Soil Conservation:Ways to preserve (or save) the soil

1. Crop RotationPlanting different crops on the same
field in different years

2. Conservation TillageReducing the number of times fields are tilled, or plowed, in a year

3. TerracesFlat, step-like areas built on a hillside to prevent rainwater from running downhill

4. Contour PlowingPlowing along curves or contours of a slope to prevent water from running straight downhill

5. Wind BreaksRows of trees between fields to “break” or reduce the force of winds.

Soil Conservation ExamplesFind a partner. Read the scenario of erosion. With your partner, decide on a solution to the problem.
Write your solution next to the scenario and then draw a picture of your solution.
