builders and soil, agricultural, and environmental science professionals. Thank you so much.
