Chapter 9 Section 4 Soil Conservation Flashcards
What do we call a method to maintain the fertility of soil by protecting the soil from erosion and nutrient loss?
Soil conservation
What is soil conservation?
A method to maintain the fertility of soil by protecting the soil from erosion and nutrient loss
What does soil provide?
Soil provides minerals and nutrients for plants, housing and habitat for animals, and water storage
How is soil damaged?
Poor farming techniques and over grazing
What is erosion?
The process by which wind, water, ice, or gravity transports soil and sediment from one location to another.
Name four soil conservation methods
Contour plowing, terracing, no-till farming, cover crops
How does contour plowing reduce erosion?
It reduces erosion by slowing the downward flow of water.
How does terracing work?
Terracing creates a series of flat fields that prevent the rapid runoff of water
How does no-till farming work?
No-till farming reduces erosion by providing cover that reduces water runoff.
How do cover crops help?
Cover crops such as soy beans, restore nutrients to soil and reduce soil exposure to wind
