Practice exam #3 - QUESTION 6

Fragment of a discussion from Course talk:APBI200

a)Gleysolic order, Bg diagnostic horizon

b)Well, the Goose soil has very low sodium content throughout its layers. The presence of a semi-thick Ah layer would be good for some plants, but this environment seems like it would largely make growth difficult for plants. To start, we have multiplegleyed horizons, implying spells of intense anaerobic conditions. Nd All layers below the Ah have a high percentage of clay and therefore micro pores. The small pore size and massive structure will make water extremely difficult for plant roots to access, as is borne out in our data for Goose.

That's all for me! Look forward to corrections and other peoples' responses :)
