Soils

Wymore soils are on slopes and ridgetops that are good for growing wheat and grain sorghum. Soil erosion can be a problem if crop residues are not left on the soil surface. It has good water holding capacity.

The two top layers are called Ap1 and Ap2 (you can see the two red spikes that separate the different soil horizons or layers) because they are plowed layers. These two Ap horizons are about 10 inches deep and have a granular structure. Most of the wheat roots will be in these two layers. But some roots will grow into the third layer, which is a subsoil layer, called the Bt horizon. This layer contains more clay than the upper horizons and has a prism-like structure. As you move down into the next layers, the clay content continues to increase and you can see the soil color is becoming redder. Lime is present in the lower horizons because of weathering and leaching from the upper horizons. This is a pretty neat hole, huh?

This hole and picture were provided by Dr. Mickey Ransom,  Department of Agronomy, K-State.
