Section 62-340.450, F.A.C. Hydric Soils and Hydric Soil Indicators Flashcards
Hydric Soil
a soil that is saturated, flooded, or ponded long enough during the growing season to develop anaerobic conditions in the upper part of the soil profile that favor the growth and regeneration of hydrophytic vegetation
Inundated Soil
when the water table is at or above the soil surface
Flooded Soil
a soil is flooded if the water is moving across the soil surface as in a slough or on a floodplain
Ponded Soil
a soil is ponded if the water is sitting on top of the soil with no movement to an outlet, as is the case with some depressions
Saturated Soil
when the water table is within 6” of the soil surface for sandy textured soils or within 12” for loamy or clayey textured soils
USDA - NRCS Recognized Hydric Soil Indicators
four indicators that are evidence of a water table at or above the soil surface for more than several weeks during the growing season: 1) muck, 2) mucky texture, 3) grey colors, and 4) sulfidic odor
Hydric Soil Indicators of Saturation
1) dark surface, 2) organic accretions, 3) oxidized rhizospheres, 4) polychromatic matrix (matrix stripping), stratified layers, 6) iron and manganese concretions (loamy and clayey ONLY), 7) distinct or prominent mottles (loamy and clayey ONLY), and 8) marl (loamy and clayey ONLY)
