Soil Erosion. What is soil erosion? A natural process of soil moving from one place to another.

Supports the growth of plants, which in turn supply us with many things, such as food, clothing, medicines, lumber, and even oxygen. Supports the growth.

What makes good soil? Air Water Organic Material (Nutrients) Rock particles.

EQ: Why is soil a valuable resource? The Value of Soil Everything that lives on land depends on soil either directly or indirectly Fertile soil is valuable because it is limited in supply Less than 1/8 of the Earth’s soil is suitable for farming EQ: Why is soil a valuable resource? G2-3

EQ: Why is soil a valuable resource? Soil Damage and Loss Soil Loss Over farmed by the same crops Erosion by wind and water Loss of plant cover EQ: Why is soil a valuable resource? G2-3

George Washington Carver Scientist from the early 1900’s, Alabama Developed new crops and farming methods that helped restore farming fertility to the South Planted peanuts in cotton fields to replace soil nutrients EQ: Why is soil a valuable resource? G2-3

EQ: Why is soil a valuable resource? Dust Bowl 1930 - 1938 Cause- plowing removed prairie grass from the Great Plains and exposed the soil - drought occurred turning the topsoil to dust -Wind started blowing soil across the country G2-3

EQ: Why is soil a valuable resource? Soil Conservation Soil Conservation – management of soil to prevent its destruction Ways to conserve soil Contour plowing – plowing land along curves of a slope; slows runoff and prevents soil from washing away Conservation Plowing – disturbs the soil and plant cover as little as possible; leave dead weeds and stalks in ground to help return nutrients to the soil Planting wind screens EQ: Why is soil a valuable resource?
