1 Soil Conservation Farming techniques to help reduce soil erosion

2 What is soil conservation? Includes techniques adopted by farmers Assists in management of soil Helps prevent soil erosion Minimizes soil loss

3 Farming Techniques Conservation Plowing Contour Farming Terracing Windbreaks Strip Cropping Gully Reclamation

4 Conservation Plowing Disturbs soil and plant cover as little as possible Dead weeds and stalks left in ground Helps retain moisture Returns nutrients

5 Contour Farming Plant crops along curves of slope For gently sloping land Helps slow runoff and soil erosion

6 Terracing Build up land into stair steps Plant crops on steps For steep hills Allows water to soak in rather than run off

7 Windbreaks Plant trees along edges of field Blocks wind from eroding soil

8 Strip Cropping Alternate different types of crop in same field Reduces water erosion Returns nutrients to the soil.

9 Gully Reclamation Gullies occur when water takes same path over and over Fill with hay Slows down speed of water

10 The Dust Bowl Massive dust storm affecting the Great Plains Occurred in the 1930’s Caused by: Overfarming Overgrazing Severe Drought Wind

11 Soil Loss in the Great Plains Dust blew as far as Chicago and New York City Eventually reached Atlantic Ocean Many abandoned depleted farms Soil Conservation Service established in 1935
