Soils consisting primarily of peat are known as histosols. Peat forms in wetland conditions, where flooding or stagnant water obstructs the flow of oxygen from the atmosphere, slowing the rate of decomposition. [4] Peat properties such as organic matter content and saturated hydraulic conductivity can exhibit high spatial heterogeneity. [5]
Muck soils are defined by the USDA NRCS as sapric organic soils that are saturated more than 30 cumulative days in normal years or are artificially drained. [6] An example would be a soil made up primarily of humus from drained swampland. [citation needed]
