Ways to Manage Topography
{"Image DocumentName": "Ways to Manage Topography", "Image ImageDescription": "Contour - Plowing and planting across (with the contour) slope to slow flow of water (left). Strip-farming - Planting different crops in alternating strips along land contours (left). Terracing - Shaping land to create level shelves of earth again with the slope to hold water and soil (see next slide). Planting perennial (plants that live >2 years) species. After the dustbowls of the 1930 s and the activities of the Soil Conservation Service (SCS), methods of managing topography and preventing and slowing soil erosion were developed. Particularly, contour plowing and strip farming (where vegetative areas are interspersed with crop areas) were introduced by the SCS and practiced extensively by farmers. These contour plowing and interspersing species were most effective when used in conjunction with terracing. A lot of these types of farming have been undone in the last decades because of the substitution of chemicals and herbicides, and because larger and larger equipment isnecessary for these practices to take place.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
