Lab assignment 6

For Lab assignment 6 Question 2, it asks to identify the soil horizon. I thought soil horizon was referring to O, A, B, or C horizon, so I put those as my answers. But, it seems like the question was asking for different organic horizons (L,F,H). For these types of questions, how are we supposed to know whether to put soil horizons or types of organic horizons?

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
