1.  PowerPoint begins with teacher-led discussion (on next slide)  Necessary materials:  PowerPoint Guide Teacher Information!

2.  What is runoff?  Why is runoff a problem?  What tactics are used to lessen the impacts or runoff? Teacher-Led Discussion

3. Controlling Erosion on the Farm Soil and Water Resources Pgs 67-77 in Ch.6 of Managing Our Natural Resources

4. Students will be able to…  Discuss the different methods that farmers can use to control erosion.  Identify the most important factor of erosion control

5.  Cover crops Close-growing crops protect soil Common in vineyards and orchards Used when erosion danger is severe Improve organic matter content Green manure crop  Cover crop is plowed under Erosion Control Methods (1)

6.  Crop rotation Decreases erosion danger Improves water absorption Increases soil organic matter content  Examples: 3-year rotation  corn, soybeans**, wheat 4-year rotation  corn, cotton, oats, hay **Benefits of legumes? Erosion Control Methods (2)

7.  Strip cropping Alternating bands of different crops  Corn-hay-corn-hay Used in conjunction with crop rotations Provides strip of heavier vegetation  Advantages? Erosion Control Methods (3)

8.  Grassed waterways Drainage ditch covered with dense vegetation Widely used throughout world NOT cultivated Grass may be used for hay Erosion Control Methods (4)

9.  Conservation tillage To till… Economical Conserves soil and water All rely on crop residue to protect soil  Examples? Disadvantages v. advantages? Erosion Control Methods (5)

10.  Contour farming Don’t go up the hill…go around!  Why? Exactly perpendicular?  No… Disadvantage ? Erosion Control Methods (6)

11.  Terracing Large surface channels Controlled rate of fall Conduct water to a protected area Use when slopes are greater than 2% Erosion Control Methods (7)

12.  Windbreaks Often for sheltering buildings Reduce cost of heating/cooling Slows moisture evaporation  Shelterbelts Provide shelter for crops and livestock  Conservation tillage  Contour farming Controlling Wind-Caused Erosion

13.  What is the most important thing that can be done? Use the land according to its CAPABILITY!  Then make use of appropriate erosion control methods. EROSION!

14. Can you…  Identify the different methods that farmers can use to control erosion in the following slides?
