Sols Bruns Acides of the Northeastern United States¹

ABSTRACT

Sols Bruns Acides is the name now used in Belgium, France, and possibly other European countries for a class of soils at the great soil group level. Similar soils have developed under forest vegetation in the Northeastern United States, and it is proposed that the same name be applied here. In the past these soils have been included with Brown Podzolic, weak Podzol, weak Gray-Brown Podzolic or Red-Yellow Podzolic soil groups. Morphologically, Sols Bruns Acides have a thin A₁ horizon; a paler A₂ or A₂-like horizon (possibly a B₁ horizon) which is poorly differentiated from the B₂ horizon; a B₂ horizon with uniform color from top to bottom, weak subangular blocky structure, and silicate clay accumulation not evident or appearing only in traces. Sola of these soils are strongly to very strongly acid and have low base status. Distinction between Sols Bruns Acides and the Gray-Brown Podzolic and Red-Yellow Podzolic soils rests mainly on amounts of clay accumulation in the B horizon. Sols Bruns Acides differ from weak Podzols and Brown Podzolic soils mainly in color and structure of the B horizon. The latter have in the upper B horizon strong colors which fade with depth and weak, fine granular structure.
