  1. 2006 Land Judging Contest Tifton, Georgia August 26, 2006 Photos Taken By Jeri Bozeman Slideshow Assembled By Kasey Bozeman

  2. 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

  3. 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?

  4. From the photo on the left, you can see the slope of the land. Below, is the actual informational poster from the contest.

  5. 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

  6. 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.

  7. Station One Answers Continued 10 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

  8. 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

  9. Station Two – 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? • Remember, since this is FOREST land, there are only 2 options when checking recommended practices. You are instructed to check 1 item.

  10. 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.

  11. 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. 

  12. 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

  13. Station Three – North GA • Notice the topsoil texture. What does it look like? Remember this is a North 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? (use poster at contest) • After finding the topsoil thickness, calculate the erosion. • Are gray mottles present? If so, how deep are they? • What Land Capability Class is it?

  14. 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

  15. 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.

  16. Station Three Answers Continued 10 Items Checked - • 2 – because it was Class 2 Crop Land • 5 – because its use was Crop Land • 6 – because it use was Crop Land • 9 – because its use was Crop Land • 14 – because it was Class 2 Crop Land with a slope greater than 2% • 15 – because it was Class 2 Crop Land with a slope greater than 2% • 16 – because it was Class 2 Crop Land with a slope greater than 2% • 17 – because it was Class 2 Crop Land with a slope greater than 2% • 22 – because manure is available • 25 – because non-legume crops were planted

  17. Station Four – North GA • Established Grass Pasture • Original Topsoil – 7 inches • No Gullies Present • pH – 5.7 • Manure – Available • Phosphorus – High • Potassium – Medium • Magnesium – Low • Check 8 Items

  18. Notice the topsoil texture. What does it look like? Remember this is a North 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? (use poster at contest) • After finding the topsoil thickness, calculate the erosion. • Are gray mottles present? If so, how deep are they? • What Land Capability Class is it?

  19. Station Four Answers • Topsoil Texture: medium • Topsoil Thickness: thin (3 inches) • Effective Depth: deep • Permeability: moderate • Slope: gently sloping (8.5%) • Erosion: moderate (originally topsoil 6 inches) • Drainage: well drained • Land Capability: Class 3 Land - due to the slope

  20. Station Four Profile  The 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.

  21. Station Four Answers Continued 8 Items Checked – • 7 – because its use was pasture • 9 – because its use was pasture • 10 – because its use was pasture • 21 – because pH was 5.7 • 22 – because manure was available • 24 – because Potassium was medium • 25 – because its use was pasture • 26 – because Magnesium was low
