station one south ga
Station One – South GA
  • Rotation – Corn
  • Original Topsoil – 12 inches
  • No Gullies Present
  • pH – 5.5
  • Manure – Available
  • Phosphorus – Medium
  • Potassium – Low
  • Magnesium – Low
  • Check 10 Items
station one south ga3
Station One – South GA
  • Notice the topsoil texture. What does it look like? Remember this is a South Georgia Pit.
  • Where is the point of change?
  • Where does the subsoil end?
  • What is the soil’s permeability? What mostly composes the soil?
  • What is the slope of the land?
  • After finding the topsoil thickness, calculate the erosion.
  • Are gray mottles present? If so, how deep are they?
  • What Land Capability Class is it?

From the photo on the left, you can see the slope of the land. Below, is the actual informational poster from the contest.
station one answers
Station One Answers
  • Topsoil Texture: coarse
  • Topsoil Thickness: thick (11 inches)

Station One Profile

The black arrow in the photograph shows the point of change. The original topsoil thickness was 12 inches. Now, there are only 11 inches remaining. That means that about 8% of the topsoil has been lost due to erosion.
