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
