Wetlands soils are sometimes refered as mucky. The soils found in wetlands are different then the soils found in dry lands. They are called hyrdric soils because the spaces between each grain of soil is filled with water. The color of these soils is usually dark brown to black due to the presense of mineral or organic matter. Wetland soils may also have a rotten egg smell due to the presense of sulfur, hence being mucky!
