  1. Bell Ringer: Wednesday, October 15th • Explain how the cereal related to three soil horizons? (you can choose the 3) • Update the ToC! (on level) • AC:

  2. Control of Soil ErosionorSoil Conservation A method to maintain the fertility of the soil by protecting the soil from erosion and nutrient loss S6E5 I: Explain the effects of human activity of erosion on the Earth’s surface Standard: S6E5 J: Describe the methods for conserving natural resources such as water, soil, and air

  3. Importance of Soil *On the back of the flip book* • Provides minerals & nutrients for plants • Provides energy and habitats for animals • Water storage & prevention of runoff & flooding • Prevents soil loss & erosion • Overuse causes desertification (aka: land degradation)

  4. No Till Farming • Farmers leave all the old crop in the soil while planting the new crop. A road sign promotes no-till farming. Agriculture and the Environment, 1991 Yearbook: 38 Soybeans growing in corn residue with no-till farming. Agriculture and the Environment, 1991 Yearbook: 17

  5. Windbreaks • Trees planted creating a border on one side of a field. • Cuts down on erosion • Useful in hilly regions

  6. Cover Crops • Plants that grow in winter & spring act as ground cover • Protect from soil erosion • Low to the ground

  7. Contour Plowing/Cultivation • Cultivation - process of loosening up soil between rows of growing crops. • Prevents erosion from heavy rain • Great for sloped lands

  8. Terracing • On extremely steep slopes • Creates a series of steps/terraces • Prevents erosion from heavy rains (washing away the crops)
