The Baltic series consists of very deep, poorly drained and very poorly drained soils formed in clayey alluvial sediments in depressions and on bottom lands.
Permeability is slow.
Slopes range from 0 to 2 percent. Baltic silty clay loam - on a slope of less than 1 percent in a large, cultivated, upland depression. When described, the soil was moist throughout. Thickness of the mollic epipedon ranges from 24 to 60 inches. This soil contains free carbonates throughout and is slightly alkaline or moderately alkaline.
