A mineral-soil diagnostic horizon, formed from an accumulation of clay, silt, and humus, which has moved down from an overlying, cultivated soil layer. It is a soil horizon created by agricultural management, and is identified by its near-surface position, and by colloids accumulated in the pores of the soil. The name is from the Latin ager, meaning field.
