In addition, Elkhart soils have thinner sola and have carbonates within a depth of 40 inches. Malcolm soils formed in noncalcareous interglacial silts and have thinner solum and more silt and clay in the lower part of the sola. Richwood and Toddville soils are on outwash plains and stream terraces, and have lower average and maximum clay content in the control section. Ripon soils have a lithic contact within a depth of 40 inches. Waupecan soils contain more coarse fragments in the lower part of the control section and have carbonates within a depth of 60 inches.
Lawndale soils have more mottles and low chroma colors throughout the control section.
Broadwell soils are on nearly level to rolling uplands near stream valleys. They formed in 40 to 60 inches of loess and in the underlying eolian loamy sand or sand. Slope gradients range from 0 to 12 percent. Mean annual temperature ranges from 50 to 54 degrees F, and mean annual precipitation ranges from 32 to 36 inches.
