The somewhat poorly drained Ayrshire soils are on interdunal areas. Runoff is slow on gentle slopes and medium on steeper slopes. Permeability is rapid or moderately rapid. Most areas are used for pasture or woodland. Some areas are used for corn, soybeans, small grain, forage crops, and specialty crops such as cantaloupe, watermelon and peaches.
Native vegetation is deciduous hardwoods, mainly oak and hickory.
Extent is moderate and mainly in MLRA's 114 and 115. Lawrence County, Illinois, 1952. The Bloomfield series was originally correlated in Greene County, Indiana in 1906. The series included soils now classified in the Princeton Series. The data in both Illinois and Indiana supports the change in classification from coarse-loamy to a sandy family.
