LESTER SERIES The Lester series consists of very deep,well drained soils that formed in calcareous loamy glacial till on till plains and moraines.These soils have moderate permeability.Their slopes range from 5 to 70 percent. Mean annual precipitation is about 28 inches.Mean annual temperature is about 47 degrees F. TAXONOMIC CLASS: Fine-loamy,mixed, superactive,mesic Mollie Hapludalfs TYPICAL PE ON: Lester loam with a convex slope of about 9 percent on a ground moraine in a cu ivated field. (Colors are for moist soil unless otherwise noted.) Ap--O to 7 inches; very dark grayish brown(10YR 3/2) loam, grayish brown(10YR 5/2) dry;moderate fine subangular blocky structure; friable; many fine roots; about 3 percent gravel; slightly acid; abrupt smooth boundary. (6 to 10 inches thick) Btl--7 to 21 inches; brown(10YR 4/3)clay loam; moderate medium subangular blocky structure; firm; any very fine roots; common very dark grayish brown(10YR 3/2)clay films on faces o peds and few very dark gray(10YR 3/1)organic coats on faces of peds; about 2 percent avel; slightly acid; clear smooth boundary. Bt2--21 to 38 in hes; dark yellowish brown(10YR 4/4)clay loam; moderate medium subangular bloc y structure; friable; common fine roots; common dark grayish brown (10YR 4/2)clay ilms on faces of peds and few very dark brown(10YR 2/2)organic coats on faces o peds; about 3 percent gravel; slightly acid; gradual smooth boundary.
