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 PEDON: Lester loam with a convex slope of about 9 percent on a ground moraine in a cultivated field. (Colors are for moist soil unless otherwise noted.) Ap--0 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; many very fine roots; common very dark grayish brown(10YR 3/2) clay films on faces of peds and few very dark gray(10YR 3/1) organic coats on faces of peds; about 2 percent gravel; slightly acid; clear smooth boundary. Bt2--21 to 38 inches; dark yellowish brown (10YR 4/4) clay loam; moderate medium subangular blocky structure; friable; common fine roots; common dark grayish brown (10YR 4/2) clay films on faces of peds and few very dark brown (10YR 2/2) organic coats on faces of peds; about 3 percent gravel; slightly acid; gradual smooth boundary. (Combined Bt horizon is 10 to 40 inches.) Bkl--38 to 50 inches; yellowish brown(10YR 5/4) loam; weak medium subangular blocky structure; friable; few fine roots; common very pale brown (10YR 8/2) carbonate threads; about 2 percent gravel; violently effervescent; slightly alkaline; clear wavy boundary. Bk2--50 to 60 inches; yellowish brown(10YR 5/4) loam; weak medium subangular blocky structure; friable; common fine distinct yellowish brown (10YR 5/6)relict Fe concentrations; common very pale brown(10YR 8/2) carbonate threads; about 2 percent gravel; violently effervescent; slightly alkaline; clear wavy boundary. C--60 to 80 inches; yellowish brown (10YR 5/4) loam; ; massive; friable; common medium distinct yellowish brown (10YR 5/6)relict Fe concentrations and few fine distinct light brownish gray(10YR 6/2)relict Fe depletions; about 1 percent gravel; strongly effervescent; slightly alkaline.
