8. Ways to Conserve Ways that soil can be conserved include contour plowing, conservation plowing, fallow soil, crop rotation, and terracing. Ways that soil can be conserved include contour plowing, conservation plowing, fallow soil, crop rotation, and terracing.

9. Soil Conservation TYPESEXPLANATION Contour Plowing Conservation Plowing FALLOW Soil Crop Rotation Terracing Crops planted in curving rows. Prevents soil loss as much as 50%. Farmers rotate which plants they use every other season. Crops are NOT planted to keep the soil fertile. A method famers use when plowing, which leaves old crops on top to prevent the topsoil from blowing away. Farmers cut level areas into the side of hills/mountains to slow down water from washing away the soil.
