1. Turn in INDIVIDUAL reports: • Keep your report to 2 pages of text. Show all your calculations (a separate page to show calculations is ok) • 1. Give 4 examples of how specific soils information (such as a specific soil property (e.g. texture, horizon etc.) could be used to tell you about the productivity or use of a site. Include an example of how you would use this information. • What are 2 examples of microclimate information that could be useful when considering land management choices? Explain each. • Soil samples were collected in the field and total N concentrations are given in Friday’s lecture. Using these data, calculate the TOTAL amount of N (in kg ha-1) present in each soil profile at the two sites you visited in the field. Be sure to sum the N from ALL horizons at each site. SHOW your calculations and tell us what this total N value says about these two sites. • 4. Each of the 4 sites that we visited at St. Edward St. Park had soils that may or may not have matched what was mapped for that area. Briefly summarize your conclusions as to what was found in the field relative to the soil map and comment on the value of the soils map to management activities.

2. Field Trip Sites: Monday: Upland = Site C Lowland = Site D Wednesday: Upland = Site A Lowland = Site B For Soils: think about productivity, appropriate uses, inappropriate uses, sensitive areas, soils map information Microclimate: any effects with land use changes

3. C D A B

4. Site A – approximately1/3 down hill toward the lake, on a slope

5. Site B Site A =

6. Site B: Approximately 2/3 down hill toward lake, in a side draw

7. Site B

8. Site C: upland area

9. Site C 30 mm

10. Site D: Lowland area downslope from Area C

15. Bulk Density Calculations: Bulk Density = dry soil mass/volume Mineral Soil: core volume of 2 rings = 137.4 cm3 (π r2 h=vol) Organic horizons: average depth of 4 measurements x 18 cm x 11.5 cm (area of book) = volume bulk density = dry weight / volume

16. Soil Horizons, depths and bulk densities

17. Chemical analysis: Total N using a CHN analyzer and dissolved ammonium and nitrate in solution using an Autoanalyzer
