A moldboard plow tills a paddock on a farm near Arrino, Western Australia. This type of plow turns the soil upside down, bringing the red-yellow subsoil to the surface while burying the grey topsoil below. This process helps to bury resilient weeds and expose fertile soil, allowing a wheat crop to be planted behind the plow.29°21'21.4"S, 115°31'01.6"E
