VIRTUAL LAND JUDGING - Intermediate Level


   VIRTUAL LAND JUDGING - Intermediate Level
   
      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?
   Medium
   Good
   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?
   Good
   Moderate
   Poor
   
      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?
   Good
   Poor
   Moderate
   
   
      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
   
      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
      
   
   
   
   Score = 
   Correct answers:
   


   Congratulations! You have finished an Intermediate level land
judging example. As you develop confidence in these basic soil
concepts, challenge yourself by judging an Advanced level site.
