A sample of soil has a wet weight of 100g, a dry weight of 84g, a bulk volume of
60cm^3, and a particle density of 2.6g/cm^3. Calculate the total porosity of the soil.

, TP = 1-((dry weight/volume)/particle density)
TP = 1-((84/60)/2.6)
TP = 1-(1.4/2.6)
TP = 1-0.54
TP = 0.46
Three days after a 2 inch rain, the movement of water through the soil occurs due to
differences in:

After a growing season of heavy tillage traffic across a soil, a soil property that is least
affected is:

The weathered subsoil horizon, recognized for its accumulation of aluminum and iron
hydrous oxides and organic matter is a horizon called:
