Agricultural Techniques AKA Types of Farming

Sustainability of Agriculture Sustainability is how the processes used today impact the ability to use the land in the future. Non-sustainable agriculture Large amounts of soil erodes Use chemicals to grow & protect plants (fertilizer, insecticides, fungicides, etc.)

Non-Sustainable Agriculture Techniques Traditional Farming Plow (turn over) soil after each season Removes plant stalks, roots, and loosens soil Causes the most erosion Graze large numbers of livestock (animals) together Called overgrazing Kills plants (eaten faster than they can regrow)

Sustainability of Agriculture Sustainability is how the processes used today impact the ability to use the land in the future. Sustainable agriculture Minimizes erosion (but it still happens!) Minimizes the addition of chemicals

Sustainable Agriculture Techniques No-till Farming Leave plant stalks rooted in fields (do not plow) Terracing Make hills into steps and farm on the flat areas Contour Farming Plant along the shape of the land
