Farming techniques to help reduce soil erosionSoil Conservation Farming techniques to help reduce soil erosion
What is soil conservation?Includes techniques adopted by farmers Assists in management of soil Helps prevent soil erosion Minimizes soil loss
Farming Techniques Conservation Plowing Contour Farming TerracingWindbreaks Strip Cropping Gully Reclamation
Conservation Plowing Disturbs soil and plant cover as little as possible Dead weeds and stalks left in ground Helps retain moisture Returns nutrients
Contour Farming Plant crops along curves of slopeFor gently sloping land Helps slow runoff and soil erosion
Terracing Build up land into stair steps Plant crops on stepsFor steep hills Allows water to soak in rather than run off
Windbreaks Plant trees along edges of fieldBlocks wind from eroding soil
Strip Cropping Alternate different types of crop in same fieldReduces water erosion Returns nutrients to the soil.
Gully Reclamation Gullies occur when water takes same path over and over Fill with hay Slows down speed of water
The Dust Bowl Massive dust storm affecting the Great PlainsOccurred in the 1930’s Caused by: Overfarming Overgrazing Severe Drought Wind
Soil Loss in the Great PlainsDust blew as far as Chicago and New York City Eventually reached Atlantic Ocean Many abandoned depleted farms Soil Conservation Service established in 1935
