LOCATION NARON KSEstablished Series
The Naron series consists of very deep, well drained soils that formed in loamy eolian sediments. These soils are on rolling small dunes on paleoterraces in river valleys of the Great Bend Sand Plains (MLRA 79). Slope ranges from 0 to 8 percent. Mean annual precipitation is about 700 mm (28 in.) and the mean annual temperature is about 14 degrees C (57 degrees F) at the type location.

Soil temperature regime: mesic
Mean annual soil temperature: 14 to 15 degrees C (57 to 59 degrees F)
