Field Trip Sites: (Field Report due next Wednesday?)
Tuesday: Upland = Site A
Lowland = Site B
Report: Introduction (briefly summarize methods used), Results(include N data in kg/ha, soil series and map accuracy, productivity, land use)
Soils: think about productivity, appropriate uses, inappropriate uses, sensitive areas, water quality….
Microclimate: any effects with land use changes?

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 measurments x 18 cm x 11.5 cm(area of book)
= volume
bulk density = dry weight / volume
