HISTOSOLS: Their Characteristics, Classification, and Use

WebCryumbrepts, and Cryorthods. The Inmachuk and Lemeta soils are deep Fibrists. The Susitna and Takotna soils are well drained stratified sandy and silty soils of floodplains. Drainage and Permeability: Poorly drained. Internal drainage is blocked by permafrost. WebThese soils contain few weatherable minerals and are often rich in Fe and Al oxide minerals. Most of these soils are characterized by extremely low native fertility, resulting from very low nutrient reserves, high phosphorus retention by oxide minerals and low cation exchange capacity (CEC).
