Site Description
Konza Prairie Agroecosystem (KONA) is a terrestrial NEON field site is located in the Flint Hills region of Kansas just 10 km (6 mi.) south of Manhattan, KS. Sampling occurs in a 3.6 km2 (903 acre) area of cultivated crop fields owned and managed by Kansas State University’s Department of Agronomy and Department of Animal Science and Industry. The site is focused on sampling within agricultural systems. The surrounding region consists of grasslands, forests, and agricultural land cover types and includes the largest remaining areas of unplowed tallgrass prairie in North America. KONA is part of the NEON Prairie Peninsula Domain (D06), which stretches from Kansas through Nebraska and Iowa to southern Minnesota, and moves east to encompass Illinois and most of Indiana. The Domain hosts four other NEON field sites: two aquatic and two additional terrestrial, all of which are located in Kansas. KONA is colocated with the KING aquatic field site and just 5 km (~3 miles) west of the KONZ terrestrial site. The two sites provide a contrast between more pristine prairie at KONZ and heavily impacted agricultural land at KONA within the same area. Land use and land use management are key grand challenge themes for this Domain.

Geology
The agricultural fields at KONA are composed of alluvium, a type of sediment deposited by flowing water made of gravel, sand, silt, clay, or other rock particulates. The fields lie above the Chase group, which is a geologic group from the early Permian laid down in the Gearyan stage. The group is composed of cherty limestone and green or red shale. Chert is another term for flint, meaning a sedimentary rock composed of quartz. It this “flinty” limestone that gives the Flint Hills, home of the Konza Prairie, its name.
Vegetation
All sampling plots in KONA are located in cultivated crop fields. Crops vary year to year but the most commonly planted are wheat, corn, milo, soybeans, alfalfa, and oats.
Soils
The dominant soil series is Chase silty clay loam, rarely flooded. The soil remains silty clay loam to a depth of 0.33 m (1 ft.), where it changes to silty clay. It is somewhat poorly drained and has a moderately low to moderately high water capacity.
