NEHSTC “Field Indicators” – most of the spodic indicators developed for frigid soils – redox in E, etc. Spodosols not really mapped in mesic area (even though they exist).

Nov 1, 2014 · Field Indicators of Hydric Soils in the United States is a guide to help identify and delineate hydric soils in the field (fig. 1). Indicators are not intended to replace or modify the requirements contained in the definition of a hydric soil. The list of indicators is considered to be dynamic; changes and additions are likely to be made annually.

TA6. Mesic Spodic For testing in MLRAs 144A and 145 of LRR R and MLRA 149B of LRR S.

This indicator is used to identify wet soils that have spodic materials or that meet the definition of Spodosols. The layer described above that has value of 4 or more and chroma of 2 or less is typically described as an E or Eg horizon.

TA6. Mesic Spodic. (ONLY MLRA 144A, 145, & 149B). A layer ≥5cm(2in) thick starting within 15cm(6in) of the mineral soil surface that has value ≤3 & chroma ≤2 that is underlain by either: a...

Mesic Spodic Developed • Reviewed over 30 pedon descriptions, OSED’s, soil survey, etc. • Data entered to spread sheet with colors, depths, horizons, redox.

User Notes: This indicator is used to identify wet soils that have spodic materials or that meet the definition of Spodosols. The layer or layers described above that have value of 4 or more and chroma of 2 or less are typically described as E or Eg horizons.

Apr 17, 2017 · Add “A17.—Mesic Spodic. For use in MLRA 144A and 145 of LRR R and in MLRA 149B of LRR S. A layer that is ≥5 cm (2 inches) thick, that starts at a depth ≤15 cm (6 inches) from the mineral soil surface, that has value of 3 or less and chroma of 2 or less, and that is directly underlain by either:

a partially or wholly cemented spodic horizon usually within 18 inches of the surface measured from the bottom of the 0-horizon; and mottling within the spodic horizon.
