  1. Your first block-diagram (soil association) project

  2. From your syllabus: GEO 408 students will do research and write a report on two soil landscapes (aka soil associations), using NRCS Soil Survey data as their main source of information. Each project is an application of the skills learned in class, to a soil landscape. Each report will center on a major soil association, initially depicted in a county soil survey but much expanded upon in the report. YOU choose the soil association (which cannot be from Michigan), with my guidance and approval.

  3. From the Houghton County NRCS report

  4. Each project must contain at a minimum: 1. a block diagram of the soil association (using the one in the survey is acceptable; drafting a new one or editing an existing one is viewed as a plus). 2. typical profile descriptions and classifications for the major soils of the association, with an explanation of the reasons why the soils have the morphology that they do (why they are different from each other, etc). 3. soil and/or topographic maps (DEMs are OK) of typical landscapes in which this soil association dominates, appropriately annotated and explained. 4. an in-depth discussion of the soil parent materials and their pedogenesis, and how the pedogenic state factors have come together to form this association. See your syllabus for additional, optional components to your report

  7. Due date: Nov 8th at 5:00 pm This gives you two weeks to complete the project. • Other information: • Many paper surveys are in the soils lab. PLEASE RETURN them if you use one of these for your project. • You can also find block diagrams by using the NRCS block diagram web site. • I will look at and edit one draft of your project. Paper or digital – either is fine. • I will answer questions and try to help, in my office, at any time.
