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 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• Topsoil Texture: coarse• Topsoil Thickness: thick (11 inches)• Effective Depth: deep• Permeability: moderate• Slope: nearly level• Erosion: none to slight (originally

topsoil 12 inches)• Drainage: well• Land Capability: Class 1 Land

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.

Station One Answers Continued10 Items Checked –

• 1 – because it was Class 1 Crop Land• 5 – because its use was Crop Land• 6 – because its use was Crop Land• 9 – because its use was Crop Land• 21 – because pH was below 6 • 22 – because manure was available• 23 – because Phosphorus was medium• 24 – because Potassium was low• 25 – because non-legume crops were planted• 26 – because Magnesium was low

Station Two – South GA• New Forest Area• Original Topsoil –

24 inches• No Gullies Present• pH – 6.0• Manure – Not

Available• Phosphorus – High• Potassium – High• Magnesium – Low• Check 1 Item

If so, how deep are they?• What Land Capability Class is it?• Remember, since this is FOREST land, there are only 2 options when checking recommended practices. You are instructed to check 1 item.

Station Two Answers• Topsoil Texture: coarse• Topsoil Thickness: very thick (22 inches)• Effective Depth: deep• Permeability: moderate• Slope: very gently sloping (4%)• Erosion: none to slight (original topsoil 24

inches)• Drainage: moderately well drained • Land Capability: Class 2 Land• Practices Checked: 11 – because it was

NEWLY ESTABLISHED FOREST. Only 1 tree was present within the station boundaries.

Station Two Profile

The black arrow in the photograph shows the point

of change. The original topsoil thickness was 24

inches. Now, there are only 22 inches remaining. That

means that about 8% of the topsoil has been lost due to

erosion.

Station Three – North GA• Rotation – Cotton • Original Topsoil – 8 inches• No Gullies Present• pH – 6.1• Manure – Available• Phosphorus – High• Potassium – High• Magnesium – Adequate• Check 10 Items

Station Three Answers

• Topsoil Texture: medium• Topsoil Thickness: moderately thick (7

inches)• Effective Depth: deep• Permeability: moderate• Slope: very gently sloping (4%) • Erosion: none to slight (originally topsoil 8

inches)• Drainage: well drained• Land Capability: Class 2 Land

Station Three Profile

The black arrow in the photograph shows the point of change. The

original topsoil thickness was 8 inches. Now,

there are only 7 inches remaining. That means that about 12.5% of the topsoil has been lost due

to erosion.

Station Four

ProfileThe black arrow in the photograph shows the point of change. The

original topsoil thickness was 7 inches. Now,

there are only 3 inches remaining. That means that about 57% of the

topsoil has been lost due to erosion.
