UNIT GOAL:  Students will demonstrate basic knowledge of common management
            practices used in irrigation and drainage.

____________________________________________________________________________

UNIT OBJECTIVES:  Upon completion of this unit, the students will be able 
                  to:

1.  Define the terms irrigation and drainage.

2.  List sources of irrigation water.

3.  Compare differences in water holding capacities and water infiltration 
    rates of fine and coarse soils.

4.  Name and describe two common drainage systems.

5.  Describe factors that determine water penetration.

6.  Design and demonstrate the set up of two types of irrigation systems. 

7.  Identify three ways of determining when to irrigate. 

8.  Describe how sprinkler irrigation can work as a frost protection method.

9.  Given the appropriate information, calculate the appropriate amount of 
    water needed and the cost for that water for a complete production cycle 
    of a major local crop.

10. Determine the acre feet of water needed to irrigate a local crop.

11. Describe how and why salts (e.g. selenium and nitrate ions) can become a 
    problem in agricultural waste water run-off.

12. Discuss how water in soil can move upward against gravitational pull.

13. Demonstrate how to test for soil moisture content by touch.

14. Calculate soil moisture content.
