Soil 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 Terracing Windbreaks 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 slope For gently sloping land Helps slow runoff and soil erosion
Terracing Build up land into stair steps Plant crops on steps For steep hills Allows water to soak in rather than run off
Windbreaks Plant trees along edges of field Blocks wind from eroding soil
Strip Cropping Alternate different types of crop in same field Reduces 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 Plains Occurred in the 1930’s Caused by: Overfarming Overgrazing Severe Drought Wind
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

Soil Erosion. Soil – An Important Resource Soil Erosion Soil Erosion Occurs when soil is moved from the place where it formed. Occurs when soil is moved.
Changing Earth’s Surface. Erosion is the process by which natural forces move weathered rock and soil from one place to another. Gravity, running water,
Soil. Soil Formation Over many years, weathering and erosion will cause the formation of soil. Soil is the loose, weathered material on the Earth’s surface.
6.E.2.4 Conclude that the good health of humans requires: monitoring the lithosphere, maintaining soil quality and stewardship.
Soil Conservation. Soil conservation means protecting soils from erosion and nutrient loss. Soil conservation can help to keep soils fertile and healthy.
Soil Conservation Chapter 2 Section 3 Geology. Introduction Prairie soil = very fertile –Rich in humus because of the tall grass Sod=thick mass of tough.
EQ - What are the effects of human activity on erosion and natural resources? Do Now: A forest can be considered a natural resource. Why do you think this.
Human Activities affect Soil Soil is a resource that you can’t live without. Whether its supplying you with food, oxygen, or clean water. It sustains life!
