A site in western Kentucky has been selected for you
   to judge. Using the information provided, respond to the
   following questions.   
   

1. The elevation of this site changes 10 feet in a distance
   of 100 feet. What is the percent slope of this site?
   7 %
   10 %
   14%
   
   
      2. Seven inches of topsoil are present at this site. What
   degree of erosion has taken place at this site?
   None to Slight
   Moderate
   Severe
   
   
      3. The soil at this site has a silt loam texture. How would
   the workability of this soil be rated?
   Good
   Medium
   Poor
      
   
      4. The depth of soil above a root zone limiting layer
   "fragipan" is 30 inches at this site. What is the "depth of
   root zone" rating for this site?
   Deep
   Medium
   Shallow
   
      5. Erosion hazard refers to the potiental risk of damage to
   the production capacity of the soil "if" soil erosion should
   occur. Erosion hazard is influenced by steepness of slope
   and depth of root zone. Using your ratings for slope and
   rooting depth, what is the erosion hazard rating for this site?
   None to Slight
   Moderate
   Severe
   Very
   
   

 

6. Subsoil shows gray drainage mottling starting 25 inches from the surface. 
What is the aeration and drainage rating for this site?
Good
Moderate
Poor
Very Poor

7. The combination of soil texture, root zone depth, percentage slope and amount
 of erosion influence the ability of soil to supply moisture to plants. Using the 
ratings you've already assigned to these 4 factors, how would you rate the ability
 to this soil to supply moisture to plants? 
Poor
Moderate
Good 

8. Soils are grouped in capability classes to indicate limitations in use and risk 
of damage by farming practices. Determine the overall capability class 
for this site? 
Class I 
Class II 
Class III
