Lab assignment 6

You should be able to identify both mineral and organic horizons (particularly important are diagnostic horizons for the 10 soil orders)

re: horizon designations: for mineral horizons - only the C horizon can be on its own; A and B horizons will always be accompanied by a lower case letter

for organic horizons - 1) know how to identify an organic horizon - hint it is related to the %C 2) be clear on the distinction between poorly drained and well drained organic horizons

O will always have a lower case letter with it - Of, Om or Oh LFH are sometime written together In the case of lab #6 (Forest Floor), question #2 - parts b) and c) are distinguishing between H and Ah; part d) is asking you to identify the type of F horizon - Fa, Fm or Fz
