Reaction ranges from extremely acid to moderately acid in the subsurface tier and very strongly acid to slightly acid in the bottom tier in 0.01M calcium chloride. These are the Lupton , Pywell , Seelyeville , and Tendoy series in the same family. These series all have lower annual precipitation than the Bucksport series. In addition, Lupton soils typically have higher soil reaction in the control section. Pywell soils have thin layers of volcanic ash.
Seelyeville soils have less woody fibers and or fragments.
Tendoy soils have calcium carbonate in the upper part of the surface tier. Bucksport soils are in bogs, primarily in depressions in ground moraines, glaciofluvial deposits, and between shallow till ridges. They range from small enclosed bogs to areas of several hundred acres. Slope is 0 to 1 percent. Bucksport soils formed in organic material from 51 inches to over 12 feet thick.
